The 3D model so101-81bf5a6d35e1.glb and the measurement data that come with it are derived from "SO101 Assembly.step" (SO-101 arm by TheRobotStudio), https://github.com/TheRobotStudio/SO-ARM100: the file STEP/SO101/SO101 Assembly.step at commit 5f6d2b876a53a4872e405b991dd925556c9e38a4, 20496014 bytes, sha256 f754be35708382b05ce65768ae33c612f91dca11ad19d14807dc637eb944ba3d. It is licensed under the Apache License, Version 2.0, which is in LICENSE.txt. Changes: stepstr converted the STEP file's exact geometry into triangle meshes with OpenCascade, simplified them, and added edge lines and the B-rep face id of every vertex. The vertices were then reordered, quantized to 16-bit positions and 10-bit normals, and compressed with meshoptimizer, and the measurement data was cut down to the parts the page measures. The names, colours and assembly structure are the STEP file's. These changes are stepstr's, not the model's authors'.
