Chinas Robot Location Technology

Abstract: Positioning is the process of determining the location of a robot in its work environment. In this paper, according to the different positioning methods and sensors, the positioning technology is divided into four categories, namely, track prediction, signal positioning, map-based positioning, based on visual positioning, and gives the positioning of various types of technology and its main idea Key Technologies. And the positioning method based on visual positioning and track deduction is analyzed in detail. Has a high value of participation.

Robots in the process of movement will encounter and solve the following three questions [1]:

(1) i (robots) now where?

(2) Where am I going?

(3) how do i get there?

The first problem is the overall positioning of its navigation system and its tracking problem, the second and the third is the navigation system path planning problem. The task of mobile robot positioning technology is to solve the first problem above.

Mobile robot commonly used positioning technology

Based on the track prediction of the positioning technology track calculation [4] (Dead Reckoning referred to as DR) is one of the most widely used means of positioning. No external sensor information is required to estimate the position and direction of the vehicle and provide high short-term positioning accuracy. The key to the path estimation technique is to be able to measure the distance traveled by the mobile robot's unit time interval and the change in the robot's course during this time. According to the different sensors, there are mainly based on the inertial sensor path estimation method and the trajectory based on the track calculation and positioning method. The rotation rate and the acceleration rate are measured by the gyro and the accelerometer. The distance of the moving robot and the change of the heading are solved by integrating the measurement result. Then, according to the basic algorithm of the track calculation, the position of the mobile robot is obtained. Attitude, which is based on the inertial device path estimation method.

This method has its own advantages, that is, no external reference. However, with the time drift, after the points, any small constant error will be infinite growth. Therefore, the inertial sensor is not suitable for long-term precise positioning. Trajectory Estimation Positioning techniques are often used to estimate position and attitude. It also has a common feature of track prediction, that is, a self-contained positioning method, the method is simple, low cost and easy to complete in real time.
