Rotational Joint Motor control

Hi,

I’m trying to set up a simulation with a rotational joint. I control the joint using the component “PhysicsJointControl.”

Moving the joint in one direction works properly, but I would like to rotate it both clockwise and counterclockwise. This doesn’t seem to work. If I add a second “PhysicsJointControl” with a different value, the joint only moves in the direction defined by the latest component.

For example:
First component “PhysicsJointControl” → clockwise value -110 deg/s
Second component “PhysicsJointControl” → counterclockwise value +50 deg/s

Is it possible to control the joint in both directions?

Why have you made it with a component instead of making a mechanism for the joint?

I created a physical rotational joint that has several configurable properties, such as a motor, a spring, or an angle. Since the axis in this mechanism cannot rotate indefinitely, I thought this approach would be better. However, I cannot control the motor in both directions.

In this mechanism, I would have to set a very large rotation angle if I want to perform, for example, 10 full rotations.

Does this not work?

I.e. that you write the value for the desired speed, negative and positive, via another component.

Unfortunately not.

Now i created a mechanism with a rotatable joint and 7200 deg to get 20 full rotations.

maybe this will work for me.
