Abstract

The invention discloses a mobile robot platform self-positioning system and a self-positioning method. The self-positioning system comprises a mobile robot platform and a positioning device, wherein the positioning device is formed by three beacons arranged on the ceiling. Each beacon is provided with a Bluetooth module, and a Bluetooth module is also inlaid in a mobile robot platform and communicates with the beacon, so as to measure an oblique angle distance between the mobile robot platform and the beacon currently. Vertical distance from the ceiling to the floor is measured by a height measuring unit of one beacon. Accordingly, the positioning device calculates horizontal distance between the positioning device and the mobile robot platform according to the measured oblique angle distance and the vertical distance, and obtains the relative position of the mobile robot platform relative to the positioning device by using a trilateral positioning algorithm.

Description

technical field [0001] The invention relates to a self-positioning system and a self-positioning method of a mobile robot platform. Background technique [0002] Smart devices such as mobile robot platforms, such as sweeping robots, have become increasingly popular in recent years. Most of the mobile robots on the market use the built-in infrared sensor or ultrasonic sensor of the mobile robot platform to judge the surrounding environment. If there are obstacles around, they will choose other paths. This method is difficult to collect the position information of the current mobile robot platform. In order to be able to accurately control the movement of the platform, the mobile robot platform must have a specific self-positioning system. [0003] The mobile robot platform can use the environment map model matching positioning, which is also the self-localization method adopted by many mobile robot platforms. The robot detects the surrounding environment through its own va...
