Our Collection
Select from our diverse lineup of advanced robotic systems, each designed for specific applications and research needs.
A leader-follower dual arm system — both arms are 6-DOF (5 joints + 1 gripper). The operator physically moves the leader arm, and the follower arm mimics it in real time, capturing training data for imitation learning.
The follower arm uses 6× STS3215 servos (all at 1/345 gear ratio). The leader arm uses 3 different gear ratios (1× 1/345, 2× 1/191, 3× 1/147) to make it easy to move by hand. Motors run on 12V (follower) and 7.4V (leader).
Dual camera setup — one mounted on the gripper, one external — for precise manipulation and environmental awareness.
No gear removal needed during assembly, improved wiring to prevent joint disconnection, wires routed externally, easier 3D print for the wrist, base no longer needs a small screwdriver.
The leader arm can now follow the follower arm in real-time, enabling human correction during reinforcement learning training.
~$220–$240 for the motor kit (3D printed parts sold separately or printable from open-source files).
Fully integrated with LeRobot — PyTorch datasets, training, simulation, and deployment. Compatible with NVIDIA Jetson edge devices.
