Embodiment Construction

[0035] The present invention will be further explained below in conjunction with the drawings.

[0036] The present invention relates to a multi-sensor voice guidance robot based on radio frequency identification technology. The blind guide robot includes a car body. The car body adopts a layered structure. The uppermost layer is equipped with a radio frequency identification module. When working, the radio frequency identification module obtains surrounding environment information, and Use the acquired information to effectively locate the robot. At the same time, the radio frequency identification module transmits the identification information to the voice module, and the operator is notified of the identification information through the voice module. The radio frequency identification module plans the optimal or sub-optimal path according to the target point information obtained by the voice module collected by the voice combined with the environmental map. When the robot is ...

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 guide device, in particular to a radio frequency identification multi-sensor voice guide robot and a path planning method suitable for blind people, which are highly practical, have a wide range of application, are reliable and safe. Background technique [0002] Visual impairment is a disease that has a serious impact on the quality of human life. There are approximately 140 million visually impaired people in the world. Of these 45 million people are blind, and a blind person is born every 5 seconds in the world. There are nearly 13 million people with visual impairment in my country, of which 5.5 million are blind, and the number is increasing by 450,000 every year. For most blind people, the main reason that affects their quality of life is their inability to walk freely, and they cannot avoid obstacles in the environment as flexibly as normal people. With the rapid development of robotics, the research and developmen...
