In a move that will surely delight robotics labs and ambitious garage tinkerers everywhere, Asimov Inc. has open-sourced the complete design for its bipedal robotic system, dubbed Asimov Legs. The company dropped the full mechanical CAD files, a list of actuators, and simulation models onto GitHub, effectively handing the community a starter kit for building a pair of sophisticated robot legs.
The design features a respectable six degrees of freedom (6-DOF) per leg, an RSU ankle architecture, and passive toe joints for more natural movement. Crucially, the entire system is designed to be built with off-the-shelf components and parts made via Multi Jet Fusion (MJF) 3D printing, putting it within reach of well-equipped research institutions and startups. The open-source package includes STEP files for the mechanical components and XML files for simulation in the popular MuJoCo physics engine.
Why is this important?
Building a functional bipedal robot is monstrously expensive and complex, with hardware development being a primary barrier. By releasing a complete, validated leg design under a permissive CERN-OHL-S-2.0 license, Asimov is allowing researchers to bypass a huge chunk of that initial hardware struggle. This lets teams focus their limited time and budgets on the arguably more difficult challenges of software, controls, and AI. While you won’t be building a full-fledged Optimus competitor overnight, Asimov just gave everyone a serious leg up. Your move, rest of the robotics world.
