Targeting the future planetary exploration,a conceptual design model was proposed for a hard space suit with redundant degree of freedom(DOF).Meanwhile,the conceptual design of a hard hip joint was carried out.The motion analysis and geometry modeling were conducted.The virtual prototype technology was used in designing the conceptual model of space suit.First,a design scheme of space suit was determined and its DOF was distributed into respective joints including the shoulder joint,the elbow joint,the wais...
