How to Build a Shitty Robot (mariozechner.at) AI

A maker describes turning a €10 low-cost toy robot into an LLM-powered, phone-controlled STEM project by disassembling it, hijacking its single-motor PCB via an Adafruit FT232H, and rebuilding the body from cardboard. The build uses a TypeScript client-server setup where the phone streams audio and renders tool actions while a laptop server handles speech-to-text, an LLM/agent, text-to-speech, and simple memory, with a voice pipeline designed for interactive “barge in” responses.
