Wearable blind assist robot mechanism accord with ergonomic

Abstract

The invention discloses a wearable blind assist robot mechanism accord with ergonomic. The mechanism achieves map construction and real-time robust positioning and navigation by using a camera, a depth camera, a laser radar, an inertial navigation device and the like. The two-way voice interaction between a robot and a blind person is achieved through a voice interaction structure, and a power supply and calculation structure provides power supply and related calculation functions for the entire robot. The mechanism combines an ergonomics theory, adopts a wearable blind assist robot design method, and makes the weight distribution of the blind person uniform; a multifunctional blind cane design idea that a laser lightning method is combined with a blind cane is adopted, real-time recognition of a ground road condition is achieved, and the safety of the blind person walking is improved; a method of two-way voice interaction and vibration bracelet interaction overcomes the defect of lowhuman-computer interaction reliability of the blind person in a noisy environment.

Description

technical field [0001] The invention relates to the field of robot research and engineering, in particular to an ergonomic wearable blind-assisting robot mechanism. Background technique [0002] For the visually impaired, how to master the way and characteristics of walking is an important part of daily life. The visually impaired can rely on certain auxiliary facilities, such as traditional blind sticks, electronic blind sticks that add sound waves to detect obstacles, and others Navigation equipment for the blind and so on. But the vast majority of visually disabled people feel that the auxiliary facilities that can be provided at present can't actually meet their activity needs, and they can't provide users with the correct path and avoid obstacles. [0003] Almost all visually impaired people hope that there is an auxiliary navigation device that can make them feel convenient and safe on the road just like normal people. [0004] The current blind aids mainly include w...

AI Technical Summary

Problems solved by technology

[0004] The current blind aids mainly include walking sticks, mobile blinds, wearable blinds, etc. Walking sticks are the most common blind aids, due to their simple structure and functions. Single, which greatly limits the mobility and range of activities of the blind; mobile assistive devices are mainly aimed at the elderly. Although they are powerful, they are not very adaptable to most blind people due to their large size; The type assistive device has the characteristics of flexible structure and diverse functions, and is an effective solution for blind-assisting robots.

[0005] A blind-assisting robot that can satisfy the visually impaired should have comprehensive and accurate perception of the environment, reliable and stable positioning and navigation, effective human-computer interaction processing, etc. However, there are few blind-assisting robots that meet the above needs under existing conditions
