Enter the DC gear motor, available in literally thousands of sizes, styles, and other permutations. With the right gear ratio, DC gear motors can zip your robot across the floor; with the right electronics, DC gear motors provide a high level of control of that speed.
The Teachbot DC, described in this chapter, demonstrates the fundamentals of using DC gear motors to drive a robot. It’s designed around the same base as the Teachbot Servo described in Part 1 of this book. But instead of being powered by R/C servo motors, ...
