Summary

In this chapter, we discussed creating plugins for the ROS visualization tool (RViz) and writing basic ROS controllers. We have already worked with default controllers in ROS, and in this chapter, we developed a custom controller for moving joints. After building and testing the controller, we looked at RViz plugins. We created a new RViz panel for teleoperation. We can manually enter the topic name; we need the twist messages and to enter the linear and angular velocity in the panel. This panel is useful for controlling robots without starting another teleoperation node. In the next chapter, we will discuss interfacing of I/O boards and running ROS in embedded systems.
