You Don’t Need to Buy a $16K Optimus to Tear It Down to the Bolts

Movez posted a webpage called RoboLabs in a tweet. Click into it and you land in a 3D hangar holding 10 real robots, including Tesla Optimus and Unitree G1.

Its core function is straightforward: each robot can be broken down into 35 to 45 parts. You can reassemble it in the order of frame, actuators, battery, sensors, and shell, then finally tighten the bolts. Once assembled, you can test movements: walking, running, jumping, backflipping, or stacking boxes with a warehouse robotic arm.

Movez says all the 3D models on the page were generated in code by Fable 5.2, without using ready-made 3D files or photos. This detail matters more than “looking cool.” For developers, geometry, materials, and interaction are all described in code, meaning later changes and extensions cost less; for ordinary users, the code-generated result is already intuitive enough to let them open up a humanoid robot and see its internal hierarchy.

Note the WebGL requirement. When the external link is fetched, the page only shows Hangar doors are shut and Robot Hangar needs WebGL. This message means the browser has not enabled WebGL or hardware acceleration; it does not mean the page has no content. If you see the same message, first try switching to a different browser or enabling hardware acceleration.

In the comments, some people thought this was a robot fighting game, and Movez replied that it is a high-fidelity laboratory. Others went straight for the Optimus teardown and said they would click on it first. That reaction is not surprising: real humanoid robots are expensive, and breaking one is costly, so most people never get a chance to see the internal structure.

RoboLabs works well as an observation entry point. In Ronin’s September article, a six-month robotics engineer roadmap, learning is broken into electronics, microcontrollers, motors and sensors, CAD, ROS 2, control and perception, and LeRobot. The article makes a very practical point: a robotics portfolio is made of things that move; completed courses don’t count. RoboLabs can help you first see the parts hierarchy of a humanoid robot clearly, but it does not replace soldering boards, tuning PID, and getting a robot to actually walk.

A backflip in the browser won’t break motors; a real robot will. The value of this tool is that it lowers the friction of the first step: first look, then take it apart, then decide whether to buy dev boards and servos.
