Multiple Mobile Robot Systems [chapter]

Lynne E. Parker
2008 Springer Handbook of Robotics  
However, explicit communication is limited in terms of fault tolerance and reliability, because it typically depends upon a noisy, limited-bandwidth communications channel that may not continually connect  ...  In the area of robustness, multi-robot teams still need improvements in the ability to degrade gracefully, reason for fault tolerance, and to achieve complexity without escalating failure rates.  ...

Hoplites: A Market-Based Framework for Planned Tight Coordination in Multirobot Teams

N. Kalra, D. Ferguson, A. Stentz
Proceedings of the 2005 IEEE International Conference on Robotics and Automation  
In this paper we address tasks for multirobot teams that require solving a distributed multi-agent planning problem in which the actions of robots are tightly coupled.  ...  Robots use the market to efficiently vet candidate solutions and to choose the coordination mechanism that best matches the current demands of the task.  ...  Thus, MVERT facilitates planned coordination for very small time-steps. Like most behavior-based approaches, MVERT is fast, fault tolerant, and can operate under uncertainty.  ...

Multiple Mobile Robot Systems [chapter]

Lynne E. Parker, Daniela Rus, Gaurav S. Sukhatme
2016 Springer Handbook of Robotics  
This is seen in the Internet where multiple gateways, routers, and computers provide for a fault-tolerant system (although the Internet is not robust in other ways).  ...  Modular robots are typically touted for their adaptability, their fault-tolerance, and the relative simplicity of the unit modules.  ...
