Trouble Ensuring Precise Alignment With the Robot

Technical Questions
1

Hello UR community,

I’m currently working on a project with a Universal Robot, and I’m encountering an issue with the calibration process. Specifically, I’m having trouble ensuring precise alignment between the robot and its work environment. Does anyone have any tips for improving the accuracy of calibration?
I also check this : https://forum.universal-robots.com/t/precise-alignment-calibration-to-external-feature/7657/4snowflake
But my problem is not solved. Please guide me in this.

Thanks in advance!

You’re talking as if you have a calibration process implemented already? Can you elaborate on your method of calibrating? :slight_smile:
Also, tell us about your whole setup; is it also an AGV? What’re your calibration needs?

I’m working on a high accuracy aligner (Selfie Aligner)
Here is a couple of short videos with an early demonstration setup
This demo model is only optimized for accuracy. Not for speed
