Precision of Wrist Camera

tor_odigo

Hi,

What is the precision of the wrist camera? I'm working on a project where we need a tolerance of +/- 0,5mm when spot welding with a UR10e. Is this possible to achieve with the wrist camera? I can't seem to find any info on the precision in the manual.

Cheers,
Tor

Hi @tor_odigo,

Indeed, there is no "precision" specification per se in the documentation. 

For the UR10, the wrist camera's accuracy is +/- 3mm.

The accuracy spec factors in Calibration Error + Model Error + Locating Error + Picking Error.



There is, however, a precision spec for the Visual Offset feature of the Wrist Camera.

The worst-case position error found is:

+/- 1.5mm in X, Y, and Z
+/- 1° in Rx, Ry, and Rz

Hopefully, this answers your questions. Should you have any further questions, please do not hesitate to reach out and I'll be happy to assist.

Kind regards,
