die 100g stammen aus dem obigen Link, hier hat jemand genau danach gefragt, und geantwortet hat jemand, der den Arm besitzt und getestet hat:

(edit, die 3A scheinen sich tatsächlich auf 1 NEMA 17 Stepper zu beziehen)
Ich weiß ntl nicht, ob das der Weisheit letzter Schluss ist, aber ich habe noch keinen Bericht gefunden mit annähernd 1kg oder sogar mehr, die jemand wirklich (nicht nur theoretisch) erreicht hat.I just finished mine, so I can tell you: The payload is unfortunately quite low. The reason is that the Stepper on the last joint (a NEMA 17) is a bit too weak. Even using it at 3Amps full step, which is much more than the recommended current of 1Amp is not enough to lift more than 100g. I’m considering reworking on the 3D files in order to add a gearbox to this motor, it doesn’t need much speed, what it needs is torque. There is another problem about the design of the rotating arm, (the joint which is just before the one I just mentionned, which has the motor completely enclosed inside the forearm) which could be better. On this joint, I already modified my plastic part to put a bigger motor but it still doesn’t seem to be enough and I’m sometimes missing stepd, without any load. These two parts could be improved. The bottom half of the robot is quite powerful, especially since I’ve put much bigger motors than recommended. I hope the team of Moveo, which did a great job so far already, will investigate into these problems and come up with a better version. But to be fair, they did the biggest part of the job, the tweaking is up to us ��
