Yes, it's yet another hobby robot, like many of those based on Arduino. So, to make it more fun, it features:

• Raspberry Pi Pico instead of an Arduino board
• My own tiny asynchronous event loop (since CircuitPython doesn't have one)
• Custom «asynchronous» BNO055 driver
• Multiple asynchronous tasks running «at the same time»
• Simple REPL over Bluetooth
• Schematics & PCB design included
