Localization of networked mobile sensors and actuators is an active research field. One traditional approach in order to localize a mobile node has been the use of laser sensors. In some special circumstances, like a smoky environment, the use of this type of optical sensor is not a good solution. The use of radio and ultrasound signals can be used as a feasible alternative to node localization. Within the context of the EU GUARDIANS Project (Group of Unmanned Assistant Robots Deployed In Aggregative Navigation supported by Scent detection) one essential aspect is having a simple localization method of a firefighter followed by a squad of robots, that allows tracking their instant position in the space related to the base station. The authors of this paper have been developing hardware devices capable of obtaining relative positions among them and the firefighter, and have studied several networking protocols that can be useful in those situations, using wireless links provided by Wi-Fi cards of the mobile nodes, as well as the sonar sensors and radio synchronization signals.

This paper describes a real-world demonstration that involves two kinds of human-robot interaction: (1) In-situ interaction between a team of robots and a firefighter, and (2) the interaction between a remote operator and the whole system from a base station. The team of robots can provide the firefighter with environmental information to support and enhance its operation in situations where smoke can be present. First of all, the paper describes the overall system, focusing on the devices that are used, and the hardware/software architecture. Then, the paper explains the in-situ human-system interaction which is the way the firefighter interacts with the robot team, by obtaining the information directly to its helmet and by setting up a firefighter following behaviour using both laser and sonar/radio techniques. After that, the paper describes the way the whole system can be monitored and controlled remotely via a base station.

A practical solution based on multi-agent protocols for the development of real-world multi-robot applications is presented. FIPA standard protocols implemented by the JADE library provide the standard functionality for a number of tasks. Robot behaviors are built upon the player middleware. Such components provide off-the-shelf tools which allow a straightforward implementation of indoor localization and navigation tasks for a team of mobile robots. Such integration combines proven mobile robot algorithms with a distributed infrastructure, and extends the capabilities from a robot alone to a whole team of robots, thus allowing the development of cooperative applications. As a proof of concept, an auction-like goal assignment task is presented: the robot team is given a goal, and each robot proposes an estimated cost for achieving it, then the best proposal is selected. Most of the control flow is automated by the standard interaction protocols. Experimental evaluation demonstrates the advantages of combining both frameworks, for a practical yet sound development of multi-robot applications.
