Wheelchair with object-taking function and control method thereof

Abstract

The invention discloses a wheelchair with an object-taking function and a control method thereof. The wheelchair includes an electric wheelchair, a humanoid robotic arm and a wheelchair control system, and the wheelchair control system includes an eye tracker, a microcomputer, a camera, and a microphone. The method for controlling the object taking includes the steps of: 1. the disabled person sits in the electric wheelchair and wears the eye tracker; 2. the disabled person firstly speaks to the microphone to tell what item he wants to take, and then looks at the position where the wheelchairis to arrive; 3. the wheelchair control system controls the position of an eye gaze point that the electric wheelchair needs to reach from the current position to the wheelchair; 4, the item that thedisabled person wants to take is obtained, and the center coordinate of the target information is determined; and 5. the wheelchair control system controls the humanoid robotic arm to reach the position of the item and take the object. The wheelchair has novel and reasonable design and high control precision, so that the electric wheelchair and the humanoid robotic arm can automatically assist thedisabled person to take things, which greatly facilitates the life of the disabled person and has strong practicability.

Description

technical field [0001] The invention belongs to the technical field of intelligent control, and in particular relates to a wheelchair with an object retrieval function and an object retrieval control method thereof. 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 ...

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
