Follow robot positioning system based on ultrasonic waves and Bluetooth

Abstract

The invention provides a follow robot positioning system based on ultrasonic waves and Bluetooth. A Bluetooth module of the system is in communicated with a Bluetooth module of a handheld device. The position of the handheld device is positioned through a positioning module according to data of an analysis module. A local grid map module establishes a local grid map according to information which is analyzed through a detection module and scanned through ultrasonic radar. A follow area planning module plans an area where a robot can advance according to the position of the handheld device and the local gird map. A follow module drives a walking device according to the area which is planned through the follow area planning module and allows the robot to advance. The local grid map is established through the communication between the Bluetooth modules and by analyzing communication data between the Bluetooth modules and comprehensively utilizing information, scanned by the ultrasonic radar, in front of the robot, and the following aim of the robot is achieved; it is ensured that autonomous following of the robot can be safely and reliably achieved in a complex environment, and meanwhile the robot following economic cost can be reduced.

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.
