Chapter 11. building with gears
You can use gears to transfer motion from one rotating axle to the next. For example, you can transfer the motion of a rotating motor to the wheels of a robot to make it drive. Gears can also be used to change the output speed and torque of a rotating axle.
A series of gears used to transfer motion is called a gear train. In this chapter, you’ll begin learning how gears work as you experiment with a basic gear train. You’ll then see how the gear ratio controls the performance of the gear train. Finally, you’ll explore each of the gears in the EV3 set and discover how you can use them effectively in your own robots.
