Introduction
Sparki has a gripper. It will be useful to learn how to use it before we move to more complex tasks. We will be using the gripper in future lessons.
How it Works
The gripper is a simple mechanism driven by a stepper motor, the same kind of motor used to move Sparki’s wheels. The stepper motor’s shaft has a pinion attached, which drives a rack:
Thus, moving the motor in one direction opens the gripper, while moving the motor in the other direction closes it.
