Abstract

In this paper, a new robot system is designed and manufactured to improve the educational robot. The main processor is realized using the ARM Cortex-M3 and the co-processor is implemented by AVR ATMega2560 to deal with data coming from sensor modules. The processor of sensor modules was developed by the AVR ATMega8. The communication system is composed with IIC communication to alleviate the load of main processor. We have developed the educational robot system adopting the hub module for extension characteristics.

본 논문에서는 기존의 교육용 로봇을 개선한 새로운 로봇 시스템을 설계하고 제작하였다. 구현 방법으로는 제어 모듈의 메인프로세서로 ARM Cortex-M3와 보조프로세서로 각 센서모듈에서 들어오는 데이터를 처리하기 위해 AVR ATMega2560을 이용하여 제작하였다. 개발된 센서 모듈의 프로세서는 AVR ATMega8을 사용하였다. 메인컨트롤러가 처리해야 하는 부하를 덜어주기 위해 각 프로세서들과의 통신은 IIC 통신을 사용하였다. 또한 확장성을 보장하기 위해 허브 모듈을 채택한 교육용 로봇 시스템을 개발하였다.
