Pinchy the bestest boi
summary
Pinchy is a Raspberry Pi–powered six‑legged scorpion robot that claims autonomous mapping and navigation using SLAM and computer vision; the build uses Raspberry Pi with ROS2, a rotating LIDAR and driver boards to run 25 servos, three‑segment 3D‑printed body, claws and a tail. The live demo dies gloriously but recorded demos show it walking; SLAM integration currently fails to compute odometry so maps collapse, and power distribution and joint strength are practical limits after ~700 hours of work.
