Coordination Evaluation of Exoskeleton Seat Combined with Motion Capture
Exoskeleton seats are becoming more and more popular in industry,but the coordination of some exoskeleton seats still needs to be improved.In order to comprehensively evaluate the coordination of the exoskeleton seat under dynamic and static con-ditions,12 subjects simulated the dynamic and static tasks of the express assembly line operation with and without the exoskeleton seat.The motion data of hip,knee and ankle joints were collected using optical motion capture equipment,and SPSS was used to perform Wilcoxon rank sum test.Finally,subjective evaluation data were collected through a five-level Likert scale questionnaire to verify the consistency of subjective and objective results.The results showed that in the dynamic walking task,the knee joint angles of both legs decreased,and the speed and acceleration of the hip,knee and ankle joints also showed a downward trend,espe-cially when walking fast:in a static sitting posture,the hips and upper thighs are easy to produce discomfort,and it is easy to fall when you adjust your sitting posture.In conclusion,the overall coordination of the exoskeleton seat is poor,which restricts the move-ment of each joint:it is prone to instability and discomfort when assisting the sitting posture.The results of subjective and objective data are consistent.This method can effectively quantitatively evaluate the coordination of exoskeleton seats and provide a quanti-tative reference for further optimization.
