Summary

Thanks for reaching the end! I hope you enjoyed reading this chapter as much as I enjoyed writing it. This field is very interesting; we have just touched on it a little, but I hope that this chapter will show you a direction for your own experiments and projects. The goal of the chapter wasn't building a robot that will stand, as this could be done in a much easier and more efficient way; the true goal was to show how the RL way of thinking can be applied to robotics problems, and how you can do your own experiments with real hardware without having access to expensive robotic arms, complex robots, and so on.

At the same time, I see some potential for the RL approach to be applied to complex robots, and who knows, maybe you will build the next version of iRobot Corporation to bring more robots into our lives. If you are interested in buying the kits for the robot platform described in this chapter, it would be really helpful if you could fill out this form: https:...
