Abstract

The invention discloses a mobile robot autonomous cruise method for reliable WIFI connection. The method comprises the following steps that 1, a robot traverses the whole environment through autonomous exploration navigation, and a WIFI two-dimensional distribution probabilistic model is built according to WIFI signal intensity data of limited measuring points at the access position by means of a Gaussian process regression model; 2, environmental grid maps are built at the same time and mixed with WIFI signal intensity distribution to generate a mixed map, namely a WIFI map; 3, the built WIFI map is utilized for carrying out obstacle avoidance navigation, and therefore it is ensured that the path through which a robot passes bypasses the WIFI signal weak area while the optimal path obstacle avoidance navigation is achieved. The WIFI signal distribution of the whole indoor room can be estimated only based on the data of the limited WIFI signal intensity measuring points through a machine learning algorithm, and the method is applicable to application occasions with high requirements for real-time wireless network connection in remote mobile robot cruise monitoring.

Description

technical field [0001] The invention relates to a reliable WIFI connection-oriented mobile robot autonomous cruising method, which belongs to mobile robot navigation and remote monitoring. Background technique [0002] The wireless network gets rid of the shackles of the wire, and the data collection and monitoring are carried out through the wireless communication network. Good confidentiality and other advantages. This also makes the advantages of intelligent mobile robots controlled by wireless communication methods more and more obvious. In the remote monitoring application of mobile robots using indoor WIFI wireless network, the navigation mode of mobile robots mainly has two working modes: [0003] One way of working is the remote teleoperated navigation mode. Most patrol monitoring robots work in the teleoperation mode. The monitoring personnel manipulate the robot movement through the remote client software interface. , Zhou Qingrui, Research and Implementation o...
