Precise alignment/calibration to external feature


My UR16e is mounted on an AGV. The AGV can deliver ±1mm positioning accuracy with respect to a target stationary docking platform. I need to position the robot tool with reference to that platform with ±0.3mm and ±1deg accuracy. I looked up the Robotiq wrist camera tool but it can only achieve ±1.5 mm accuracy.
What can I do to get down to the required accuracy through code (without human supervision)?

Thank you very much!

Hi @dimitar,

I am not aware if any of the UR+ optical sensors will meet your accuracy requirement. With a mechanical reference fixture, you should be able to make a routine that can achieve the high accuracy.
