6. Project: Robot Flower

In this chapter you build another robot. This one is a Robot Flower that opens and closes its petals with the help of a pair of motors (see Figure 6.1). I show you how to build the Flower and then show you two ways to control it. The first method uses the usual EV3 Intelligent Brick, with the program moving the motors incrementally as commanded by the program.
