Embodiment

[0068] The present invention solves three problems: one is to provide real-time positioning for the blind in a complex indoor environment and plan the optimal route from the starting point to the destination for them; the other is to provide guidance for the progress of the blind through the movement of the robot; The third is to enhance the human-computer interaction experience by adding vibration interaction handles and voice interaction functions.

[0069] Its main features are as follows:

[0070] Based on the above-mentioned first problem "providing real-time positioning for the blind in a complex indoor environment and planning the optimal route from the starting point to the destination for them"; the present invention is equipped with a Jeston Nano processor (blind-guiding decision-making layer) and a single-line laser radar on the robot. , IMU; the ROS control framework is deployed on Jeston Nano, which mainly includes SLAM service system and blind guide service stack...

Abstract

The invention discloses an indoor blind-guiding robot. The robot terminal collects laser ranging data, destination data, pose data, surrounding information data and odometer data, and collects the collected laser ranging data, destination data, position Attitude data, surrounding information data and odometer data are uploaded to the blind-guiding decision-making layer, and respond according to the control information of the blind-guiding decision-making layer, and move the robot to provide guidance for the progress of the blind; the blind-guiding decision-making layer includes autonomous map building , autonomous positioning, intelligent blind guide, human-computer interaction four functions. The present invention introduces ROS and SLAM; at the same time, voice interaction and vibration stick are added to improve user experience. It can assist the blind to reach the destination faster and better through composition, relocation, path planning and motion control; the integrated vibration interaction The handle and voice interaction function make the human-computer interaction experience better.

Description

technical field [0001] The invention relates to the technical field of service robots, in particular to an indoor blind-guiding robot. Background technique [0002] There are 5 million blind people in our country, and there are millions of people with low vision. This group of figures ranks first in the world and is increasing every year. The expansion of visually impaired groups has brought about an increase in the market demand for blind guide equipment; not only that, but with the continuous improvement of urban construction, people's living environment is also changing, and traditional blind guide equipment can no longer meet this change. At present, research work on aids for the blind has been carried out in various countries around the world. The research focuses on the research of walking aids such as walking sticks, wearable walking aids, and mobile walking aids. [0003] As early as 2010, Japan developed an electronic blind guide stick, which uses ultrasonic sensor...
