Development and Experimentation of Mini 4WD AI Control Method Using Geomagnetic Sensor and Magnet

Abstract

This paper describes an approach to position estimation using a geomagnetic sensor to control of mini 4WD AI automatically. In our previous work, position estimation was performed using an external camera, but the error between the estimated and actual positions due to communication delays was significant. We attempt to solve the problem of the communication delay by eliminating external communication using the geomagnetic sensor mounted on the mini 4WD AI. Using the magnetism-sensing characteristics of the geomagnetic sensor, we examined the feasibility of position estimation by placing a magnet on the course.
