HANDS-ON STEAM PROJECT
WiFi-Controlled Robot Car
Explore wireless commands and a small wheeled robot.
Instructions and Learning Resources
Learning outcomes
Understand wireless input, motor drivers, power distribution, and safety stop logic.
Parts
WiFi-capable controller, compatible motor driver, two or four wheel chassis and properly rated power supply.
Build outline
- Assemble the chassis and connect the driver to motors.
- Check power rails and common ground.
- Test local direction control before enabling WiFi commands.
- Implement connection-loss timeout and a stop command.
Keep initial tests on a stand so the wheels cannot unexpectedly drive the robot off a surface.
