Mobile robot autonomous navigation system and method

Abstract

The invention discloses a mobile robot autonomous navigation system and method. The mobile robot autonomous navigation system comprises an infrared sensor distance measurement unit, an upper computer, a main controller and a motor, and is characterized in that the infrared sensor distance measurement unit is used for measuring the distance between an obstacle in one or more directions and a mobile robot in real time; the upper computer is used for performing path planning on the mobile robot according to the distance between the obstacle and the mobile robot, generating navigation information and sending the navigation information to the main controller; the main controller is used for controlling the motor to operate according to the navigation information sent by the upper computer so as to enable the motor to drive the mobile robot to perform autonomous walking. By using the mobile robot autonomous navigation system and method, requirements for hardware equipment and working environment of the robot are effectively reduced under the condition of ensuring certain navigation accuracy, and the cost-to-performance ratio of products is improved.

Description

technical field [0001] The invention relates to the field of robot control, in particular to an autonomous navigation system and method for a mobile robot. Background technique [0002] Mobile robot is a comprehensive system integrating environment perception, dynamic decision-making and planning, behavior control and execution. It concentrates the research results of sensor technology, computer technology, mechanical engineering, electronic engineering, automation control engineering and artificial intelligence, and is one of the most active fields of science and technology development. In the research on related technologies of autonomous mobile robots, navigation technology is the core of its research, and it is also the key technology for mobile robots to realize intelligence and complete autonomy. Navigation refers to the mobile robot perceives environmental information and its own state through sensors, and realizes the goal-oriented autonomous movement in an obstacle...

Problems solved by technology

[0004] Existing indoor navigation and positioning of robots usually rely on some tags, such as RFID (Radio Frequency Identification, radio frequency identification) or specific icons, which have relatively strong environmental requirements, and need to modify the existing environment, which is not suitable for ordinary family scenes; Robots that rely on vision. These robots have high requirements on hardware and need to run complex vision algorithms in real time. Embedded platforms are difficult to support. At the same time, because of the limitations of ambient light, the advantages in terms of effect and cost are not obvious; there are also lidar-based +UWB robot, this kind of robot has high positioning accuracy and wide working range, but it needs to install at least three base stations, and still needs to modify the surrounding environment, and the cost of lidar is also very high, and it is not very suitable for ordinary family scenes.
