Watch the robot move, then move each joint yourself within its real limits: the part it moves lights up. MuJoCo runs in your browser: nothing runs on Robotheca's servers, and no code from the repository runs.
Downloads the creator's MuJoCo files from GitHub (at most 83.9 MB; the URDF's are 4.8 MB), once: your browser keeps them for next time.
Files come from GitHub at commit 4a0ef2c: the creator's MuJoCo scene (simulation/scene.xml) when it loads, else the URDF. Walking and balancing need the creators' own controllers and are not simulated here.
