In addition to deepening my knowledge of Rust Embedded, the challenge was to make the most of standard LEGO parts, the servo, the motor, and especially the power supply (LEGO Power Functions pack of 6 AA batteries).

Non LEGO parts are mostly a Raspberry Pico W (for Wi-Fi control), an arducam (video stream), a Kitronik 5331, a buck converter, and a lot of jumper cables.

What I found most interesting, as a Rust programer, is how similar the backend and embedded code are. Even with the constraints of no_std, the parallel code running on the small Pico looks like your standard rust backend, even while there's no OS and almost no memory on this small chip.
