Yesterday the Raspberry Pi Foundation launched a new device called the Raspberry Pi TV HAT. It is a small board, TV antenna that lets you decode and stream live TV. The TV HAT is roughly the size of a Raspberry Pi Zero board. It connects to the Raspberry Pi via a GPIO connector and has a port for a TV antenna connector. The new Raspberry Pi addon is designed after a new form factor of HAT (Hardware Attached on Top). The addon itself is a half-sized HAT matching the outline of Raspberry Pi Zero boards. Source: Raspberry Pi website TV HAT specifications and requirement The board addon has a Sony CXD2880 TV tuner. It supports TV standards like DVB-T2 (1.7MHz, 5MHz, 6MHz, 7MHz, 8MHz channel bandwidth), and DVB-T (5MHz, 6MHz, 7MHz, 8MHz channel bandwidth). The frequencies it can recieve are VHF III, UHF IV, and UHF V. Raspbian Stretch (or later) is required for using the Raspberry Pi TV HAT. TVHeadend is the recommended software to start with TV streams. There is a ‘Getting Started’ guide on the Raspberry Pi website. Watch on the Raspberry Pi With the TV HAT can receive and you can view television on a Raspberry Pi board. The Pi can also be used as a server to stream television over a network to other devices. When running as a server the TV HAT works with all 40-pin GPIO Raspberry Pi boards. Watching on TV on the Pi itself needs more processing, so the use of a Pi 2, 3, or 3B+ is recommended. The TV HAT connected to a Raspberry Pi board: Source: Raspberry Pi website Streaming over a network Connecting a TV HAT to your network allows viewing streams on any device connected to the network. This includes computers, smartphones, and tablets. Initially, it will be available only in Europe. The Raspberry Pi TV HAT is now on sale for $21.50, visit the Raspberry Pi website for more details.

Yesterday, Facebook launched two brand new video communication devices. Named Portal and Portal+, these devices let you video call anyone, with more richer, hands-free experiences. The Portal features a 10-inch 1280 x 800 display, while Portal+ features 15-inch 1920 x 1080.  Both devices are powered by Artificial Intelligence. This includes a Smart Camera and a Smart Sound technology. Smart Camera stays with the action and automatically pans and zooms to keep everyone in view. Smart Sound minimizes background noise and enhances the voice of whoever is talking, no matter where they move. Source: Facebook Portal can also be used to call Facebook friends and connections on Messenger even if they don’t have Portal. It also supports group calls of up to seven people at the same time. Portal also offers hands-free voice control with Amazon Alexa built-in which can be used to track sports scores, check the weather, control smart home devices, order groceries, and more.  Facebook has also enabled shared activities in its Portal devices by partnering with Spotify Premium, Pandora, iHeartRadio, Facebook Watch, Food Network, and Newsy. Keeping in mind, it’s security breach that affected 50 million users two weeks ago, Facebook says it has paid a lot of attention to privacy and security features. Per their website, “We designed Portal with tools that give you control: You can completely disable the camera and microphone with a single tap. Portal and Portal+ also come with a camera cover, so you can easily block your camera’s lens at any time and still receive incoming calls and notifications, plus use voice commands. To manage Portal access within your home, you can set a four- to 12-digit passcode to keep the screen locked. Changing the passcode requires your Facebook password. We also want to be upfront about what information Portal collects, help people understand how Facebook will use that information and explain the steps we take to keep it private and secure: Facebook doesn’t listen to, view, or keep the contents of your Portal video calls. In addition, video calls on Portal are encrypted. For added security, Smart Camera and Smart Sound use AI technology that runs locally on Portal, not on Facebook servers. Portal’s camera doesn’t use facial recognition and doesn’t identify who you are. Like other voice-enabled devices, Portal only sends voice commands to Facebook servers after you say, “Hey Portal.” You can delete your Portal’s voice history in your Facebook Activity Log at any time.” In all the above, Facebook seems quite cryptic about audio data. It also doesn’t really explain how it will use the information it collects from users. The voice data is stored on the Facebook server by default, probably to improve the Portal’s understanding on the user’s language quirks and to understand the user’s needs from the data. But it does make one wonder, should this be an opt-in and not an opt-out by default? Another jarring aspect is the need for one’s Facebook password to change the device’s passcode. This just feels like the new devices are yet another way for Facebook to add users to Facebook, not to mention the fact that Facebook just had a data breach on its site, the repercussions of which they are still investigating. In an interesting poll conducted by Dr. Jen Golbeck, Professor at UMD, on Twitter, over 63% of respondents said that they will not trust Facebook to responsibly operate a surveillance device in their home. https://twitter.com/jengolbeck/status/1049343277110054912 Read more about the devices on Facebook’s announcement.

At the Xilinx Developer Forum in San Jose, Arm announced its collaboration with Xilinx, the market leader in FPGAs. The collaboration plans to bring the benefits of Arm Cortex-M processors to FPGA through the Arm DesignStart program, thus providing scalability and a standardized processor architecture across the Xilinx portfolio. Users can expect a fast, completely no-cost access to soft processor IP, while taking advantage of the easy design integration with Xilinx tools and comprehensive software development solutions to accelerate success on FPGA. These processors will enable embedded developers to design and innovate confidently, while benefiting from simplified software development and superior code density. In addition, products can be easily scaled on these processors, thanks to the support of the broadest technology ecosystem of software, tools, and services provided by the team. Arm for FPGA comes with the following benefits: #1 Maximum choice and flexibility Users can obtain an easy and instant access to Cortex-M1 and Cortex-M3 soft processor IP for FPGA integration with Xilinx products. They will not be charged any license fee or royalties for this access. #2 Reduced software costs The processor focuses on reducing software costs while obtaining maximum reuse of software across an entire OEM’s product portfolio on a standardized CPU architecture, scaling from single board computers through to FPGAs. #3 Ease of design The team has ensured an easy integration with Xilinx system and peripheral IP through Vivado Design Suite. They use a drag-and-drop design approach to create FPGA systems with Cortex-M processors. The extensive software ecosystem and knowledge base of others designing on Arm, will ultimately result in reducing the time to market for these processors #4 Measures to Combat FOSSi (free and open source silicon) threat Arm Cortex-M1 includes a mandatory license agreement, which contains clauses against reverse-engineering. The clause also prevents the use of these cores for comparative benchmarking. These clauses will assist Arm to enable IP holds up against the latest and greatest FOSSi equivalents (like RISC-V) when running on the same FPGAs. This is not the first time that Arm has raised its voice against FOSSi threats. Earlier this year, they had also launched an aggressive marketing campaign specifically targeting RISC-V. The Arm and Xilinx collaboration will enable developers to take advantage of the benefits of heterogeneous computing on a single processor architecture.

An open-source libre GPU project is under the works by Luke Kenneth Casson Leighton. He is the hardware engineer who developed the EOMA68, an earth-friendly computer. The project already has access to $250k USD in funding. The basic idea for this "libre GPU" is to use a RISC-V processor. The GPU will be mostly software-based. It will leverage the LLVM compiler infrastructure and utilize a software-based Vulkan renderer to emit code and run on the RISC-V processor. The Vulkan implementation will be used for writing in the Rust programming language. The project's current road-map has details only on the software side of figuring out the RISC-V LLVM back-end state. Work is being done on writing a user-space graphics driver, implementing the necessary bits for the proposed RISC-V extensions like "Simple-V". While doing this, they will start figuring out the hardware design and the rest of the project. The road-map is quite simplified for the arduous task at hand. The website notes: “Once you've been through the "Extension Proposal Process" with Simple-V, it need never be done again, not for one single parallel / vector / SIMD instruction, ever again.” This process will include creating a fixed-function 3D "FP to ARGB" custom instruction, a custom extension with special 3D pipelines. With Simple-V, there is no need to worry about about how those operations would be parallelised. This is not a new concept, it's borrowed directly from videocore-iv. videocore-iv calls it "virtual parallelism". It's an enormous effort on both the software and hardware ends to come up with a RISC-V, Rust, LLVM, and Vulkan open-source combined project. It is difficult even with the funding considering it is a software based GPU. It is worth noting that the EOMA68 project was started by Luke in 2016 and raised over $227k USD from crowdfunding participants and hasn't shipped yet.

California likes to be leading the way when it comes to digital regulation. Just a few weeks ago it passed legislation that looks like it could restore net neutrality. Now, a bill designed to tighten IoT security, is with the governor awaiting signature for it to be carried into California state law. The bill, SB-327 Information privacy: connected devices, was initially introduced in February 2017 by Senator Jackson. It was the first legislation of its kind in the US. Approved at the end of August, it will come into effect at the start of 2020 once signed by Governor Jerry Brown. Read next: IoT Forensics: Security in an always connected world where things talk What California’s IoT bill states The new IoT security bill covers another of important areas. For example, for manufacturers, IoT devices will need to contain certain safety and security features: Security should be appropriate to the nature and function of the device. The feature should be appropriate to the information an IoT may collect, contain, or transmit. It should be designed to protect the device and information within it from unauthorized access, destruction, use, modification, or disclosure. If an IoT device is requires authentication over the internet, further conditions need to be met, such as: The preset password must be unique to each device that is manufactured. The device must ask the user to generate a new authentication method before being able to use it for the first time. It’s worth noting that the points mentioned above for IoT security are not applicable to IoT devices that are subject to security requirements under federal law. Also a covered entity like a health care provider, business associate, contractor, or employer subject to the Health Insurance Portability and Accountability Act of 1996 (HIPAA) or the Confidentiality of Medical Information Act is exempt from the title points mentioned. The IoT is a network of several of devices that connect to the internet via Wi-Fi. They are not openly visible as most of them are used in a local network but often do not have many security measures. The bill doesn't have any exact definitions for a ‘reasonable security feature’ but provides a few guiding points in interest a user’s security. The legislation states: “This bill, beginning on January 1, 2020, would require a manufacturer of a connected device, as those terms are defined, to equip the device with a reasonable security feature or features that are appropriate to the nature and function of the device, appropriate to the information it may collect, contain, or transmit, and designed to protect the device and any information contained therein from unauthorized access, destruction, use, modification, or disclosure, as specified.” Criticisms of the IoT bill Some cybersecurity experts have criticised the legislation. For example, Robert Graham writes on his Security Errarta blog that the bill is “based on a superficial understanding of cybersecurity/hacking that will do little improve security, while doing a lot to impose costs and harm innovation.” He explains that “the point [of good cybersecurity practice] is not to add ‘security features’ but to remove ‘insecure features’.” Graham’s criticisms underline that while the legislation might be well-intentioned, whether it will be impactful remains another matter. This is, at the very least, a step in the right direction by a state that is keen to take digital security and freedom into its own hands.

Earlier last week, a team of US scientists, from Florida Atlantic University (FAU) and the US Office of Naval Research published a paper on five jellyfish robots that they have manufactured. The paper is titled Thrust force characterization of free-swimming soft robotic jellyfish. The prime motive of the scientists to build such robotic jellyfish is to track and monitor fragile marine ecosystems without causing unintentional damage to them. These soft robots can swim through openings narrower than their bodies and are powered by hydraulic silicon tentacles. These so-called ‘jelly-bots’ have the ability to squeeze through narrow openings using circular holes cut in a plexiglass plate. The design structure of ‘Jelly-bots’ Jelly-bots have a similar design to that of a moon jellyfish (Aurelia aurita) during the ephyra stage of its life cycle before they becoming a fully grown medusa. To avoid the damage to fragile biological systems by the robots, soft hydraulic network actuators are chosen. To allow the jellyfish to steer, the team uses two impeller pumps to inflate the eight tentacles. The mold models for the jellyfish robot were designed in SolidWorks and subsequently, 3D printed with an Ultimaker 2 out of PLA (polylactic acid). Each jellyfish has varying rubber hardness to test the effect it has on the propulsion efficiency. Source: IOPScience What this study was about? These jelly robots will help the scientists in determining the impact of the following factors on the measured thrust force: Actuator material Shore hardness Actuation frequency Tentacle stroke actuation amplitude The scientists found that all three of these factors significantly impact mean thrust force generation, which peaks with a half-stroke actuation amplitude at a frequency of 0.8 Hz. Results The material composition of the actuators significantly impacted the measured force produced by the jellyfish, as did the actuation frequency and stroke amplitude. The greatest forces were measured with a half-stroke amplitude at 0.8 Hz and a tentacle actuator-flap material Shore hardness composition of 30–30. In the test, the jellyfish was able to swim through the narrow openings than the nominal diameter of the robot and demonstrated the ability to swim directionally. The jellyfish robots were tested in the ocean and have the potential to monitor and explore delicate ecosystems without inadvertently damaging them. One of the scientists, Dr. Engeberg said to Tech Xplore: "In the future, we plan to incorporate environmental sensors like sonar into the robot's control algorithm, along with a navigational algorithm. This will enable it to find gaps and determine if it can swim through them." To know more in detail about the jellybots, read the research paper published by these scientists.

A team of researchers from Ulsan National Institute of Science and Technology (UNIST) in South Korea has developed an ultrathin, and transparent wearable device that is capable of turning your skin into a loudspeaker. The device has been created to help the hearing and speech impaired people. However, it has potential applications in other domains such as wearable IoT sensors, and healthcare devices.                                                Skin-attachable NM  loudspeaker This new device is created with conductive hybrid nanomembranes (NMs) with nanoscale thickness, comprising an orthogonal silver nanowire array embedded in a polymer matrix. This helps substantially enhance the electrical as well as mechanical properties of ultrathin polymer NMs. There is no loss in the optical transparency because of the orthogonal array structure. “Here, we introduce ultrathin, conductive, and transparent hybrid NMs that can be applied to the fabrication of skin-attachable NM loudspeakers and microphones, which would be unobtrusive in appearance because of their excellent transparency and conformal contact capability” as mentioned in the research paper. Hybrid NMs help significantly enhance the electrical and mechanical properties of ultrathin polymer NMs, which can then be intimately attached to the human skin. After this, the nanomembrane is used as a loudspeaker which can be attached to almost anything to produce sounds. The researchers also introduced a similar device, which acts as a microphone that can be connected to smartphones and computers for unlocking voice-activated security systems. Skin-attachable and transparent NM loudspeaker The researchers fabricated a skin-attachable loudspeaker using hybrid NMs. This speaker is capable of emitting thermoacoustic sound with the help of temperature-induced oscillation of the surrounding air. This temperature oscillation is caused by Joule heating of the orthogonal AgNW array upon the application of an AC voltage. The sound emitted from the NM loudspeaker is then analyzed with the help of an acoustic measurement system. “We used a commercial microphone to collect and record the sound produced by the loudspeaker. To characterize the sound generation of the loudspeaker, we confirmed that the sound pressure level (SPL) of the output sound increases linearly as the distance between the microphone and the loudspeaker decreases” reads the research paper. Wearable and transparent NM microphone The researchers also designed a wearable and transparent microphone using hybrid NMs combined with micropatterned PDMS (NM microphone). This microphone is capable of detecting sound and recognizing a human voice. These wearable microphones are sensors, which are attached to a speaker's neck for sensing the vibration of the vocal folds.                                        Skin-attachable NM Microphone The skin-attachable NM microphone comprises a hybrid NM mounted to a micro pyramid-patterned polydimethylsiloxane (PDMS) film. This sandwich-like structure helps precisely detect the sound and vibration of the vocal cords by the generation of a triboelectric voltage. The triboelectric voltage results from the coupling effect of the contact electrification as well as electrostatic induction. This sensor works by converting the frictional force that is generated by the oscillation of the transparent conductive nanofiber into electric energy. The sensitivity of the NM microphone in response to sound emissions is evaluated by fabricating two device structures, such as a freestanding hybrid NM, integrated with a holey PDMS film (NM microphone), and another fully adhered to a planar PDMS film without a hole. “As a proof-of-concept demonstration, our NM microphone was applied to a personal voice security system requiring voice-based identification applications. The NM microphone was able to accurately recognize a user’s voice and authorize access to the system by the registrant only” reads the research paper.   For more details, check out the official research paper.

Image source mysmartprice Google has been pretty successful with its smart home devices like Google Home series but after Amazon teased its smart home device with screen called 'Amazon Echo Show' Tech giant was keen to work on a product to compete with its rival. If the leaked news from "MySmartPrice" is to be believed, with Google Home Hub powered by Google assistant we can watch YouTube, HBO, and videos from other content providers. Additionally, the device will also display time, weather, daily commute information and other regular Google assistant features.  However, it will not have full-fledged Android OS. While the device comes power packed with the Google software but based on leaks, what seems to be missing from the device is the camera. It would have been perfect if the device sported a camera as well which could have been used for video calling as Google is aggressively marketing its video calling app Google Duo. The device will, however, feature  WiFi and Bluetooth. Image source: mysmartprice With the new device, Google might also introduce new features for the Google assistant. Though there is no confirmation from Google regarding the product yet but the timing makes perfect sense as Google's upcoming event on October 9th would be the perfect place to announce a Google Home Hub along with its much awaited Pixel smartphone series.

Sphero, a robotic toy building company announced their latest Bolt robotic ball aimed at teaching kids basic programming. It has advanced sensors, an LED matrix, and infrared sensors to communicate with other Bolt robots. The robot itself is 73mm in diameter. There’s an 8x8 LED matrix inside a transparent casing shell. This matrix displays helpful prompts like a lightning bolt when Bolt is charging. Users can fully program the LED matrix to display a wide variety of icons connected to certain actions. This can be a smiley face when a program is completed, sad face on failure or arrow marks for direction changes. The new Bolt has a longer battery life of around two hours, charges back up in six hours. It connects to the Sphero Edu app to use community created activities, or even to build your own analyze sensor data etc. The casing is now transparent instead of the opaque colored ones from previous Sphero balls. The sphere weighs 200g in all and houses infrared sensors that allow the Bolt to detect other nearby Bolts to interact with. Users can program specific interactions between multiple Bolts. The Edu app supports coding through drawing on the screen or via Scratch blocks. You can also use JavaScript to program the robot to create custom games and drawing. There are sensors to track speed, acceleration, and direction, or to drive BOLT. This can be done without having to aim since the Bolt has a compass. There is also an ambient light sensor that allows programming the Bolt based on the room’s brightness. Other than education, you can also simply drive BOLT and play games with the Sphero Play app. Source: Sphero website It sounds like a useful little robot and is available now to consumers for $149.99. Educators can also buy BOLT in 15-packs for classroom learning. For more details, visit the Sphero website. Is ROS 2.0 good enough to build real-time robotic applications? Spanish researchers find out. How to assemble a DIY selfie drone with Arduino and ESP8266 ROS Melodic Morenia released

Last Friday, a group of Spanish researchers have published a research paper titled ‘Towards a distributed and real-time framework for robots: evaluation of ROS 2.0 communications for real-time robotic applications’. This paper talks about an experimental setup exploring the suitability of ROS 2.0 for real-time robotic applications. In this paper, ROS 2.0 communications is evaluated in a robotic inter-component communication hardware case running on top of Linux. The researchers have benchmarked and studied the worst case latencies and characterized ROS 2.0 communications for real-time applications. The results indicate that a proper real-time configuration of the ROS 2.0 framework reduces jitter making soft real-time communications possible but there were also some limitations that prevented hard real-time communications. What is ROS? ROS is a popular framework that provides services for the development of robotic applications. It has utilities like a communication infrastructure, drivers for a variety of software and hardware components, libraries for diagnostics, navigation, manipulation, and other things. ROS simplifies the process of creating complex and robust robot behavior across many robotic platforms. ROS 2.0 is the new version which extends the concepts of the first version. Data Distribution Service (DDS) middleware is used in ROS 2.0 due to its characteristics and benefits as compared to other solutions. Need for real-time applications in robotic systems In all robotic systems, tasks need to be time responsive. While moving at a certain speed, robots must be able to detect an obstacle and stop to avoid collision. These robot systems often have timing requirements to execute tasks or exchange data. By not meeting the timing requirements, the system behavior will degrade or the system will fail. With ROS being the standard software infrastructure for robotic applications development, demands rose in the ROS community to include real-time capabilities. Hence, ROS 2.0 was created for delivering real-time performance. But to deliver a complete, distributed and real-time solution for robots, ROS 2.0 needs to be surrounded with appropriate elements. These elements are described in the papers Time-sensitive networking for robotics and Real-time Linux communications: an evaluation of the Linux communication stack for real-time robotic applications. ROS 2 uses DDS as its communication middleware. DDS contains Quality of Service (QoS) parameters which can be configured and tuned for real-time applications. The results of the experiment In the research paper, a setup was made to measure the real-time performance of ROS 2.0 communications over Ethernet in a PREEMPT-RT patched kernel. The end-to-end latencies between two ROS 2.0 nodes in different machines was measured. A Linux PC and an embedded device which could represent a robot controller (RC) and a robot component (C) were used for the setup. An overview of the setup can be seen as follows: Source: LinkedIn Some of the results are as follows: Source: LinkedIn The image describes the Impact of RT settings under different system load. They are a) System without additional load without RT settings. b) is system under load without RT settings. c) is system without additional load and RT settings. d) is system under load and RT settings. The results from the experiment showed that a proper real-time configuration of the ROS 2.0 framework and DDS threads greatly reduces the jitter andworst-casee latencies. This mean a smooth and fast communication. However, there were also some limitations when there is noncritical traffic in the Linux Network Stack is in picture. By configuring the network interrupt threads and using Linux traffic control QoS methods, some of the problems could be avoided. The researchers conclude that it is possible to achieve soft real-time communications with mixed-critical traffic using the Linux Network stack. However hard real-time is not possible due to the aforementioned limitations. For a more detailed understanding of the experiments and results, you can read the research paper. Shadow Robot joins Avatar X program to bring real-world avatars into space 6 powerful microbots developed by researchers around the world Boston Dynamics’ ‘Android of robots’ vision starts with launching 1000 robot dogs in 2019

Shadow Robots Company, experts at grasping and manipulation for robotic hands announced that they are joining a new space avatar program named AVATAR X. This program is led by ANA HOLDINGS INC. (ANA HD) and Japan Aerospace Exploration Agency (JAXA). AVATAR X aims to accelerate the integration of technologies such as robotics, haptics and Artificial Intelligence (AI), to enable humans to remotely build camps on the Moon, support long-term space missions, and further explore space from Earth. In order to make this possible, Shadow will work closely with the programme’s partners, leveraging its unique teleoperation system that it has already developed and that is also available to purchase. AVATAR X is all set to be launched as a multi-phase programme. It aims to revolutionize space development and make living on the Moon, Mars and beyond, a reality. What will AVATAR X program include? AVATAR X program will comprise of clever elements including Shadow’s Dexterous Hand, which can be controlled by a CyberGlove worn by the operator. This hand will be attached to a UR10 robot arm controllable by a PhaseSpace motion capture tool worn on the operator’s wrist. Both the CyberGlove and Motion Capture wrist tool have mapping capability so that the Dexterous Hand and the robot arm can mimic an operator’s movements. The new system allows remote control of robotic technologies while providing distance and safety. Furthermore, Shadow uses an open source platform providing full access to the code to help users develop the software for their own specific needs. Shadow’s Managing Director, Rich Walker says “We’re really excited to be working with ANA HD and JAXA on the AVATAR X programme and it gives us the perfect opportunity to demonstrate how our robotics technology can be leveraged for avatar or teleoperation scenarios away from UK soil, deep into space. We want everyone to feel involved at such a transformative time in teleoperation capabilities and encourage all those interested to enter the AVATAR XPRIZE competition.” To know more about AVATAR X in detail, visit ANA Group’s press release.

iRobot, the intelligent robot making company revealed its latest robot vacuum, the Roomba i7+ yesterday. It is a successor to the Roomba 980 which was launched in 2015. The i7+ has two key changes - it stores a map of your house and empties the trash itself. https://www.youtube.com/watch?v=HPgxcETuqzI Weighing about 7.4lbs, the Roomba i7+ is designed to be easier to manage than the previous models. The new charging base houses a larger trash bin for automatic emptying. The stationary base automatically sucks the debris out of the Roomba into the bag. The base has the capacity to hold dirt of 30 cleanings. This would mean you’ll have to empty the bigger trash bag only once a month, depending on your cleaning needs. The i7+ works with two rubber brushes, one to loosen up the dirt and another to lift and collect it. The large bag in the base traps dust so that it can’t escape. It works on iAdapt® 3.0 Navigation with vSLAM® technology both of which are patented. They allow the robot to map its surroundings and clean sections of your home systematically. It creates visual landmarks to keep track of areas it has cleaned and areas pending to clean. Source: iRobot The i7+ too like the older models connect to the iRobot Home app and can sync with virtual assistants like Alexa to schedule cleanings. Like the previous 900 series, the i7+ too maps your house, the difference being that the newer model stores the map for automatic navigation later. You can use the app to differentiate and name different rooms and control the cleaning frequency. With an assistant, you can use voice commands to clean specific rooms. The i7+ will be available in stores from October. The price tag of $949 may not appeal to everyone, but if you want your house to be cleaned automatically, this is something to consider. There is also a lower- priced model, the i7 with a price tag of $699. This version does not have a self-cleaning base or mapping features, but it can be controlled by Wifi or an assistant. You can pre-order the latest Roomba i7+ from the iRobot website.
