Standard Open Arm-100 5DOF - Version 1.3 (MJCF)
Important
Requires MuJoCo 3.1.6 or later.
Overview
This package contains a simplified robot description (MJCF) of the Standard Open Arm-100 developed by The Robot Studio. It is derived from the publicly available URDF description.
URDF → MJCF derivation steps
- Added
<mujoco><compiler discardvisual="false" strippath="false"/></mujoco>
to the URDF’s<robot>
element to preserve visual geometries. - Loaded the URDF into MuJoCo and saved it as a corresponding MJCF.
- Manually edited the MJCF to extract shared properties into the
<default>
section. - Edited original meshes: extracted servos into separate files, manually created convex collision meshes for the gripper jaws.
- Added extra box-shaped collision geoms to the gripper for additional contact points.
- Added an
exclude
clause to prevent collisions betweenBase
andRotation_Pitch
. - Added approximate joint limits.
- Added position-controlled actuators.
- Added
impratio="10"
andcone="elliptic"
attributes for improved no-slip behavior. - Created
scene.xml
to include the robot, along with a textured ground plane, skybox, and haze.
