Hi Pros,I had several discussions with colleagues, clients and other UR users about the accuracy of the UR robots. When we are programming pick and place applications where the robot is always picking for the same positions, the repeatability of the robot is fine. However, some people trying to move the robot around using specific distances that are sent to the robot. For example, there are some people trying to create some parametric motion. Something like giving the dimension of a rectangle and have the robot move along the edge of the rectangle. Also when using vision systems, the vision system is sending distance offset from a known origin frame. In these cases, when you ask the robot to move let's say 1000mm, it may actually move 1000mm+-5mm. I discuss this with some pros and they mentioned that calibrating the UR would help. However this calibration requires some serious work. So before suggesting this option I was wondering if some pros did try this out and if they can put some numbers on the accuracy improvement of either calibration methods suggested by UR? For those who have not heard about UR calibrations, here is a link to the UR support website where you will find info on this.
