Hands-On ROS for Robotics Programming

Dynamic simulation using Gazebo

In the previous chapter, you performed a very basic version of navigation, where the feedback to the robot about its environment always came from you as a human operator. For example, you saw that GoPiGo3 is advancing to an obstacle, so you made it turn left or right to avoid it.

This section takes you one step forward in remote control by providing feedback not only from your human vision, but also from robotic sensors. More precisely, GoPiGo3 will provide data from the Pi camera and from its distance sensor. The goal is that you can teleoperate it more precisely by getting as high-quality sensor data as possible. You may be able to guess at least two common scenarios in the real world where this kind of manual ...
