Embodiment Construction

[0030] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. Wherein, similar elements in different implementations adopt associated similar element numbers. In the following implementation manners, many details are described for better understanding of the present application. However, those skilled in the art can readily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the application are not shown or described in the description, this is to avoid the core part of the application being overwhelmed by too many descriptions, and for those skilled in the art, it is necessary to describe these operations in detail Relevant operations are not necessary, and they can fully understand the relevant operations according to the description in the specification and genera...

Abstract

The present invention provides a mobile robot, and a method and a system for obstacle avoidance and path programming thereof. The method plans the shortest path between a position where a robot is located and a target point, obtains distance information and edge information detected in real time, determines the type of the distance information, emits a corresponding control instruction according to the type of the distance information, the edge information and a preset control rule, and regulates the direction angle of the robot to allow the robot to move along the shortest path and to avoid obstacles on the paths in the driving process. The method provided by the invention plans the shortest path between the position where the robot is located and the target point by employing a current A*search algorithm according to the real-time position of the robot and the target point aiming at a condition that obstacles are dynamic and a condition that the positions of the obstacles are moved in the path planning step, and therefore, it is ensured that the robot moves along the shortest path in the process that the robot moves the target point.

Description

technical field [0001] The invention relates to a mobile robot, in particular to a mobile robot and its obstacle avoidance and path planning method and system. Background technique [0002] With the application of mobile robots in the automotive industry, household consumer electronics, shopping mall guidance, and underwater equipment more and more widely, people have been paying attention to the research of mobile robots. Many robots on the market only have simple walking functions (for example, sweepers only have fixed bow walking and recharging functions), but do not have real obstacle avoidance and path planning functions. Although some mobile robots have the function of path planning, they have constraints on the external environment, and often need to place some specified markers at specified positions, which do not have scalability; other mobile robots are aimed at dynamic obstacles or obstacles that have moved their positions. The path at the beginning is still used...
