Abstract

The invention discloses a mechanical arm capable of carrying out tension detection. The mechanical arm comprises a driving module, a mechanical arm module, a plurality of driving ropes and a pluralityof tension sensors, wherein one end of each driving rope is fixedly connected with the mechanical arm module, and the other end of each driving rope is fixedly connected with the corresponding tension sensor, so that when the driving module drives the driving ropes to stretch out and draw back, the tension sensors are made to detect tension of the driving ropes connected with the tension sensors.According to the mechanical arm, the stress condition of the corresponding driving ropes are detected through the tension sensors, and in combination with the adjusting action of the driving module,the situation that the driving ropes are loosened or over-tightened is avoided.

Description

technical field [0001] The invention relates to the field of robots, in particular to a flexible mechanical arm. Background technique [0002] At present, a large number of high-efficiency and high-precision industrial-grade robots have been widely used in the fields of electrical, chemical, and mechanical manufacturing industries. However, traditional industrial robots cannot adapt to extreme Narrow and extremely dangerous working environment, such as pipe cleaning, etc. [0003] Compared with traditional manipulators, due to their inherent super-redundancy characteristics, flexible manipulators can realize the bending, telescopic, and torsion of multiple continuous parts, and their movement and operation capabilities in confined spaces are much higher than traditional multi-joint joints. Rigid link robot. In order to make the bending accuracy of the flexible manipulator more controllable, the existing flexible manipulator is usually connected by multiple joints in sequen...
