Abstract

The invention provides an indoor robot navigation system and method. The system comprises a man-machine interaction device, a data collection device and a data analysis device; the man-machine interaction device receives terminal-point position coordinate and terminal-point position attitude information input by a user; the data collection device obtains preset position coordinate and present position attitude information, updates a local area map in real time, and obtains a corresponding second coordinate of a dynamic barrier in a 2D global static map via coordinate transformation; and the data analysis device generates a global reference path via a first algorithm, and plans an optimal speed vector of a robot in next time by utilizing a second algorithm to obtain the optimal speed vector, and thus, the robot moves according to the optimal speed vector. The indoor robot navigation system and method are higher in practicality.

Description

technical field [0001] The invention relates to a robot navigation system and method in the field of artificial intelligence and automation, in particular to an indoor robot navigation system and method. Background technique [0002] Navigation technology is a method of guiding a certain device to move from the current starting point to the ending point of the specified route. Navigation technology has broad application prospects in transportation, home services, military fields, etc., and it is also one of the hot research technologies at present. In terms of transportation, navigation technology can be used to realize the autonomous driving of unmanned vehicles and avoid obstacles, and can also complete intelligent logistics scheduling in large warehouses; in terms of home services, it can help small robots like sweeping robots complete Indoor fixed-point movement; in the military field, navigation technology can be used in fixed-point strikes of missiles, fixed-point pat...
