Abstract
Provided are a marker for space recognition, a method of moving and lining up a robot based on space recognition, and a robot, and the robot that lines up and moves based on space recognition includes: a camera sensor that images a marker disposed on a traveling floor of the robot or a side of the traveling floor; and a control unit that analyzes an image captured by the camera sensor, calculates a moving direction or a moving speed of the robot on the basis of the marker, and controls a movement unit.
Claims17
A robot that lines up and moves based on space recognition, the robot comprising:
- a movement unit that allows the robot to move;
- an obstacle sensor that senses an obstacle near the robot;
- a camera sensor that images a marker disposed on a traveling floor of the robot or a side of the traveling floor;
- a force sensor that senses change of a force which is applied to a handle assembly of the robot;
- and
- a control unit that analyzes an image captured by the camera sensor, calculates a moving direction or a moving speed of the robot based on the marker, and controls the movement unit,
- wherein, when the force sensor senses the change of the force while the control unit moves the robot based on the marker, the control unit moves the robot based on the change of the force sensed by the force sensor and then moves the robot in parallel to the marker depending on whether the marker and the moving direction of the robot match each other.
A method of moving and lining up based on space recognition, the method comprising:
- causing a movement unit of a robot to move the robot;
- causing a camera sensor to image a marker which is disposed on a traveling floor of the robot or a side of the traveling floor while moving;
- analyzing an image captured by the camera sensor and identifying the marker;
- causing a control unit of the robot to calculate a moving direction or a moving speed of the robot based on the marker;
- and
- causing the control unit to control the movement unit using one or more of the calculated moving direction and the calculated moving speed,
- wherein the marker includes one or more light sources that emit light,
- wherein the method further comprises causing the control unit to calculate the moving speed or the moving direction in a space in which the marker is disposed using one of a color, a shape, and a flickering pattern of the marker,
- wherein the marker is a line marker, and
- wherein the method further comprises causing the control unit to increase or decrease the moving speed in proportion to or in inverse proportion to the width of the line marker.
A method of moving and lining up based on space recognition, the method comprising:
- causing a movement unit of a robot to move the robot;
- causing a camera sensor to image a marker which is disposed on a traveling floor of the robot or a side of the traveling floor while moving;
- analyzing an image captured by the camera sensor and identifying the marker;
- causing a control unit of the robot to calculate a moving direction or a moving speed of the robot based on the marker;
- causing the control unit to control the movement unit using one or more of the calculated moving direction and the calculated moving speed;
- causing the force sensor to sense change of a force while the control unit moves the robot based on the marker;
- causing the control unit to move the robot based on the change of a force sensed by the force sensor;
- and
- causing the control unit to move the robot in parallel to the marker depending on whether the marker and the moving direction of the robot match each other.
