Continuous Query Processing Over Data, Streams and Services: Application to Robotics

Developing applications involving mobile robots is a difficult task which requires technical skills spanning different areas of expertise, mainly computer science, robotics and electronics. In this paper, we propose a SQL-like declarative approach based on data management techniques. The basic idea is to see a multi-robot environment as a set of data, streams and services which can be described at a high level of abstraction. A continuous query processing engine is used in order to optimize data acquisition and data consumption. We propose different scenarios to classify the difficulty of such an integration and a principled approach to deal with the development of multi-robot applications. We provide our first results using a SQL-like language showing that such applications can be devised easily with a few continuous queries.
