Robot device and method for locating target

Abstract

A robot device comprises at least accessory equipment. The robot device further comprises a map building unit used for scanning surrounding environment data and building a map according to the surrounding environment data; a target search unit used for identifying the at least accessory equipment and simultaneously detecting distance and angle data of the at least accessory equipment relative to the robot device; and a target location unit used for judging the accurate position of the at least accessory equipment in the map according to the map and the detected distance and angle data. The invention also provides a method for locating a target by the robot device. Through the robot device and its target location method, cooperation between the robot device and the accessory equipment can be more accurate and flexible.

Description

technical field [0001] The invention relates to the field of robots, in particular to a robot device and a method for locating a target. Background technique [0002] In recent years, with the development and progress of science and technology, robot products have emerged one after another, and robot products represented by sweeping robots have entered thousands of households, forming a strong market demand and influence. Because of its certain intelligence, intelligent robots can basically perform related functional actions within a certain range without the user's operation, while the robot will need to perform functional operations with auxiliary equipment indoors, such as charging, picking up objects, etc. This involves localization and recognition of the relative positions of the robot and the attached equipment. [0003] The main technical difficulty in finding the position of the robot and the auxiliary equipment and subsequent functional operations lies in the relat...

Problems solved by technology

In the current technology, there are four main ways for intelligent robots to locate auxiliary equipment: infrared positioning, ultrasonic radar positioning, Bluetooth positioning, and WIFI positioning. TM Signal strength positioning: ①Infrared positioning is highly accurate, but because this kind of light cannot penetrate objects, infrared rays can only be positioned within the line of sight. If something is blocked, the signal will be lost; ②Use ultrasonic positioning to find Ancillary equipment, ultrasonic waves mainly locate objects through reflective ranging, similar to how bats calculate the distance between objects and themselves through triangular positioning. Ultrasonic ranging is greatly affected by external interference and non-line-of-sight propagation, and the manufacturing cost of the circuit is relatively high. High, practicability is not ideal; ③The third is Bluetooth technology. Bluetooth locates by measuring the strength of the model. Its power is relatively low. The positioning system made by Bluetooth is relatively small and easy to integrate in the robot circuit. This technology, its function can only be distance radius radiation, beyond this distance radius signal weakening reminder, can not know the exact orientation and relative distance; ④The last kind of Wifi signal strength positioning is similar to Bluetooth, and its cost is more Expensive, not cost-effective
