Remote-control Car

Demo Slides

Software

• React - can add a video component later on if I want to stream an RPi camera
• FastAPI - no need to write custom C++ firmware code using pyfirmata
• Ubuntu Core 22
• Docker Buildx - can add a container app sending autonomous movement commands to FastAPI later on

Hardware

• Arduino
• RPi4
• L298N motor driver - can be replaced by L293D to make compatible for stronger motors for bigger cars (like a delivery robot)
• Robot body - wiring diagram from OpenBot, modified smartphone brain with RPi
