Ten-degrees-of-freedom double-mechanical-arm structure of old-age care robot

Abstract

The invention discloses a ten-degrees-of-freedom double-mechanical-arm structure of an old-age care robot, and belongs to the field of mechanical design and manufacturing. The double mechanical arms of the care robot comprise two single mechanical arms with the identical structure, wherein each single mechanical arm has five degrees of freedom, that is, a shoulder front-rear swinging degree of freedom, a shoulder left-right swinging degree of freedom, a large arm inside-outside rotating degree of freedom, a small arm ascending-descending degree of freedom and a manipulator ascending-descendingdegree of freedom separately, and the five degrees of freedom are driven by the respective motors to realize the movement of the part strictures separately; and the double mechanical arms have ten degrees of freedom totally. The double-mechanical-arm structure provided by the invention is reasonable and compact in overall layout; each selected motor has a high loading capacity, and is capable ofrealizing a high load; the overall structure dimensions of the care robot are coordinated with the proportions of human body, and the shoulder breadth, arm length and arm spread are proper; the operation process is simple; and in an operation process, mutual non-interference of running among the degrees of freedom is achieved, so that realization for the care of a carer for a cared person is facilitated.

Description

technical field [0001] The invention belongs to the field of mechanical design and manufacture, and in particular relates to a ten-degree-of-freedom double mechanical arm structure for an elderly care robot that can replace or assist a caregiver in caring for a care receiver. Background technique [0002] At present, in the research field of humanoid service robots, many countries are researching various distinctive robots, and each country has its own advantages. Japan has advanced robot technology, and the action of simulated human beings is the main direction of Japan's attack. The impact on the world in the future cannot be ignored; European countries mainly focus on medical services, while the main purpose of the United States is military use. Introducing robots into traditional rehabilitation nursing is a development trend in rehabilitation nursing. At present, robots have been applied to medical limb movement assistance, rehabilitation nursing and rehabilitation trai...

AI Technical Summary

Problems solved by technology

However, the existing elderly care robot manipulators are complex in operation, unreasonable in structure design, and incomplete in function. The structure of the manipulator is transmitted by a conveyor belt or a chain, and the load is relatively low, so heavy loads cannot be achieved. Assisting the caregiver to take care of the cared played a very limited role in the process of
