System and method for controlling robot

Abstract

The invention discloses a system and a method for controlling a robot, relates to the field of robots, and solves a technical problem that a robot is easily deviated when working on a slope in the prior art. The system for controlling the robot comprises a master control module, a running mechanism and a direction collection module, wherein the direction collection module is connected with the master control module and used for collecting direction information of the robot. The direction collection module comprises a magnetic field induction sensor for collecting earth magnetic field data, and a gravitational acceleration sensor for collecting gravitational acceleration data. The master control module obtains the direction information of the robot through the earth magnetic field data of the magnetic field induction sensor and the gravitational acceleration data of the gravitational acceleration sensor, and controls the robot for stably moving in a line through the running mechanism. The invention can be applied to movement control of robots.

Description

【Technical field】 [0001] The present invention relates to the field of robotics. 【Background technique】 [0002] The lawn is an important part of urban greening. Through the mowing robot, the mowing efficiency is improved to a certain extent, the labor intensity is reduced, and a large amount of labor resources are saved. Depending on the situation, there are usually spiral motion path control, contour tracking motion path control, random random path control, and parallel reciprocating motion path control. The mowing robot reciprocates along multiple parallel straight lines. Reciprocating motion path control is the most ideal and efficient motion control method for robots. The intelligent lawn mower in the prior art determines the direction by sensing the geomagnetic field to ensure that the robot always moves in a fixed direction when moving in a straight line. However, this method only achieves better results when the ground is relatively flat. In the case of large or un...

Problems solved by technology

The intelligent lawn mower in the prior art determines the direction by sensing the geomagnetic field to ensure that the robot always moves in a fixed direction when moving in a straight line. However, this method only achieves better results when the ground is relatively flat. In the case of large or uneven conditions, the body of the robot is tilted, and the magnetic field coordinates collected by the robot are also tilted. Therefore, the collected magnetic field data is different from the actual geomagnetic field, and there is an error in the movement direction calculated according to the collected magnetic field data, resulting in Misjudgment of the direction, causing deviation and affecting the effect of mowing
