In order to solve the problem that traditional manipulator is difficult to detect,maintain and clean in unstructured narrow space,a rope driven super redundant manipulator was designed and its mechanics performance was analyzed.The whole mechanical arm was composed of a driving part and a mechanical arm,and a telescopic rod was installed at the root of the mechanical arm to make it move in the horizontal direction;the friction between the rope and the connecting rod was reduced by installing pulleys inside each connecting rod.ADAMS was used to analyze the joint and rope transient stress,the static theory analysis of the rope was carried out through the moment balance method,and the stress of the rope at any angle of each joint was calculated to verify the simulation results.ANSYS Workbench was used to check the strength of the joint with the maximum stress,and its stress met the material strength requirements.
