Let's discuss the components of the robot using the labeled picture as an aid (shown in the following figure):
Components of the robot
The following is an explanation for the components of the robot:
- The Raspberry Pi Zero controls the movement of the robot using a motor driver circuit (stacked on top of the Raspberry Pi Zero)
- The motors of the robot are connected to the motor driver circuit
- A USB battery pack is used to power the Raspberry Pi Zero. A separate AA battery pack is used to drive the motors
- The robot is also equipped with a camera module that helps with driving the robot
We have included a suggested list of components where we chose the cheapest source available for the component. You are welcome to substitute with your own components. For example, you can use a webcam instead of using the Raspberry Pi camera module:
