In one week of nights I: Reverse engineered the cloud signing algorithm for a 3i G10+ robot vacuum (matched 18/18 wire captures from mitmproxy) Frida-hooked the patched APK to capture the live SLAM map blob and AES-decrypted Agora WebRTC credentials Built a 5,000-line Python + aiohttp dashboard with cost tracking, behavior rules, MJPEG streaming, an autonomy decision loop Routed Claude vision (Haiku 4.5, $0.003/call) into the live drive loop so the robot stops crashing Handed motor control to Claude with a written autonomy contract + persistent memory across sessions Got a robot vacuum to TTS "Mission control online. Claude has command. Hello, Tesco." through my apartment at 2 AM Total daily AI spend at peak: $0.89. Crashes: 0. Things learned: a lot. The setup The hardware is a 3i G10+ ("Tesco"). Sells for ~€400, runs Aliyun's IoT cloud (Living Link), Flutter mobile app.…
