  • Tearing down a Coder Dojo Kingston University robot
    Our Coder Dojo at Kingston University runs a fleet of 11 Raspberry Pi RP2040 robots — a design that evolved from my Robotics at Home with Raspberry Pi Pico book. After a recent session, one robot came back needing repair: a sheared standoff and some wiring attention. I figured I’d document the design while I had it apart.more...
  • How to add line following to a robot with Raspberry Pi Pico and Python
    Line following robots are a great example of autonomous robot behaviour. In this article, I will show you step-by-step how to add a line sensor to a Raspberry Pi Pico robot, how to wire it in, and then how to write Python code for responsive line following on the robot. I include CircuitPython and MicroPython examples.more...
  • Idea for an ooPIC based line follower robot
    I had an idea for building an ooPIC based line follower. I’d not had time to build it, but here are the concepts.more...
