I have an idea to calibrate the robot by correcting the DH parameters. The way I envisioned was to calibrate the robot by modifying the DH parameters in the ‘urcontrol.conf’ file of my robot setup folder on the OS? Or Is there any other way to correct the DH parameters of the robot?
The DH parameters in URControl.conf is the generalized parameters of any robot of that size.
In the file calibration.conf you will find a set of corrections, that apply to this particular calibrated robot.
Note that all UR robots are absolute calibrated from the factory.
Also refer to the calibration manual on the Support Site.
