Range sensing is a crucial element of any environment and obstacle mapping system for mobile robotics applications. Sensors that are suitable for the environment and obstacle mapping include 2D Ladar and 3D Ladar. However, a cost-effective approach for the environment and obstacle mapping is to mount a 2D laser scanner that is aimed forward and downward on the front end of a mobile robot.
Using a Laser Rangefinder – Hokuyo
Getting ready
In this section, we will learn how to use a low-cost model of Lidar which is widely used in robotics applications, such as Hokuyo URG-04LX. The Hokuyo Laser Range Finder is similar in function to the Sick Laser Range Finder, which has been the de-facto standard range sensor for mobile...
