Teleoperated Robot Arm Pair — LeRobot AI Imitation Learning | Robo Kids

Kids Robot Arm is a pair of desktop articulated arms — one leader, one follower — built on the open-source LeRobot platform used by university labs and Hugging Face's robotics research team. Move the black leader arm with your hand, and the white follower arm copies every joint in real time. Record what the follower does, and the RobotiMaker AI agent can learn to repeat the task on its own: pick and place, stack blocks, sort colours, pour water. This is the same imitation-learning setup that professional robotics researchers use, packaged for a young maker's desk.

What's in the box:

• 1× black leader arm — 5 joints + parallel-jaw gripper, back-driveable servos

• 1× white follower arm — matching kinematics, position-controlled servos

• Shared control board with USB-C to host

• All servo cables, power supplies and mounting hardware

• Non-slip base pad + starter block set for grasping practice

• Illustrated quick-start guide and QR code to the online build manual

What Kids Robot Arm can do:

• Teleoperation — grab the leader, the follower mirrors every joint instantly

• Record & replay — teach a task once by demonstration, the arm repeats it forever

• Imitation learning — record 10-20 demonstrations, the AI generalises to new positions

• Vision-guided grasping (with optional camera) — the AI sees the object and plans the grip

• Sort and stack — colour blocks, dice, coins, small toys

• Serve as a research platform — publishes datasets in the LeRobot format

• Fully compatible with Hugging Face's LeRobot library and public datasets

Why this arm matters:

• Open standard — hardware + firmware + training scripts all public and modifiable

• Back-driveable leader — no exoskeleton, no controllers to learn, just move it with your hand

• Research-grade repeatability at a maker price point

• 5 rotational joints + gripper = same DOF as many industrial pick-and-place arms

• All the AI training pipelines used by university robotics labs, running locally on your Pi

What you'll need (not in the kit):

• A Raspberry Pi 5 recommended (Pi 4 works for teleoperation, tight for training) — grab one alongside your arm or reuse an existing one

• A phone, tablet or laptop for the RobotiMaker dashboard (free apps for iOS + Android)

• A USB-C power supply per arm (bundled)

• Optional: USB webcam for vision-based tasks

• A responsible adult supervising first setups

Great for:

• Kids age 12+ curious about robotics and AI

• Home schoolers wanting a real STEM lab on their desk

• University students prototyping imitation-learning research

• Hobbyists who want to train an arm to do a repetitive household task

Includes lifetime firmware updates, free iOS & Android app, browser dashboard, illustrated online build manual, sample recorded-task library, and friendly support if you get stuck.
