Students investigate robotics that don’t use a computer to process logic. In this project, simple analog components to create a motor driver circuit that responds to light.
Electronics tools
Simple car with 2 gear motors
6V battery pack
Solderless breadboard
2 power transistors: TIP 120
2 potentiometers: 10k
2 photoresistors
Students use a robot car kit or build their own with hobby motors and wheels. Adjust the potentiometers to match the light levels in the space and balance the performance of the motors.
