Flexible operating arm used for service robot

Abstract

The invention discloses a flexible operating arm used for a service robot. The operating arm comprises joints and connecting rods, wherein each connecting rod is a flexible connecting rod, such as a shaped hose, which can be bent into a certain shape arbitrarily and keep a corresponding shape in a three-dimensional space; the length and the size of each connecting rod when being curved are basically steady, and each connecting rod after being curved has a certain support force. The operating arm has a small number of joints, but owns multiple joint operating arms, so that abundant working space is owned, and tasks which only can be finished by a multi-freedom operating arm can be carried out by the flexible operating arm. Furthermore, the operating arm has multiple purposes, and can multiplex the same operating arm to adapt to various environments and tasks. In addition, the operating arm has negative flexibility, and can reduce damage to external people and objects, so that safety of a service object is guaranteed. Compared with the traditional operating arm, the flexible operating arm is more flexible, lighter and safer; the cost of the flexible operating arm is reduced greatly; and the flexible operating arm is more suitable to be applied in the fields such as domestic services and medical facilities.

Description

technical field [0001] The invention relates to a robot operating arm, in particular to a flexible robot operating arm used in the service field. Background technique [0002] Manipulator arms are well known as a common robotic mechanism. The operating arm can realize various functions such as welding, grasping and touching, so the operating arm is widely used in industrial production fields such as automatic assembly, painting, handling, and welding. Most of the current operating arms are used in industrial production. Although they have advantages such as high precision, industrial operating arms are bulky, have low flexibility, hard shells, and high costs. However, when the service object is human, it is often desired that the manipulator arm is more flexible, lighter, safer, and relatively low in cost. Therefore, ordinary industrial manipulator arms cannot meet the needs of household services, medical facilities and other fields. Specifically: [0003] Ordinary manip...
