Six-degree-of-freedom bionic mechanical arm

Abstract

The invention provides a six-degree-of-freedom bionic mechanical arm. The bionic mechanical arm comprises a shoulder joint, an elbow joint and a wrist joint which are connected in sequence, wherein alarge arm part is arranged between the shoulder joint and the elbow joint, a forearm part is arranged between the elbow joint and the wrist joint, and a bionic palm is arranged at the tail end of thewrist joint. Six rotating devices are arranged to achieve the six rotating degrees of freedom of the bionic mechanical arm respectively to simulate a series of motions of a human arm such as the opening of shoulders, the swing and self-rotation of the large arm part, the swing and self-rotation of the forearm part, and the swing of the palm, and all motions do not interfere with each other. The bionic mechanical arm has the advantages of high control precision, high motion freedom degree, and compact structure. Artificial skin is arranged on the outer side surfaces of the large arm part and the forearm part, therefore the load borne by the large arm part and the forearm part in contact with a human body can be detected and fed back in real time, and the safety performance is improved.

Description

technical field [0001] The invention belongs to the technical field of robots, and more specifically relates to a mechanical arm, especially a six-degree-of-freedom bionic mechanical arm for nursing robots. Background technique [0002] With the aging of the population, the shortage of medical personnel is becoming more and more serious. During the nursing process, patients need to be transferred frequently, such as picking up a bedridden patient and transferring it from the bed to a wheelchair. This process requires the medical staff to have great strength and even the cooperation of multiple people. Serving these elderly patients requires a huge amount of work. Time and energy, this process not only seriously affects the working status of nursing staff, but also directly affects the quality of service to patients. In terms of hospital care, human resources are becoming more and more tense, especially when facing more and more patients. It seems powerless. Therefore, the ...

During the nursing process, it is necessary to transfer patients frequently, such as picking up a bedridden patient and transferring them from the bed to a wheelchair. This process requires the medical staff to have great strength and even the cooperation of multiple people. Serving these elderly patients requires a huge amount of work. Time and energy, this process not only seriously affects the working status of nursing staff, but also directly affects the quality of service to patients. In terms of hospital nursing, human resources are becoming more and more tense, especially when facing more and more patients. seem powerless
