A tracking robot positioning system based on ultrasonic and bluetooth

Abstract

The invention provides a tracking robot positioning system based on ultrasonic waves and Bluetooth. The Bluetooth module of the system communicates with the Bluetooth module of the handheld device. The positioning module locates the position of the handheld device according to the data of the analysis module; the local grid map module analyzes the location of the handheld device according to the detection module. The information scanned by the ultrasonic radar constructs a local grid map; the following area planning module plans a travelable area according to the position of the handheld device and the local grid map, and the following module drives the walking device according to the travelable area planned by the following area planning module . The present invention uses the communication between the bluetooth modules, and analyzes the communication data between the bluetooth modules, combined with the information in front of the robot scanned by the ultrasonic radar, constructs a local grid map to realize the purpose of the robot to follow; the present invention guarantees the The robot can safely and reliably realize autonomous following in a complex environment, and at the same time can reduce the economic cost of following the robot.

Description

technical field [0001] The present invention relates to the robot positioning method, in particular to the technical field of a tracking robot positioning system based on ultrasound and bluetooth. Background technique [0002] Following the robot is a hot issue in the research of human-computer interaction. It has a wide range of applications in the robot neighborhood, such as the club bag following the robot on the vast golf course, the following shopping cart in the shopping mall, and the luggage at the airport. The weight follows the robot and so on. The following process is often carried out in a more complex environment, so it is necessary to locate the target to be followed and avoid obstacles to realize the function of following the specified target. [0003] The existing positioning method following the robot mainly uses the vision system on the robot body in the installation to collect the information of the target and the surrounding environment, and then uses the...

Problems solved by technology

[0003] The existing positioning method following the robot mainly uses the vision system on the robot body in the installation to collect the information of the target and the surrounding environment, and then uses the algorithm of image processing to locate the target. This method is easily affected by the environment. Similar objects interfere, and there will be static and dynamic obstacles in the process of following the robot. The robot must have an obstacle avoidance function, but the current obstacle avoidance algorithm has a high complexity and has the defect that it is easy to enter a local optimum

At the same time, the cost of following the robot using the vision system is high and cannot adapt to the economic capabilities of most people.
