Abstract:

A low cost goods guided vehicle based on embedded electronic System is designed in this paper.Use indoor self-positioning sensors,differential drivers and multimedia interaction modules to automatically transfer goods to designated locations.Among them the core indoor self-localization function is achieved by fusing dead-reckoning and visual measurement involving inertial measurement unit (IMU),a pair of hall encoders and a camera.On this basis, audio files related with the location coordinates are embedded into the module of multimedia interaction.Then the robot can approach the goods location and wait for the goods to load,and finally automatically transfer goods to designated locations.A prototype of the goods guided vehicle is developed to prove the rationality of the design with an example introduction.
