Abstract

The invention provides an indoor mobile robot based on sound source positioning. Power supply realizes voltage conversion through a power supply module, the power supply module supplies power to a chassis motor through a motor drive module, a rotating shaft of the chassis motor is connected with driving wheels, the power supply module further supplies power to an ultrasonic ranging module, an ultrasonic receiving module, a microphone and a singlechip microcomputer separately, ultrasonic signals emitted by the ultrasonic ranging module are returned by obstacles and received by the ultrasonic receiving module, the ultrasonic receiving module sends signals to a singlechip microcomputer, and the singlechip microcomputer realizes obstacle avoidance through calculation through the driving wheels. The indoor mobile robot based on sound source positioning can locate according to the sound and realize three-dimensional coordinate calculation of the sound source position in an indoor environment, control a trolley to automatically close to the sound source position starting from the initial position, and realize the function of autonomous obstacle avoidance in the moving process.

Description

technical field [0001] The invention belongs to the field of robots, in particular to an indoor mobile robot based on sound source localization. Background technique [0002] As an intelligent individual facing complex environmental backgrounds, robots are faced with a world of multi-modal information. For various application environments, they have corresponding information processing systems and information acquisition methods, and can make corresponding decisions according to changes in the environment. Equipping robots with various external sensors to enable them to have higher performance indicators and wider application ranges is an important means for robots to develop intelligently. [0003] Robot vision technology has greatly broadened the application range of robots and improved the working efficiency of robots. However, visual perception is limited by line of sight and visibility, and visual perception will fail when the light conditions are poor or obstructed by...
