Indoor localization in smoke conditions is one of the EU GUARDIANS project goals. When density grows, optical sensors such as laser range finders and cameras cease to be efficient. Zigbee sensor networks provide an interesting approach due fact that radiofrequency signals are propagated easily conditions. Moreover, they permit having alternative communication infrastructure emergency brigades, allowing also implementation algorithms for mobile sensors, actuators, firefighters. The overall...

The increasing demand for underwater robotic intervention systems around the world in several application domains requires more versatile and inexpensive systems. By using a wireless communication system, supervised semi-autonomous robots have freedom of movement and, at same time, allows operator to get camera feedback supervise intervention. Moreover, limited varying bandwidth radio frequency (RF) acoustic modem channels is major obstacle. This paper proposes use progressive (embedded)...

When the results of research in field robotics are presented to scientific community, same question is asked repeatedly: Are really reproducible? Regarding benchmarking issues, some technological areas where complex mechatronic devices, such as robots, have a central role very far from other like physics or chemistry, name but few, reproducibility always mandatory. Aside complexities, comparison between two different algorithms conditions influenced by experimental validation scenario. In...

Nowadays, there is an increasing demand for underwater robotic intervention systems around the world in several application domains. Examples of applications include search and recovery (i.e. aviation or naval accidents), archaeology, offshore industry, environment protection monitoring, etc. The commercially available are expensive far from what it demanded many aspects, justifying need more autonomous, cheap easy-to- use solutions missions. Most them consist remote operated vehicles,...

Mobile robots are nowadays capable of navigating in a semi-structured environment, either alone or formations. Dealing with mobile obstacles, e.g. persons, everyday environments poses additional challenges which being addressed by the research community.

Autonomous manipulation in unestructured underwater scenarios is a high challenging skill that has been poorly studied and becoming more important the last years. One of main problems regarding autonomous manipulation, to find out characteristics object which going be manipulated. This paper presents new approach obtain an accurate 3D reconstruction this object. consists attaching laser stripe emitter camera forearm robotic arm. Moving arm, scans scene where and, at same time, records scan....

When localizing mobile sensors and actuators in indoor environments laser meters, ultrasonic meters or even image processing techniques are usually used. On the other hand, smoky conditions, due to a fire building collapse, once smoke dust density grows, optical methods not efficient anymore. In these scenarios type of must be used, such as sonar, radar radiofrequency signals. Indoor localization low-visibility conditions is one EU GUARDIANS [ 1 ] project goals. The developed method aims...

Benchmarking is nowadays an issue on robotic research platforms, due to the fact that it not easy reproduce previous experiments and knowing in detail which real conditions other algorithms have been performed. Having a web-based tool configure execute benchmarks opens door new opportunities as design of virtual tele-laboratories permit implementation using specific detailed constraints. This fundamental for designing allow be made more scientific manner, taking into account these should...
