An embedded application for toy-car controlling based on Raspberry Pi 3 Model B and AlphaBot2-Pi.

This is the source codes of my programming assignment of the course Embedded Applications on Intelligent Systems (2020 Fall) at NJU.

• Motor
  • Going foreward or backward
  • Turning left or right
• Infrared remote control
• Obstacle avoidance
• Self tracing
• Real-time camera
• Monitor and control by web
  • Interactive
  • Programmable

python -m picar

There is a demo which uses a fake car implement. It is fully Python codes, so it doesn't need any embedded devices. Use the following commands to run it.

python -m picar --demo
