[Question] Franka robot asset model gravity and coriolis compensation

[mikelasa]

Hello,

I'm working in a cartesian impedance control using a usd based franka model imported from:

from omni.isaac.orbit_assets import FRANKA_PANDA_HIGH_PD_CFG # isort:skip

This is how I load the robot:

# articulation
    Right_robot = FRANKA_PANDA_HIGH_PD_CFG.replace(prim_path="{ENV_REGEX_NS}/Right_robot")
    Right_robot.init_state = FRANKA_PANDA_HIGH_PD_CFG.init_state.replace(
        joint_pos={
            "panda_joint1": 0.0,
            "panda_joint2": -0.569,
            "panda_joint3": 0.0,
            "panda_joint4": -2.810,
            "panda_joint5": 0.0,
            "panda_joint6": 3.037,
            "panda_joint7": 0.741,
            "panda_finger_joint.*": 0.04,
        },
    )
    Right_robot.init_state.pos = (0.0, 0.0, 0.0)
    Right_robot.init_state.rot = (0.0, 0.0, 0.0, 0.0)
    Right_robot.spawn.rigid_props.disable_gravity = True

I'm able to activate a deactivate the gravity compensation term but I dont see anything related to the coriolis and centripetal term. Is integrated within the robot model or is something that I have to compute by myself?

My final torque equation demands a coriolis term that I need to compute.

Tanks in advance and regards, Mikel

You can get these quantities from the root physx view methods.

Closing this issue since there's no activity and above solution should work.
