Trimesh does support loading Collada meshes (.dae), it uses pycollada under the hood. But it requires the installation of trimesh[easy] (instead of trimesh, see https://trimsh.org/install.html). I will update the dependencies accordingly!
I've tried to reproduce your tests but, for some reason, it doesn't work out of the box.
You are mentioning this repo: https://github.com/ankurhanda/robot-assets as robots test input.
The problem is that some of the robots are using ".dae" format for geometry which "trimesh" doesn't accept as input. I guess you didn't change manually the mesh geometry format for those robots, right?
