METHOD AND SYSTEM FOR AUTOMATICALLY CHARGING ROBOT BASED ON ULTRASONIC WAVE
First Claim
1. A method for automatically charging a robot based on ultrasonic wave, comprising the following steps:
- detecting, by the robot, a battery level, and enabling a charging mount to send an ultrasonic pulse signal via wireless communication if the battery level is less than a predetermined threshold;
receiving, by the robot, an ultrasonic pulse signal sent by an ultrasonic transmitting module by using a first ultrasonic receiving module and a second ultrasonic receiving module that are configured on the robot;
calculating, by the robot, a distance and deflection of the robot relative to the charging mount according to the ultrasonic pulse signals respectively received by the first ultrasonic receiving module and the second ultrasonic receiving module;
approaching, by the robot, the charging mount according to the distance and deflection; and
interconnecting, by the robot, with the charging mount for charging when the robot moves to the front of the charging mount or the distance and deflection are less than predetermined thresholds.

Abstract
In a method and system for automatically charging a robot based on ultrasonic wave according to the present disclosure, by configuring an ultrasonic transmitting module and a wireless communication module on a charging mount, and configuring two ultrasonic receiving modules and a wireless communication module on the robot, the robot calculates a distance and deflection of the robot relative to the charging mount according to signal strengths of received ultrasonic signals and a strength difference therebetween, and completes automatic tracing of the robot in combination with a motion control system and a posture adjustment strategy to automatically charge the robot. The method and system according to the present disclosure have a low cost, are suitable for a complicated application environment, and improve intelligence of the robots.
