Embodiment 1

[0030] A robot for autonomous navigation, including a motion module, a control module, a gyroscope, and a laser sensor. The motion module includes four universal wheels, two direction wheels and a motor, and the direction wheels are connected to the output shaft of the motor. The control module includes a data storage unit, a data processing unit, an information receiving unit, and a signal output unit, the motor is connected to the signal output unit, and the gyroscope and laser sensor are connected to the information receiving unit.

[0031] The gyroscope and laser sensor collect information such as the speed, angle, and direction of the robot during its advancement, and transmit the relevant information to the information receiving unit. The information receiving unit transmits the relevant information to the data processing unit, and the data processing unit processes the relevant data. On the one hand, the data processing results are transmitted to the data storage unit, a...

Embodiment 2

[0043] Different from Embodiment 1, the autonomous navigation robot further includes a communication module connected to the signal output unit.

[0044] When the target position is not in the same room as the robot's current position, the robot needs to pass through the door to reach the target point, and the door is closed when the robot is moving forward.

[0045] When the robot travels to the position of the door, because the door is closed, the robot assumes that the door is an obstacle, so it goes around. After a certain distance in the direction of the circle, the gyroscope perceives that the direction of the robot’s progress is inconsistent with the direction of the target path (that is, the direction of progress is different from that of the target path). The angle between the front ends of the target path exceeds 30°), at this time the robot turns and adjusts its forward direction.

[0046] After two attempts, the robot autonomously determines that the door is a nece...

Abstract

The invention discloses an autonomous navigation robot which comprises a motion module, a control module, a gyroscope and a laser sensor, wherein the motion module comprises four universal wheels, two steering wheels and a motor; the steering wheels are connected with an output shaft of the motor; the control module comprises a data storage unit, a data processing unit, an information receiving unit and a signal output unit; the motor is connected with the signal output unit; and the gyroscope and the laser sensor are connected with the information receiving unit. The invention further discloses an autonomous navigation method of the robot. The method comprises the following steps: pre-storing a map, performing route planning, avoiding an obstacle and the like. According to the autonomous navigation robot and the method disclosed by the invention, the types of obstacles can be identified, and the obstacles can be autonomously avoided; and the time or distance priority rule can be set according to needs, and real optimization of a target route is realized.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to an autonomous navigation robot and an autonomous navigation method thereof. Background technique [0002] Today, with the development of artificial intelligence and robot technology, there are many smart devices that can move by themselves, such as household sweeping robots, security inspection robots, etc. These smart devices can usually sense the surrounding environment by themselves, generate maps and plan walking route. [0003] Navigation technology is one of the core technologies of mobile robots, which means that mobile robots perceive environmental information and their own state through sensors, and realize target-oriented autonomous movement in an obstacle environment. The main navigation methods of most mobile robots include: magnetic navigation, inertial navigation, visual navigation, etc. [0004] The current navigation has the problems of insufficient i...
