CCC: the compact chimney climber
Many NXT robots move on wheels, some move on legs, and still others do something while remaining in place. But the Compact Chimney Climber (CCC) that you’ll build in this chapter is different: It moves vertically. This robot climbs between two walls, as if up a chimney, as shown in Figure 15-1. When it reaches the top of the “chimney,” it safely returns to the ground.
