UP50 Measure its own payload

[robwright]

I'm aware the UP50 has a payload capacity of 50kGs, however the material handling payload I have attached has a drawing weight from the designer of 48.14kgs and the robot has suffered premature wear of the splined output shaft of its R-Axis. I am aware of some teaching issues that may have accelerated this wear, but I was wondering if its possible for the robot to auto-calculate its own payload weight to disprove the naysayers.

Many thanks in advance for any help,

have you factored the moment of inertia and the center of gravity on the payload?
I bet your overloaded.

Well the auto calculate feature was introdouced on late model XRC's so it really depends on your software version.

Even still though, it is not 100% accurate and I find it tends to over-estimate the weight.  So, it might actually show up at 55kg, which would only support your "naysayers"
