초록

네트워크 기반 로봇에서 로봇은 한정된 자원을 가지며 서비스에 따라 필요로 하는 입출력 장치와 컴퓨팅 능력 및 응답 실시간성이 다르다. 본 논문에서는 네트워크 기반 로봇에서 로봇이 다양한 서비스를 효율적으로 수행하고 서비스의 실시간성을 제공하도록 하기 위하여 서비스 실 행 컨텍스트를 동적으로 관리하는 방법을 제안한다. 실제 네트워크 기반 로봇에 적용하여 실험한 결과, 제안한 방법은 서비스 실행의 실시간 응답성을 만족하며 로봇의 자원 사용률을 향상시켰다. 제안한 방법은 서비스 실행 컨텍스트에 대한 변경이 용이하므로 센서 및 새로운 서비스 에 대한 확장성과 융통성을 제공하며 로봇 서비스의 재사용성을 증대시킨다.

Robots have limited computing resources and robot services have different requirement such as sensors, actuators, computational capabilities and timeliness. In this paper, we propose a dynamic management method of service execution contexts to perform various services efficiently and to meet the time constraint of service in network-based robots. The proposed method is tested in the real network-based robot system. The results show that the real-time requirement for services is satisfied and the resource utilization is improved. The proposed method provides the extendability and flexibility of sensors and services by aptly modifying service execution contexts and increases the reusability of service.
