25 May 2026 » Tearing down a Coder Dojo Kingston University robotOur 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... -
07 Jun 2025 » Preparing for the coder dojoLast night, I got some preparation for today’s Coder Dojo KU Python Robotics activity. These are MicroPython robots based on an RP2040 (the Raspberry Pi Pico chip). The activity is aimed at kids learning to code. I have a fleet of 10 robots, plus 1 more as a demo/test model. It uses some of the principles from my books. These autonomous car type robots are built around the Cytron MakerPi RP2040 control board, with a dual RCWL-1601 sensor for obstacle avoidance, a Maker Line 5-sensor array, and a mini-3 round chassis. The code is written in MicroPython, and the kids write their own code to control them, with us providing activity sheets, reference cards, and helping out if they run into problems.more... -
14 Oct 2023 » Choosing parts for the coder dojo robotsI am a regular mentor at a Coder Dojo Kingston University, a place where we mentor children on their journey to learn about programming and technology. I’ve mostly been mentoring in Python there, but they have also had robot tracks, on and off.more... -
I’ve recently been specifying changes to a fleet of robots used in my local Coder Dojo. The modified robots would be based on a Raspberry Pi Pico W, and a bunch of sensors.more... -
