How to calculate z value in srs staubli ?

Hi,

There could be multiple different reasons for that to happen,

1- The SRS tool and the real robot tool are different, please select the correct tool on SRS by navigating to it and right click and select as TCP

2- There is no clear answer, you need to look at the programs and try to understand how the robot gets the vision position. Any change of sharing a backup?

3- Again, it could be something inside the program forcing the point positions, once you change it on the pendant, and if you save, they should be persistent unless there is something in the program to change the value back.

1- why in srs 3d software the z axes decrement when the robot move down while in the real robot the z axes increment when the robot move down?

I'm agree with EIEsgalho. control the actual Frame and the actual tool...

2- How can i send a z of the picking point to the robot ? the z axes not start from a origin (0

On a Stäubli robot, the reference frame (World) is not on the floor but at the height of shoulder.

3-when I teach the points from the pendant are they persistent when the application is restarted?

When you teach or modifie a point, you change it in the ram of the controler. If you want to keep the modifications after a switch Off/On, you need to save the application in the rom (disque)... If the value is forced in the program you need to change the program...

Have a good day !
