Problems solved by technology

The disadvantage is that another assistant besides the robot is needed to assist the robot to operate, and the robot cannot be fully autonomous
The disadvantage is that it is difficult to distinguish whether the heart rate change is completely caused by the incorrect action of the machine or caused by other external interference factors simply relying on the heart rate change as the control standard.

Abstract

The invention relates to a behavior safety control method of a moving riding nursing robot. The moving riding nursing robot is moved and ridden through a front hoop type. The method comprises the steps of studying the process of the motions that the robot is moved and ridden, analyzing posture motion parameters of the robot and the human body in each motion cycle, obtaining the function relation of the posture of the moving riding nursing robot and the human body posture, namely change conditions of the gravity of the human body, further obtaining a computing model of robot postures and human body gravity distribution, with the computing model being a reference standard, in the moving riding nursing type robot actual motion process, and through the combination of a human body brain wave signal and a grip force handle force signal, monitoring a pressure value of a support position in real time, when an unreasonable posture is detected, by comparing an error between an actual value and a computing model theoretical value, timely adjusting a motion posture of the robot, so that a safe and comfortable nursing motion effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of nursing robots, and in particular relates to a behavioral safety control method for transferring a nursing robot. Background technique [0002] With the continuous development of society, the degree of population aging is accelerating. Taking care of the daily life of the elderly has become a difficult problem for every family in today's society, especially for the elderly with physical diseases. The emergence of transfer care robots will greatly relieve the work pressure of elderly care. Migration care robots use robots to assist the elderly with limited mobility in their daily activities. Through the support of the robot's own foot pedals, chest rests, and underarm armrests, it helps the elderly to transfer from the bed to the wheelchair or other designated target positions. [0003] At present, most of the research in the direction of human rehabilitation nursing is about the rehabilitation training...
