Electronics

  • This project uses a Raspberry Pi 4, which is powered by the USB powerbank.
  • The motors are connected to the Explorer Hat; the two left motors connect to Motor 1 and the two right motors to Motor 2.
  • The Arducam connects to the CSI camera module connector on the Raspberry Pi.
  • The Lidar connects to the Raspberry Pi via the USB Port. (a later update may change this to connect directly via 2 GPIO pins).

ROS2 Python code

A later update will provide the code.
