Voice blind guiding robot with multiple sensors based on radio frequency identification and route planning method

Abstract

The invention relates to a voice blind guiding robot with multiple sensors based on the radio frequency identification (RFID) and a route planning method. The robot comprises a three-tier car body and a navigation handle, wherein the top tier of the car body is provided with a cloud deck with a handspike and an RFID module, the middle portion of the car body is provided with an obstacle avoiding sensor and a controller, the bottom tier of the car body is provided with an underpan, and the underpan is provided with a driving wheel, an omni-directional wheel, a motor, a motor driver, a storage battery pack and a power supply switching module. The method is characterized in that the indoor environment information is obtained through the RFID module, and the blind guiding robot collects the signal intensity between the environment and the radio frequency tag through the RFID module, obtains the coordinates of the target point in the two-dimensional array, and adds the initial point to the opening list, and searches the lowest point of the f-value in the opening list and regards the lowest point as the current point, switches the current point to the closing list, saves all the points without the need of detecting again in the closing list, and judges whether the opening list is empty, and judges whether the target point is added into the opening list. The device solves the problem of the human-computer interaction.

Description

technical field [0001] The invention relates to a blind-guiding device, in particular to a radio-frequency identification-based multi-sensor voice blind-guiding robot and a path planning method, which are highly practical, widely applicable, reliable and safe, and are suitable for blind people. Background technique [0002] Visual impairment is a disease that seriously affects the quality of human life. There are about 140 million visually impaired people in the world. Among them, 45 million people are blind, and on average, a blind person is born in the world every 5 seconds. There are nearly 13 million visually impaired patients in my country, including about 5.5 million blind people, and the number is increasing by 450,000 every year. For most blind people, the main reason that affects their quality of life is that they cannot walk freely, and they cannot avoid obstacles in the environment as flexibly as normal people. With the rapid development of robot technology, th...
