ORCA hand Combined extended ORCA hand

Orcahand Description

This repository contains the description files for the Orcahand model (Both URDF and MJCF). The 'extended' version contains additional bodies (incl. inertial properties) such as the camera mount, the U2D2 board and fans.

Example Usage

  1. Clone the repository: 
    git clone git@github.com:orcahand/orcahand_description.git
cd orcahand_description
  2. Install the required dependencies: 
    pip install mujoco
  3. Simulate the orcahand in mujoco: 
    python3 -m mujoco.viewer --mjcf=scene_combined.xml

Note on Meshes

Visual meshes contain the following amount of faces:

  • Main tower, camera & fans: 15'000
  • Rest of base: 2'000
  • Skin: 5'000
  • Rest: 500

Collision meshes contain the following amount of faces:

  • Main tower, camera & fans: 7500
  • Rest of base: 1000
  • Skin: 500
  • Rest: 250

You can further reduce or mirror meshes using the utils/mesh_utils.py script. With the same script, you can also print their number of faces. Some extra dependencies are required:

cd utils
pip install -r utils_requirements.txt

We can also recommend the VSCode extension mtsmfm.vscode-stl-viewer for quickly visualizing STL meshes.
