Design and analysis of a human-machine kinematic compatible robotic hip exoskeleton
摘要
Abstract
Current hip exoskeleton robots hinder natural human motion and limit human-robot collaborative movement range.A human-machine kinematic compatible robotic hip exoskeleton is designed to address these issues.The exoskeleton adopts an underactuated serial mechanism at the hip joint,utilizing a revolute-revolute-prismatic-spherical(RRPS)six-degree-of-freedom mechanism as the kinematic chain.Simultaneously,the human-robot coupled kinematic and dynamic models of the hip joint are established to validate joint motion ranges under human-exoskeleton collaborative movement,and the reference active assistive torque is derived.Furthermore,the control technology for the exoskeleton is investigated,including a phased recognition algorithm for human lifting motions and a human-robot collaborative control strategy.Finally,performance evaluation experiments are conducted on the exoskeleton.The experimental results show that the exoskeleton achieves 100%of the natural human motion range,and surface electromyography signals indicate a reduction of 8.4%and 6.14%in lumbar and hip muscle load respectively,confirming its excellent motion compatibility and effective assistive performance.关键词
