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,


    Marc-André Baron
