    construction and used components will define maximum stress arm can endure. they are selected based on requirements for specific model. this can get you pretty good info what may be possible with specific design. normally if you gradually increase load you will reach point where system is not able to react as expected. then you can do stress tests to confirm that robot system is able to operate in certain condition over long time without overheating, premature wear etc. The actual rating you list in specs is data you come up with - it is compromise between performance and reasonable service life.

    Thanks a lot, wise words! Could you or other pals provide appropriate sources from which I could read more on the subject? On topics like robot building, load testing, and stress testing. And other answers are more than welcome. It would also be useful to look at this in more detail.

    In its simplicity, how can a robot’s handling capacity or maximum payload be determined? For example, the ISO 9283 standard focuses only on the definition of accuracy and repeatability, and there is no information on testing or defining a payload. Scientific articles mainly focus on determining the maximum payload in a given trajectory. What if the trajectory is unknown? Clearly related to the definition of the payload, the torque constraints of the actuators and other considerations are the dynamic and kinematic modeling of the manipulator. And stability in wheeled manipulators. I would be grateful if you could provide information and proper sources for defining and testing your maximum payload. I am not yet an expert in the field.
