Hello, in the very first simulation step, before the physics engine is even called, there is no dynamic state. And in that case, the function will return None . The easiest solution would be to skip the very first simulation step in your sysCall_actuation function. Cheers Edit: actually, we will cha...

For hydraulic cylinders, I'd use prismatic joints in position control mode.

If you need anything more fancy, then use a custom control mode, and write your own controller for that (via a joint callback function).

Can you provide a minimalistic Python client code that would trigger that error? (maybe with a related minimalistic scene)

Hello, best would be to not use any of the simOMPL API functions in an external client: wrap all OMPL functionality inside of child script functions, that you can call from your external client via the ZeroMQ remote API via sim.callScriptFunction. Something like: function findPath(inputArg1, inputAr...

Hello, make sure that sim is accessible from your code location. Making sim global is one possibility. But the error message ...one of the function's argument type is not correct. is directly caused by CoppeliaSim, not MATLAB. That means that your function call to sim.setJointTargetVelocity was succ...

Hello,

see my answer to your other post.

Hello,

please use the ZeroMQ remote API, which is much faster, flexible and easy to use. The legacy remote API is deprecated.

Hello,

simply this:

Code: Select all

    for i = 1:obj.number_of_joints
        %Read from joints
        armJoints(i) = sim.getJointPosition(obj.jointHandle{i})
    end

Cheers

Hello,

I didn't understand what the exact problem was, when you say that it doesn't seem to work, nor does it give any output... does that mean the CoppeliaSim hangs? Or that the script stops running eventually? Until what point is the script executed?

Cheers

coppelia

Please share the scene file.

Cheers
