Embodiment Construction

[0033] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0034] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

[0035] On the mobile robot chassis, in order to detect obstacles in the surrounding environment, a certain number of distance sensors are usually installed, such as: infrared distance sensors and ultrasonic distance sensors. By accurately measuring the distance between...

Abstract

The invention belongs to the technical field of robots, and provides an obstacle detecting method and device for a mobile robot, terminal equipment and a computer storage medium. The device comprisesa plurality of emitting probes for emitting distance measuring signals, a plurality of receiving probes for receiving the distance measuring signals reflected by an obstacle and a control circuit forconnecting the emitting probes with the receiving probes; and the control circuit is used for controlling at least two receiving probes to receive the distance measuring signals while one or more emitting probes are controlled to emit the distance measuring signals, calculating the position of the obstacle according to a time difference between emitting the distance measuring signals and receivingthe distance measuring signals, and estimating the size and the appearance of the obstacle. According to the obstacle detecting method and device for the mobile robot, the terminal equipment and thecomputer storage medium, the separated multiple emitting probes and the multiple receiving probes are integrally controlled, the measuring precision of the mobile robot towards the obstacle is improved, and the obstacle measuring dead zone is reduced.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to an obstacle detection method, device and computer storage medium for a mobile robot. Background technique [0002] A robot is a machine device that performs work automatically. During the work process, it is necessary to accurately obtain information about obstacles within the field of vision for corresponding navigation and obstacle avoidance in order to reach the set destination. [0003] In the prior art, a plurality of distance sensors are arranged on the chassis of the robot, and the distance sensors are triggered to measure the distance of obstacles in a round-robin manner. For example, first trigger one of the distance sensors to measure the distance of obstacles, and after a set time, trigger the other distance sensor to measure the distance of obstacles. This ranging method reduces the ranging sampling frequency of obstacles, causing the robot to respond slow...
