UC Berkeley has released Berkeley Humanoid Lite, an open-source humanoid robot costing under $5,000. All components are either 3D-printable or available on Amazon, eliminating the need for specialized manufacturing and breaking the high-cost barrier.
The design uses cycloidal gears optimal for 3D-printed actuators, with durability tests validating the plastic parts. The robot demonstrates capabilities like playing with Rubik's cubes, writing, and bipedal walking, utilizing zero-shot sim-to-real transfer via reinforcement learning. Hardware designs and code are fully open-sourced.
