Hi Fin,

We have done a similar project of light painting with our KR10-R1100-2.
As pointed out by Johannes you can use the built in I/O from the wrist after you have mapped them in workvisual.

We use simple 24v relays to link the robot 24v outputs to the arduino 5v Inputs and this works fine. Like this you can define in grasshopper/kuka PRC when to turn the LED on and use the arduino to control more advanced settings of your LED (like special blinking pattern or color change for example).

Hello Johannes,

Thank you for the custom file, it does work great !

Hello Johannes,

Thank you for your reply.
Yes I have tried the AA's setup and it is a horizontal turntable, which works fine in the example as long as I keep the robot looking to the side.

When I compensate in the base to bring it back to behing vertically aligned with axis Z, the simulation starts giving me troubles.
I have attached the files using the turn table example with the AA's table after base compensation (B 90).
As you can see I have the robot turning around the workpiece and I cannot seem to find a way to fix that.

Thanks again for your help.

Hello everyone,

I have been trying to simulate a horizontal turn table (or rotating mandrel) from the turn table example in kuka|prc.
I can easily change the C component of the turn table block to 90 which rotates the robot model 90° to simulate a horizontal turn table configuration, but then in the viewport I have a horizontal robot which makes it hard to navigate around. At that point the simulation works fine with the turntable rotating the work piece (Z is still the turntable rotating axis).

I tried to compensate by adding a -90 to the base C component which effectively brought back the robot to be vertical and the turntable horizontal (Y axis rotating axis).
However I have issues with the turntable simulation with the robot turning around the piece and not the turntable rotating (I did rotate the work piece mesh and the cylinder surface to be horizontal and aligned to the turntable).

I have played quite a lot with orientations to try to solve the issue but I cannot seem to make it work for a horizontal turntable.

Has anyone tried to set up a similar turntable simulation ?

Thanks in advance !
