Mechanical arm system assisting person with upper limb disability in dining and work method of system

Abstract

The invention discloses a mechanical arm system assisting a person with upper limb disability in dining and a work method of the system. The system comprises a mechanical arm, an instruction input device, a rotating disc system, a plurality of special feeders, a work platform, a mouth positioning device and a controller; request signals are transmitted to the controller through the instruction input device; the controller controls a rotating disc to rotate, the feeders are rotated to the work position close to a mechanical arm, and according to voice instructions sent out by the aided person, the controller controls the mechanical arm to achieve action of special feeder grabbing. The teaching reappearing control method is reasonably combined with the man-machine interaction control method, the problem that robot teaching reappearing operation cannot adapt to changes of a work object is solved, the defect that generally, only the man-machine interaction type control method is used for operating, and operation instructions are tedious is overcome effectively, and design of the special feeders is fully used for greatly reducing the requirement of operation action complexity.

Description

technical field [0001] The invention relates to a system structure design and a working method of a manipulator for helping the elderly and the disabled, especially a type of robot technology application for assisting people with disabled upper limbs to eat and drink. Background technique [0002] At present, manipulators for assisting the elderly and the disabled in the catering category mostly use human-computer interactive control methods with partial intelligent perception (such as voice recognition, image recognition, object positioning, etc.). Since there are many types and shapes of catering items that need to be operated, the operation methods required in the process of feeding the recipients will vary greatly, and it is difficult to use a certain conventional method to accurately pick up various forms of food for the recipients with feeding. [0003] For example, a meal-assisting robot disclosed in Chinese Patent Application No. 201410678906.9 has a mechanical stru...

AI Technical Summary

Problems solved by technology

The meal-assisting robot can meet the limited styles of catering items. Although the manipulator is equipped with spoons and forks, it is not easy to pick up food, and it cannot guarantee accurate and stable feeding. Feeding is also inefficient

[0004] Including other manipulators with similar functions, their common deficiency is that on the one hand, it is necessary to continuously issue various complicated instructions during operation to feed different types of catering items into the recipient population, making the operation process very complicated and difficult. On the other hand, general-purpose feeding utensils cannot meet the needs of feeding different food styles.
