Robots you can build with AI

Talk to it: AI voice desk robots

Cheap ESP32 boards plus a local or cloud LLM give you a desk robot you talk to. JARVIS Desk Bot speaks progress updates while your agent works. XiaoZhi and Stack-chan are the most popular firmware bases. Reachy Mini is the polished option.

• JARVIS Desk Bot: a talking ESP32 desk robot for your AI agent
• Build an ESP32 AI voice robot with XiaoZhi and MCP
• Make Stack-chan, the cute M5Stack desk robot
• Give Reachy Mini a real-time voice and personality
• Set up Reachy Mini as a talking desk companion

Give your Hermes Agent a body

Hermes Gadget turns an ESP32-S3 board or a Raspberry Pi into a hold-to-talk voice terminal for your own Hermes Agent, and you can try it in a desktop simulator before you buy a board. Caduceus goes further: a foam-board ESP32 robot with four servos that Hermes moves through MCP tools. JARVIS Desk Bot, above, is the third option.

• Hermes Gadget: an ESP32 or Raspberry Pi voice body for your Hermes Agent
• Caduceus: a voice robot body for Hermes Agent, wired up over MCP

Let an agent drive a robot arm

Give a coding agent a tiny Python API for an SO-101 and it can draw, paint and check its own work on camera. Or train a vision-language-action model so the arm follows plain-English tasks. AIfred adds a projector so ChatGPT's help lands right on your desk.

• Let a coding agent drive an SO-101 to paint or draw
• Run SmolVLA on an SO-101 so it follows plain-English tasks
• AIfred: a robot arm + projector that puts ChatGPT on your desk

Connect any ROS robot to an LLM

ROS MCP Server and NASA JPL's ROSA let Claude, ChatGPT or Gemini inspect topics and send commands to existing ROS robots, with no changes to robot code.

• Control any ROS robot from Claude or ChatGPT with ROS MCP Server
• Ask your robot questions in plain English with NASA JPL's ROSA

Agents with hands: phones and homes

A $7 ESP32 lets a vision model tap and type on a real iPhone. Stretch AI and OK-Robot let you ask a mobile manipulator to fetch things around the house.

• Let an AI agent use a real iPhone with a $7 ESP32
• Tell Stretch 3 to pick up objects around your home
• Pick and place in a real home with zero training (OK-Robot)
