Summary
This chapter was about interfacing I/O boards to ROS and adding sensors on it. We have discussed the interfacing of the popular I/O board called Arduino to ROS, and interface's basic components, such as LEDs, buttons, accelerometers, ultrasonic sound sensors, and so on. After looking at the interfacing of Arduino, we discussed how to set up ROS on Raspberry Pi 2 and Odroid-XU4. We also presented a few basic examples in Odroid and Raspberry Pi based on ROS and Wiring Pi. Finally, we looked at the interfacing of smart actuators called DYNAMIXEL in ROS.
