Abstract

This study presents the remote control of a board robot using an IMU sensor based on Bluetooth communication. The board robot is a kind of riding robot controlled throng wireless communication by a user. The user wears the proposed IMU sensor controller, and changes a direction of the robot by the angles of IMU sensor. Bluetooth is used for wireless communication between the board robot and its user. The IMU sensor in the remote controller is used for recognition of a number of actions, which are measured as analog signals. The user actions have five commands ('1'right '2'neutrality '3'left '4'operation '5'stop), which are transmitted from the user to the board robot through Bluetooth communication. Experimental results show that proposed IMU interface can effectively control the board robot.

본 논문은 IMU센서를 이용하여 보드로봇을 무선으로 제어하는 연구에 관해 다룬다. 사용된 보드로봇은 일종의 탑승형 로봇으로 탑승자는 옆으로 서서 앞을 보며 제어한다. 탑승자는 제안된 무선제어기를 팔의 상박에 착용하고, 무선제어기의 각도에 따라서 방향전환을 할 수 있다. 무선제어를 위해 블루투스(Bluetooth)가 사용되며, 사용자의 행동에 따른 다섯 종류의 명령('1'우회전, '2'중립, '3'좌회전, '4'운전, '5'정지)을 IMU 센서로 측정하여 기울기에 대한 디지털 값을 보드로봇의 제어기로 전송한다. 보드로봇에서 수신된 값은 정해진 명령을 기반으로 모터를 제어한다. 결과적으로, 제안된 IMU 센서 기반의 사용자 인터페이스는 실제의 보드를 조정하듯이 보드로봇을 쉽고 편리하게 제어할 수 있다.
