I am using Yaskawa robot , i have a real cell and i design it in the Visual Component same as real robot, the distance between devices are same (of course it can have some different).
I will use OLP function and after that load program on the real robot. I do it and the robot can move but there are some deviation between path in Real robot and Visual component robot cell. How can i increase the accuracy of robot between real robot and software?
You haven’t specified what kind of deviation you have. If you do, or have some pictures its maybe more easy to help you. But my thoughts on this so far:
As I understand it , Visual Component uses an generic motion controller, not a specified for Yaskawa. Because of this you have different robot behaviour in space-time-relations. Pure cinematic positions should be the same (with typical sim2real gap).
There may also be some wrongly set reference coordinate systems.
Have you calibrated your Visual Components layout to the robot cell?
Whoever sold you your license should be able to help you with that - I suggest you contact them.
With good calibration you can get under 1mm of deviation without any problem.
