Guide robot and its moving area calibration method

Abstract

The invention discloses a navigation robot and a method for calibrating its moving area, wherein, the navigation robot includes a casing, a control module and a light-emitting module arranged on the casing, the light-emitting module is electrically connected to the control module, and the control module has a Receive the signal input end of the motion command, and the control module drives the light emitting module to perform light display in the corresponding area around the casing according to the received motion command. The technical solution of the invention enables the navigating robot to display and demarcate the area to be passed, give an intuitive movement trend reminder, and avoid situations such as collisions between humans and the robot or multiple avoidances.

Description

technical field [0001] The invention relates to the field of navigation robots, in particular to a navigation robot and a method for calibrating its moving area. Background technique [0002] Autonomous navigation robot is a type of intelligent robot that is used in exhibition halls and other places to lead visitors to different functional areas according to business needs, and give corresponding explanations and answer related questions. It passes through the two driving wheels at the bottom And 1 driven wheel, capable of rapid movement. At present, the guide robot relies on its own sensors to locate and avoid obstacles, but in practical applications, it is found that when the guide robot is moving or turning, it will encounter various emergencies, such as: [0003] 1. During the movement of the guide robot, if someone is on its trajectory, it will automatically avoid obstacles based on the feedback information from its own sensors. Because people are unpredictable about t...

Problems solved by technology

[0003] 1. During the movement of the guide robot, if someone is on its trajectory, it will automatically avoid obstacles based on the feedback information from its own sensors. Because people are unpredictable about the direction of robot obstacle avoidance, they will avoid to one side based on instinct, often The avoidance direction of the human is consistent with the obstacle avoidance direction of the guide robot, causing two or more times of avoidance between the guide robot and the human, making the robot need to spend more time or choose a non-optimal path to reach the preset area, and even cause The robot misjudged that there were insurmountable obstacles around, and could not reach the pre-set area and turned around in situ, affecting the normal operation of the robot;

[0004] 2. When the guide robot suddenly moves from a static state, since people do not know in advance that the guide robot will move, let alone which direction the guide robot will move, it is easy for people to suddenly appear in the place where the guide robot is about to arrive. The situation in the area will cause the guide robot to collide with people, causing injury to people or causing damage or malfunction of the guide robot.
