  • Introduced two collision boxes as pads for each finger.

How it was tested

The changes were verified using the Mink Python library, with results documented in #83.

Thank you @s1lent4gnt! Can you add a little Changelog section in the README (see the unitree_g1 for an example) to describe succinctly the changes you made in this PR?

Hey @kevinzakka, I’ve added references to both the Issue and this PR in the Changelog section. Does this look okay, or would you prefer not to include them?

- Adding two collision box meshes as pads for each finger.
- Setting `armature=0.1` for the joints.

These changes resolve [issue #83](https://github.com/google-deepmind/mujoco_menagerie/issues/83) and are implemented in [PR #131](https://github.com/google-deepmind/mujoco_menagerie/pull/131).

I'd prefer removing this part if possible (the issue/PR part).

BTW, feel free to add your name next to "Improved object grasping" --> (thanks to @s1lent4gnt)
