ABSTRACT:
A method and system for wear testing a seat by simulating human seating movement utilizing a robot and a robotic human body simulator mounted at a distal end of an arm thereof wherein a seat back surface as well as a seat bottom surface are wear tested without the need of video tape interpretation by a user of the system. Measured data is obtained by measuring 3-D locations of parts of a human during ingress of the human onto a calibration seat and egress of the human from the calibration seat. The measured data represents locations of the parts of the human. A control program is generated on the measured data by transforming the measured data to control program targets. Load and/or pressure feedback is provided for control program verification. The simulator includes a plurality of drives which receive drive control signals from a robot controller for moving a trunk and thigh parts of the simulator relative to and independent of one another to test wear characteristics of the seat bottom surface and the seat back surface of the seat under test for a plurality of cycles.
