Berkeley Humanoid Lite offers a more accessible humanoid robot design thanks to 3D-printed actuators that make up most of its body. The modular actuators, consisting of a motor, a printed cycloidal gearbox, and a magnetic encoder, can also be used in different projects.
Rather than being a completed product, the robot is an open-source and customizable reference design, with its files available on GitHub; basic demonstrations include VR-controlled teleoperation. The total hardware cost is under $5,000 USD.
Why it matters
This approach transforms humanoid robot development from the process of purchasing a single-piece product into a workspace where the hardware and software can be modified. The open files lower the barrier to entry for researchers, students, and developers who want to examine the project or adapt it to their own requirements. The ability to use the modular actuators in different projects means the work can also be evaluated through its mechanical components, without being limited to the robot as a whole. However, the fact that the reference design is not a completed product shows that details such as assembly, software compatibility, and performance in real-world use cases are left to the user. Therefore, the key open question is how the low hardware cost will be balanced against the additional workload during the implementation and development process.
