Pension assisting intelligent wheelchair with continuous mechanical arm

Abstract

The invention discloses an intelligent nursing assisting wheelchair with a continuous mechanical arm, which comprises the continuous mechanical arm, a movable wheelchair, a mechanical arm driving module, a wheelchair driving module, a remote control module and a control module, the device is of a continuous structure jointly composed of a plurality of springs, a plurality of basic units and six transmission ropes. A user sends data to the control module by operating the remote control module, the control module sends instructions to the mechanical arm driving module and the wheelchair driving module, then a servo motor and an electric motor are driven, double-machine collaborative operation of a mechanical arm and a wheelchair is achieved, and therefore the auxiliary grabbing task is completed; the functions of assisting a user in opening and closing doors and windows, massaging the body, taking and placing articles and the like are achieved. The method has the advantages of adaptability to unstructured environment, practicability and man-machine interaction safety, and is suitable for family type old-age care auxiliary tasks.

Description

technical field [0001] The invention relates to the technical field of wheelchairs, in particular to an old-age assistant intelligent wheelchair with a continuous mechanical arm. Background technique [0002] With the development of robotics, home service robots have gradually become a research hotspot in robotics, which can help reduce the burden on society and families to a certain extent. A wheelchair robot is generally composed of an intelligent wheelchair and a mechanical arm installed on the wheelchair. It is used to help the elderly with difficulty in physical movement to complete part of their daily life operations. It is a service robot that can provide auxiliary assistance. The user can directly control the wheelchair robot, grab the designated object at the designated position, and complete auxiliary actions. Therefore, the wheelchair robot is not only a mobile auxiliary tool, but also a life assistant that can truly solve the life problems of the elderly. [00...

AI Technical Summary

Problems solved by technology

At present, traditional pneumatic and hydraulic continuous manipulators usually require a large number of auxiliary equipment such as pumps with sufficient flow, controllers and air pipes, which are not convenient for use on wheelchairs; and the preparation of new materials such as memory alloys and dielectric elastomers Complicated, expensive, and lack of universality

[0004]At present, the wheelchair robot is composed of an intelligent wheelchair and a rigid mechanical arm, which is easily limited by its degree of freedom, resulting in the need to frequently alternately adjust the position of the wheelchair and the mechanical arm when grasping objects posture problem
