Manipulator system and working method for assisting upper limb disabled people to eat and drink

Abstract

The invention discloses a manipulator system and a working method thereof for assisting disabled persons with upper limbs to eat and drink. The demand signal is transmitted to the controller through the command input device; the controller controls the rotation of the turntable, and the feeder is rotated to the working position close to the manipulator; then, according to the voice command issued by the recipient, the controller controls the manipulator to realize the grabbing of the special feeder Actions. The present invention rationally combines the teaching and reproduction control method with the human-computer interaction control method, which can not only solve the problem that the teaching and reproduction operation of the robot cannot adapt to the change of the work object, but also effectively solve the problem that usually only human-computer interaction is used. Type control method operation will make the shortcomings of numerous operating instructions, and it can also make full use of the design of the special feeder to greatly reduce the requirements for the complexity of the operation.

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.
