Upside-down robot uses flipped reference frame

When I place the robot upside down, it's like the robot's frame of reference is flipped. The robot "thinks" that the down is up and is looking for items above itself.

Software Version:

FlexSim 16.1.2

I'm not sure I completely understand what you're describing. I tried to recreate a "flipped robot" but it seemed to be acting as expected after I reset an ran my example. Could you provide an example?

@Sam Stubbs

Maybe post your example to look at?

That's a good idea, sadly I didn't save it. All I really did was make a simple source > queue > processor > exit model. And threw in a robot as the operator, then just rotated it upside down. But it didn't act or move strangely, I think I'll have to see Bartosz model.

Thank you for replys. That's an example of flipped robot which doesn't work. I mean it's picking up a flowitem from the ceiling and there are bugs when using Define Motion Path also.

It looks like the issue was proximity to the queue. I'm not exactly sure why that seems to mess up the coordinates of the robot's pickup/dropoff destination, but if you spread the queues out just a bit further, it seems to allow the robot to move correctly.
