Not another robot kit. A programmable robotics platform with an onboard GPU.
Lucen is a modular robotics platform designed to be taken apart. Start with a bipedal robot to train locomotion policies. Swap six parts — a matter of minutes with a hex key — and the same actuators, controllers, and firmware become a dexterous arm ready for manipulation research. Every part is reusable. Every file is public.
Two legs, twelve actuators, one hex key away from every joint. Built for researchers, students, and hobbyists training their first RL locomotion policy — or their tenth. Runs standard MuJoCo, Isaac Sim, and real-world sim2real pipelines out of the box.
Single-leg mode also available for students focused on control theory fundamentals before committing to full bipedal balance.
When you're done with locomotion, unscrew six parts, plug in two extra actuators, flash a different firmware branch — and the same kit becomes a 7-DoF manipulator with a compliant gripper. Same servos, same controller, same host software.
For $350 more than the Biped, you get a complete manipulation research platform. Ships with a Jupyter notebook that runs an ACT baseline on a pick-and-place task in under an hour of teleop data.
Firmware, teleop tools, and training notebooks are on GitHub. No account required.
Every commercial robotics kit becomes a paperweight the day a servo dies. Lucen is designed the opposite way — every part swaps in seconds, every line of firmware is on GitHub, and every servo lives a second life in a different configuration.
Six parts is all that separates the Biped from the Arm. Unscrew, replug, reflash. Every joint is symmetric, every connector is keyed, every actuator is field-replaceable without a soldering iron.
Every line of firmware and every SDK primitive is on GitHub under MIT. Fork the controller, remap the actuators, write your own policy interface. You bought a platform, you own the software.
Ships with LeRobot integration, MuJoCo XML, Isaac Sim scenes, and starter notebooks for ACT, SmolVLA, and RL locomotion baselines. Get from unboxing to first trained policy in a weekend.
The same modular parts are heading in three more directions. None of these are for sale yet — announcing soon.
A bimanual configuration built from the same swap parts.
A wheeled platform carrying the same upper body and compute.
Our own actuator, designed and built in house.
