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.
