Abstract

The invention provides a navigation method and a corresponding robot thereof. According to the navigation method and the corresponding robot thereof, when a user needs to navigate to a destination, anavigation task is input to the robot, the robot can obtain the navigation task, and the navigation task includes the destination; and then a navigation topological graph between a navigation startingposition and the destination is determined according to an environment map, the shortest path search is conducted on the navigation topological graph to obtain the shortest topological path between the navigation starting position and the destination, and the shortest topological path between the navigation starting position and destination is planned. In order to improve the search efficiency and real-time in the navigation process, the robot generates a collision-free navigation strategy of the robot according to obtained road environment information, motion parameter information of the robot and the shortest topological path so that the robot can be controlled to complete the navigation task set by the user without collision according to the collision-free navigation strategy.

Description

technical field [0001] The present application relates to the field of computers, in particular to a navigation method and a corresponding robot. Background technique [0002] With the development and application of intelligent mobile robot technology, how to move quickly and autonomously without collision has become a core issue, among which path planning is the most important. At present, the commonly used global path planning algorithms include traditional methods, intelligent bionic algorithms, and heuristic search methods. However, when the mobile robot moves in a large-scale and highly dynamic environment, the traditional path planning algorithm not only needs to have a certain prior knowledge of the environment map, but also requires a large storage space to store relevant environmental information. As the complexity of the road environment increases and the calculation distance increases, the efficiency of a single path planning algorithm will drop significantly, es...
