Rehabilitation　robots　are　playing　an　increasingly　important　role　in　daily　rehabilitation　of　patients.　In　recent　years,　exoskeleton　rehabilitation　robots　have　become　a　research　hotspot.　However,　the　existing　exoskeleton　rehabilitation　robots　are　mainly　rigid　exoskeletons.　During　rehabilitation　training　using　such　exoskeletons,　the　patient＇s　joint　rotation　center　is　fixed,　which　cannot　adapt　to　the　actual　joint　movements,　resulting　in　secondary　damage　to　the　patients.　Therefore,　in　this　paper,　a　tendon-driven　flexible　upper-limb　rehabilitation　robot　is　proposed;　the　structure　and　connectors　of　the　rehabilitation　robot　are　designed　considering　the　physiological　structure　of　human　upper　limbs;　we　also　built　the　prototype　and　performed　experiments　to　validate　the　designed　robot.　The　experimental　results　show　that　the　proposed　upper-limb　rehabilitation　robot　can　assist　the　human　subject　to　conduct　upper-limb　rehabilitation　training.
