Abstract

The invention discloses a passive decoupling mechanism for joint movement of a tandem rope-driven manipulator, and overcomes the problem of joint movement coupling of the tandem rope-driven manipulator. The passive decoupling mechanism comprises a base system, a decoupling module, a first decoupling rope, a first arm system, a second arm, a second decoupling rope, a second driving rope and a firstdriving rope; the base system comprises a second driving wheel, a first driving wheel and a base plate; the first arm system comprises a first active wheel, a second active wheel, a round shaft and afirst arm plate; the decoupling module is mounted in a rectangular groove of the base plate through a guide rail thereof; the first arm system is mounted in a right polish through hole on the base plate through the lower end of a small-shaft section of the first driving wheel; the second arm is mounted at the right end of the first arm plate by adopting a key and the round shaft; the first driving rope is sleeved in a groove above the first driving wheel and the first active wheel on the base plate; and the first decoupling rope, the second decoupling rope and the second driving rope seriallyconnect the base system, the decoupling module and the first arm system.

Description

technical field [0001] The invention relates to a mechanism for passive decoupling motion, more precisely, the invention relates to a passive decoupling mechanism for the joint motion of a serial rope-driven manipulator. Background technique [0002] Since the first manipulator developed by United Control Corporation in 1958, the serial manipulator has been developed for 60 years. The serial manipulator has gradually developed in two directions: one is miniaturization and the other is large-scale. In the development of large-scale development, the manipulator pursues a higher load capacity; in the process of miniaturization, the manipulator pursues a slimmer body shape in order to work in a narrow working space. Many researchers have proposed methods to reduce the size of the manipulator by using mechanisms such as ropes, gears, and connecting rods as power transmission media. Using the rope as the power transmission medium can greatly simplify and reduce the kinematic join...
