Mobile robot and obstacle detection method

Abstract

The invention discloses a mobile robot which comprises a robot body, a moving part, distance measuring sensor units and a control unit. The robot body is supported by the moving part, the distance measuring sensor units are arranged on the surface of the robot body, and the control unit is arranged in the robot body. The distance measuring sensor units are in communication connection with the control unit, the four sets of distance measuring sensor units are located at the front end, the rear end, the left side face, the right side face and the lower bottom face of the robot body correspondingly. The control unit is used for receiving the distance information of the distance measuring sensor units and determining the information of obstacles around the robot according to the distance information. The invention further discloses an obstacle detection method based on the mobile robot. According to the invention, the omnibearing obstacle detection in the walking process of the mobile robot can be realized in a low-cost manner, the mobile robot and the method are suitable for an uncertain scene and a dynamic change scene, and the emergency detection efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of emergency rescue, in particular to a mobile robot and an obstacle detection method. Background technique [0002] Emergency rescue generally refers to activities and plans to prevent, prepare, respond and recover to sudden and destructive emergencies. According to different types of emergencies, emergency rescue is divided into health emergency, traffic emergency, fire emergency, earthquake emergency, factory and mine emergency, family emergency and other fields. In some emergency accidents such as earthquakes, large-scale building fires, explosions and collapses of factories and mines, the site's terrain is complicated and the environment is dangerous. If rescuers enter rashly, it is easy to cause unnecessary casualties. For this reason, a solution for on-site detection using detection equipment such as mobile robots has been proposed. [0003] In order to realize autonomous walking of mobile robots, one solu...

Problems solved by technology

[0003] In order to realize the autonomous walking of the mobile robot, one solution is to install a radar on the main body of the robot to perform sectoral or omni-directional scanning to obtain the information of surrounding obstacles. However, in an uncertain scene, the scene environment changes dynamically at all times, and this solution is difficult to implement. All-round detection, radar is also easy to damage and the cost is high; another solution is to use sensors to detect obstacle information, but the existing sensor obstacle avoidance solutions only consider movement on flat ground, which is difficult in complex scenarios of emergency rescue. effective application
