Hello,

being close to a singularity while using the IK functionality is never a good idea, since this will indeed result in an instable behaviour. You can somehow mitigate this by "pre-tensioning" the incriminated joint in the desired direction. Also adding damping and increasing the maximum number ...

Hello,

do you have any error message?
It seems you are mixing the legacy remote API (in your script attached to UR5) with the ZeroMQ remote API (your Python script). Just remove the script in your scene.

Then it is fine to handle IK on the Python side, but it would be better if you'd handle it on ...

Hello,

you say that nothing is being drawn on the cuboid.

• Can you draw onto e.g. the floor?
• Is the pen tip touching the cuboid?
• Is the cuboid detectable? (remember that the felt pen is using a proximity sensor to detect surfaces to draw onto)

Cheers

In your sysCall_sensing function, your measuredData is a local variable: logically it will be nil in function getMeasuredData.

Cheers

Hello,

you are calling sim.callScriptFunction in an old fashion. Please try following:

In an empty scene add a non-threaded lua script, rename it to scriptAlias , and add following function to it:

function test(a, b, c)
print(a, b, c)
return {1, 2, 3}
end

The from your Python ZeroMQ remote ...

Thank you for the feed-back. Can you tell us how you resolved the issue? What was the problem?

We also encountered several general problems (e.g. sound, visual, app exec.) since the last Windows update, but those resolved gradually by themselve. The last Windows upodate is know to cause severe ...

Hello,

this typically is related with your driver/graphic card. Try to adjust settings in your windows environment. e.g. enable/disable Hardware-accelerated GPU scheduling , Optimizations for windowed games , refresh rate , and all the GeForce-specific settings .
When did the problem start? Do you ...

Hello,

drag and drop the RG2 model into the scene, then run the simulation. Then type:

sim.setIntProperty(sim.handle_scene, 'signal.RG2_open', 1)

Does that open the gripper? Then do:

sim.setIntProperty(sim.handle_scene, 'signal.RG2_open', 0)

Does that close the gripper? This works here ...

The first returned value should be exactly the same as for the C version of the same API function. If your vision sensors do not trigger a detection, then this is normal. By default, a vision sensor does not trigger a detection. To trigger a detection, attach a simulation script to the vision sensor ...

Can you reproduce the problem when using a script instead of a plugin? (i.e. calling sim.handleVisionSensor instead of simHandleVisionSensor)

sim.handleVisionSensor is basically implemented in a same way and should produce the same error. Here the sim.handleVisionSensor implementation:

int ...
