Autonomous charging system and charging method thereof for intelligent home accompanying robot

Abstract

The invention discloses an autonomous charging system and a charging method thereof for an intelligent home accompanying robot. An infrared emission module emits infrared pulse signals of different frequencies and the signals are transmitted to an infrared receiving module; a robot main controller controls movement of the robot, and charging butt joint between a charging station and the robot is realized during the moving process of the robot; a butt joint detection module is used for detecting whether the charging butt joint between the charging station and the robot is completed and transmitting the corresponding signals to the robot main controller after the butt joint is completed, and the main controller controls the robot to move and charging begins; and a charging completion detection module is used for transmitting the corresponding signals to the main controller after charging of the robot is completed, and the main controller controls the robot to automatically drive away from the charging station. The butt joint success rate and the efficiency are high, and 100% butt joint in limited space can be achieved; and as infrared and ultrasonic sensors are used, the use is simple, and the device cost is low.

Description

technical field [0001] The invention relates to the technical field of autonomous charging of robots, in particular to an autonomous charging system and a charging method for a family intelligent escort mobile robot. Background technique [0002] The mobile service robot has many tasks, strong functions, and needs to walk autonomously. It generally consumes a lot of power, requires frequent charging, and requires high reliability and efficiency in the charging process. The charging device has a low cost. [0003] Restricted by the current level of battery technology, poor battery life is a common problem for mobile service robots. The robot consumes a lot of energy during continuous operation and needs to be recharged frequently. If the manual charging method is adopted, it will not only increase the burden on people, but also reduce the autonomy and intelligence level of the robot to perform tasks. Therefore, it is very necessary for the robot to quickly find the charging ...

AI Technical Summary

Problems solved by technology

Visual positioning is immature, difficult and has a low success rate; laser navigation is more mature than visual positioning, but its cost is higher; infrared guidance and ultrasonic detection are low in cost, but the navigation effect is poor when used alone, and it is easy to enter the dead zone. area, unable to complete the self-charging task
