Mobile robot navigation system and mobile robot

Abstract

The invention relates to the technical field of robots, and discloses a mobile robot navigation system and a mobile robot. The mobile robot navigation system comprises a mobile robot and a target board. The mobile robot comprises a body, a walking mechanism, a navigation sensor set, a position sensor set and a control system. The navigation sensor set, the position sensor set and the walking mechanism are all in signal connection with the control system, the navigation sensor set comprises a center laser sensor and a deviation rectifying laser sensor, the deviation rectifying laser sensor is assembled on the body in a swinging mode in the horizontal direction, and a heading target is arranged on the target board. When the deviation rectification laser sensor receives a laser signal reflected by the heading target, the mobile robot deviates from a straight line; whether the mobile robot deviates leftwards or rightwards is determined according to the received position of the deviation rectification laser sensor, so that the walking direction of the walking mechanism is changed by the control system, the walking precision of the mobile robot is improved, special auxiliary equipment and algorithms are omitted, and the use cost of the mobile robot is reduced.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a mobile robot navigation system and a mobile robot. Background technique [0002] Robot automatic driving navigation technology is now dominated by laser radar navigation. The principle of laser radar navigation is based on the horizontal laser radar as the center. The laser beam emitted by the laser radar reaches the bunker (wall or object) and then returns. The distance of the lidar, and then the laser ray is continuously rotated at a fixed speed, and the position of the lidar in the plane space can be constructed through the two parameters of the rotation angle and distance, that is, the map is constructed. Then load the laser radar on the robot chassis composed of controller and motor drive, and use the computer algorithm to realize the purpose of allowing the robot chassis to drive on the planned route in the map. [0003] Although mobile lidar navigation robots have a wide...

Problems solved by technology

[0004] The purpose of the present invention is to provide a mobile robot navigation system to solve the problem that the laser radar navigation robot in the prior art has limited navigation accuracy. When there is a deviation in driving, the relative coordinates of the robot in the map are easy to lose, and the auxiliary equipment and algorithm High cost causes the problem that robot cost increases; The present invention also provides a kind of mobile robot
