TM Cobot Payload Derating
Published October 5th, 2023 by Arlo D'Cruz
Introduction The TM series collaborative robots each have a payload rating, however they are derated as the payload moves further from the flange. The maximum allowed payload of the robot arm is related to its center of gravity offset, which is defined as the distance from the center point of tool flange to the payload’s center of gravity. The tool
