co-arm is a 3D-printed four-joint camera arm built from ST3215 serial-bus servos, an ESP32 servo HAT and a Raspberry Pi 4. Codex previews each move before running it, then reads the joints and camera to check the result. The author says Codex has moved the physical arm; demo media is not published yet. The software is source-available for noncommercial use.

Edison Science Corner built a Wi-Fi camera rover on a Seeed XIAO ESP32S3 Sense with an L293D motor driver without writing code. Seeed's CodeCraft assistant generated the firmware and wiring instructions and flashed the board from the browser. The 5-minute video shows assembly, the 3D-printed chassis, live streaming and joystick control. Its description carries Seeed affiliate links.

Tal Raviv connected Claude to a SunFounder PiCar-X through a terminal on its Raspberry Pi, with camera photos as feedback. The robot saved notes, learned gentler turns and a three-point turn, and spent about 15 minutes parking at a filing cabinet instead of 20 cm from the door. The post embeds an edited demo video.

Ori Grossman built a tilt maze game on a PIC24FJ256GA705 Curiosity board with Claude Code agents, an ADXL345 accelerometer and a 96x96 OLED. One agent drove the board's debugger through MPLAB's mdb command line and traced an I2C driver bug that dropped queued bytes. The README has a photo of the game running.

Sigurd Enghoff replaced the WLKATA MT4 desktop arm's stock firmware and built a vision and MCP control stack on top. His ATmega2560 firmware runs Cartesian moves on the arm, ArUco markers calibrate a fixed camera, and an MCP server takes requests from Claude Code or Cursor. Linked videos show the arm stacking cubes and following typed instructions.

Tech With Anant rebuilt the Saras rover around Claude Code running on a Raspberry Pi 4. A small MCP server exposes the motors, encoders and camera as tools, and a CLAUDE.md file sets the robot's identity. An LD06 lidar handles obstacle detection. The 24-minute video shows the rover in a live test, driving toward a named object around obstacles.

Amer El-Saad built a 3-DOF tower crane for his master's thesis that Claude plans and drives through 4 MCP tools. One overhead camera, YOLOv8 and ArUco markers locate parts and stations in centimeters. An Arduino Uno drives the DC motors, and code rejects any route that crosses a worker. README photos show the crane and live detections.

Claude Code wrote serial scripts for the STS3215 servos of a self-assembled SO-101 arm and fixed GR00T N1.6-3B fine-tuning errors for a Japanese maker. It set motor IDs, showed live gripper values and ran training over SSH on a DGX Spark. After 97 recorded episodes, the post's GIF shows the arm placing a block in a cup on its own.

Wired's Will Knight connected OpenClaw and Codex to a LeRobot SO-101 arm with a camera. Codex configured the connections, helped calibrate the joints and wrote a script that grips a red ball the camera sees. OpenClaw then guided training of a control model, checking its error rate after each run. The article's clips show the arm at work.

Norihide Mikami used Claude Code with Opus 4.7 to write a Flask control system for a DENSO six-axis arm in one 4.5-hour hackathon session. It drives the arm over b-CAP, an IAI electric gripper over Modbus RTU, a 4K Basler GigE camera, a webcam and a PS5 gamepad. The three-minute video shows the system running.

lego-robot-mcp has Claude Code drive a LEGO robot with two wheels, a gripper and an arm on a Raspberry Pi 4 with a Build HAT. Claude sees through a Pi Camera on the robot and an overhead iPhone, and a Gemini Robotics-ER model checks frames after each move. The README has no photos or video of the robot.
