Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as Figure 1 to Figure 3 As shown, the robot of the present invention is composed of a controller 4, a battery 5, a sensor, a handrail 13, a keyboard 2, a drive wheel 9, a universal wheel 6, a drive motor 8, etc., wherein the sensor includes a pressure sensor 11, a slip sensor 1 , distance measuring sensor 10 and road condition sensor 12. The pressure sensor 11 measures the pressure of the upper hand on the armrest bar 13 to the robot, and the slip sensor 1 measures the relative motion between the hand of the elderly and the armrest of the robot. After the slip signal and pressure signal are collected by the corresponding sensors, they enter the controller for feature extraction and discrimination. The discrimination results are the movement tendency and fall tendency of the elderly. According to the result of the discri...

Abstract

The invention discloses a wellbeing and friendly walk-helping robot comprising a pedestal, a universal wheel, a driving wheel, a bracket and a handrail. The universal wheel and the driving wheel are arranged on the lower part of the pedestal. A battery is arranged on the pedestal. The driving wheel is provided with a driving device controlled by a control device. The signal input of the control device is connected with a sensing device. The control device comprises a keypad arranged in the middle of the handrail and a DSP-based controller arranged on the battery. The sensing device comprises pressure sensors symmetrically arranged on both ends of the handrail, slide sensors arranged on three surfaces and both ends of the handrail and a distance measuring sensor arranged on the middle and rear part of the handrail. The driving device has two driving motors installed on the left and the right driving wheels respectively. The robot perceives the dynamic relation of the old and judges whether the old tend to fall down by the slide sensors and the pressure sensors arranged on both sides of the handrail. And the controller processes information and gives instructions to a driving system. The driving system used as a performer changes the motion state of the robot to help the old.

Description

technical field [0001] The invention relates to a service robot, in particular to a welfare-friendly walk-aid robot for the elderly. Background technique [0002] All countries in the world generally attach great importance to the research of service robots, and have achieved remarkable results. In 1987, a prototype rehabilitation robot developed by the British enabled an 11-year-old boy with cerebral palsy to eat independently. The United States, Canada and France have successively produced service robots that can grab the required items from the corresponding item shelves according to the operating requirements in a known environment. In October 2004, Japan's SECOM Corporation released the self-care robot "SECOM Lift" for the nursing staff, which can help the nursing staff transfer from the bed to the wheelchair or from the wheelchair to the bed alone. [0003] my country's research and development in the field of service robots started relatively late. In 1995, Tsinghu...
