Robotic Design Analysis Based on Teleoperated Manipulator Data Collection

摘要

Extensive data collection was performed on a servomanipulator system (TeleOperator Systems SM-229) to determine the motion range and mechanical power usage of the manipulator under direct human control. More than 50 hours of various manipulation operations were performed while joint positions and motor currents were recorded. Reduction of these data yielded histograms of the manipulator usage patterns revealing areas where future manipulator motion ranges and drive systems could be optimized. This report develops a graphical representation of mechanical power usage that relates torque and velocity to the total usage time. Methods of interpreting this representation are discussed and generalized for use in analyzing robotic systems. The resulting technique will allow designers to reevaluate an operating system and determine how to improve that system's design. (ERA citation 10:044854)
