In the last chapter, we worked with Kai to reinforce the concepts covered in the previous chapters and to introduce new ideas and information to fill in the knowledge gaps. In addition, Kai worked really hard and practiced extensively through various solved examples, clever exercises, and projects that simulated real-world problems. This practice helped him to better explore and discover new programming topics. As a result, this practice will improve his communication with the robot and his ability to control the robot to do what Kai needs it to do.
