In this paper, we consider a distributed system that consists of a group of teams of worker robots that rely on physical robot messengers for the communication between the teams. ...
We describe approaches for satisfying the real-time collision detection requirements of distributed virtual environments. We assume a distributed virtual environment is deployed u...
