This is the actual collider

Not a stand-in. Every triangle below ships inside the .usdz — it is the geometry PhysX collides against. Drag to orbit. Push it and see whether it slides or goes over.

Why colliders and not a pretty render. A render tells you nothing about whether the physics is any good. Most marketplace assets hide a bounding box behind a nice texture, and your robot then collides with a shape the object does not have. Every hull you can see here was produced by convex decomposition of the real mesh — — of them on this asset — and they are what ships.
Honest labelling. The drop animation is a visual replay for scale and proportion. The numbers in the drop-test panel come from harness/03_droptest.py running pybullet at 240 Hz, included in every download so you can re-run them. The slide-and-tip figures are statics you can check by hand: F_slide = µ·m·g and F_tip = m·g·(b/2)/h, with the centre of mass assumed at the geometric centre.
