The robots on this site are drawn from the manufacturers' own open-source descriptions, and the site is built on open-source software and typefaces. Thank you to the people who make and share them.

Robot models

The point clouds of the factory floor are sampled from the meshes and kinematic descriptions below. We changed the material: meshes were converted to point samples, posed, placed on a sample floor, given motion paths and recoloured. The original files are not served by this site.
