A simple and robust network protocol for remote controlled robot under punctuated network environment

Software architecture with RESTful API is proposed for ILI robot system under unstable networking environment in order to increase reliability, scalability, independency, and generality, yet simple to implement. Evaluation of the architecture showed that the system could be flexibly adapted to emergency cases, which is performed for diverse scenarios including sudden shutdown of component, hot-swap of component, network failure, etc. Consequently, the proposed software architecture is conducted to reduce complexity of implementation and maintenance, to increase scalability, and to allow easy rescue and recovery scheme.
