I hope to measure our RV-M1 robot's accuracy utilising a CMM and calibrate it accordingly using ISO 9283 definitions.
Would anyone know the best method of doing this?
Thanks,

Nobody here has ever done anything like it.
I imagine its a long, labourious procedure as every combination of every joint position will have different rigidity.
eg, With all joints pointing upwards, turning just the wrist will show pretty good accuracy / repeatability as the load is direct through all the joints
With the wrist pointing out sideways it'll be a completely different matter as the load forces act on the the motor/belts/chains as well.
Good luck
