Applying Dynamic Software Architecture Management to Home Service Robot Software

Home service robots increasingly need to provide diverse and complex services such as cooking, sweeping and dishwashing. These services inevitably require a number of software functions simultaneously. For example, the cooking service requires an arm manipulation function to grasp dishes, an navigation function to move around, an object recognition function to find foods, an speech recognition function to understand user requirements, and etc. However, when the services and software functions are executed simultaneously in a robot without run-time software management, those may cause malfunction due to resource contention. In this paper, we describe the situation that causes resource contention and formulate architecture-based adaptation in robot software systems. Based on the formulation we proposed an approach to dynamic robot software management that effectively uses robot computing resources.
