Hi.. I'm using gp25 motoman with yrc1000 robo and my teaching points are all changed after robo collided with the machine.
I need to know.. Why and is there a way to get my position in the robo back.

Hello, after the colision, the robot shouldn't changed the positions. In which way the points are all changed? The points changed the locations?

If you have any backup before the collision you can compare with the actual backup in order to see what it is different.

I dont have experience with the motoman robots, only with Kawasaki, but i had one case where the robot was loosing the positions. The problem was from the encoder values from the motors. I had to do the zeroing for the robot and re-teach the points again.
