A retrieval control method for a wheelchair with retrieval function

Abstract

The invention discloses an object retrieval control method for a wheelchair with an object retrieval function. The wheelchair with an object retrieval function includes an electric wheelchair, a humanoid mechanical arm, and a wheelchair control system. The wheelchair control system includes an eye tracker, a microcomputer, Camera and microphone; the fetching control method includes steps: 1. The disabled person sits on the electric wheelchair and wears an eye tracker; 2. The disabled person first speaks to the microphone what item they want to fetch, and then gazes at the position where the wheelchair will reach ;3. The wheelchair control system controls the electric wheelchair from the current position to the position of the eye gaze point that the wheelchair will reach; The system controls the humanoid robotic arm to reach the position of the picked item and pick it up. The invention has a novel and reasonable design, high control precision, enables the electric wheelchair and the humanoid mechanical arm to automatically assist the handicapped to fetch objects, provides great convenience for the life of the handicapped, and has strong practicability.

Description

technical field [0001] The invention belongs to the technical field of intelligent control, and in particular relates to an object retrieval control method for a wheelchair with an object retrieval function. Background technique [0002] The wheelchair is an important tool for rehabilitation. It is not only a means of transportation for the physically disabled, but more importantly, it enables them to perform physical exercises and participate in social activities with the help of wheelchairs. The use of wheelchairs by the elderly and the disabled has become very common. The advancement of modern technology has also made wheelchairs develop greatly. There are electric wheelchairs, GPS electric wheelchairs, special wheelchairs, sports wheelchairs and other multifunctional wheelchairs. The emergence of electric wheelchairs provides people with automatic walking, massage, height adjustment and climbing. The slope function meets the needs of more people. There has been a lot of...

Problems solved by technology

The first one, Zhou Tingting's master's thesis of Hangzhou Dianzi University in 2014, "Research on Controlling Electric Wheelchairs Based on Intentional Eye Movements", in which the eye movement control is used to identify the direction of eye movement by collecting eye electrical signals , not fast and convenient enough; the second one is Yuan Chunxing's master's thesis "Natural Human-Computer Interaction Based on Eye Movement" of the 2015 National University of Defense Technology. In this paper, the wheelchair can be controlled by eye movement within a short distance. When the location is far away, the wheelchair cannot be allowed to automatically perform path planning and autonomous movement

[0005] In the prior art, there is still a lack of wheelchairs with reasonable design, strong practicability, and good use effect with the function of fetching objects and their fetching control methods
