Python modules to control a robot car that is connected to 2 DC motors and a variety of sensors. The car is controlled by a Raspberry Pi Zero 2w and can operate in two modes:
- Autonomous Mode - Follows a tape on the flor automatically (GIF)
- Manual Mode - Lets you manually control the cars movement
Pi_Car.pysets up a socket server on the local network and listens to inputs from a client. It contains the scripts to follow the tape, avoid obstacles and be controlled manually.remote_control.pyis the second important script, which runs on the laptop. It detects key inputs and sends input commands to the pi-car using a simple python client server connection.
