The invention discloses a rope-driven robot. The rope-driven robot comprises a static platform and a movable platform arranged above the static platform, wherein an upper connecting rod and a lower connecting rod are connected between the static platform and the movable platform; three sets of rope-driven branched chains are arranged on the static platform in a circumferential array mode; each rope-driven branched chain comprises a transmission rope, a motor, a take-up wheel disc, a supporting frame, a first grooved wheel, a telescopic rod and a second grooved wheel; the motors are arranged onthe static platform and drive the take-up wheel discs to rotate; the first grooved wheels are rotationally connected to the supporting frames; the second grooved wheels are rotationally connected tothe telescopic rods; the transmission ropes sequentially bypass the take-up wheel discs, the first grooved wheels and the second grooved wheels; the two ends of the transmission rope in any set of rope-driven branched chain are connected to the two sides of the movable platform through steering structures correspondingly; and each steering structure comprises a baffle, a connecting rod and a thirdgrooved wheel. According to the rope-driven robot, non-redundant driving is achieved in driving, and the rope-driven robot has the characteristics of being simple in structure, large in working spaceand small in motion inertia.
