In this chapter, you learned how to use wheels and axles. You applied these to your robot and built your own rover with wheels using the BOOST kit. You also learned about new programming blocks such as set motor direction, repeat loop, and forever loop. We also looked at two different types of turns that are commonly used when coding robots to make them turn; that is, point and swing turns.
In the next chapter, you will be introduced to the fascinating world of gears and how to apply them to build a geared robot. You will perform a few activities to understand concepts such as gear up and gear down. This is going to be a lot of fun!
