VIEW-FINDER

Trials of indoor / outdoor robots at the Royal Military Academy, Belgium: on the foreground the Robudem outdoor robot of partner RMA can be seen and in the background (far-end) the ATRV-Jr iRobot indoor platform (close-ups in next pictures) of partner PIAP can also be seen entering a hangar.

Indoor scenario: the ATRV-Jr iRobot platform of partner PIAP with integrated sensors from partners UoR, SHU and IES. The final system employs two processing units (on-board robot PC and dual-core laptop) managing the following sensory information: sonar array, image monocular and pan-tilt camera, tilt and laser range finder, odometry and chemical readings, in semi-autonomous modes (navigation and remote operation). At any given time we have at least 4 streams of wireless transmitted data.

The VIEW-FINDER project

In the event of an emergency, due to a fire or other crisis, a necessary but time consuming pre-requisite, that could delay the real rescue operation, is to establish whether the ground can be entered safely by human emergency workers. The objective of the VIEW-FINDER project is to develop robots which have the primary task of gathering data. The robots are equipped with sensors that continually detect the presence of chemicals and, in parallel, stereo/mono image and (sporadically) ladar data are collected and forwarded to an ergonomically designed base station. The project comprises of two scenarios: indoor and outdoor.

Objective

The VIEW-FINDER project is a European-Union, Framework-VI funded program (Project Number 045541).

VIEW-FINDER was a field (mobile) robotics project, consisting of 9 European partners, that investigated the use of semi-autonomous mobile robot platforms to establish ground safety in the aftermath of fire incidents. The primary aim was to gather data (visual, environmental and chemical) to assist fire rescue personnel after a disaster has occured. A base station combined gathered information with information retrieved from the large scale GMES-information bases.

This project addressed issues relating to 2.5D map building, localisation and reconstruction; interfacing local command information with external sources; autonomous robot navigation and human-robot interfaces (base-station). Partners PIAP, UoR, SHU and IES were pre-dominantly involved in the indoor scenario and RMA, DUTH predominately involved in the outdoor scenario; with SAS and SyFire being involved in both.

The developed VIEW-FINDER system was a semi-autonomous system; the individual robot-sensors operate autonomously within the limits of the task assigned to them. That is, they autonomously navigate from two assigned points by planning their path and avoid obstacles whilst inspecting the area. Henceforth, central operations control assigns tasks to the robots and monitors their execution, with the ability to intervene at any given time. Inasmuch, central operations control has the means to renew task assignments or provide further details on tasks of the ground robot. System-human interactions at the central operations control were facilitated through multi modal interfaces, in which graphical displays play an important but not exclusive role.

Although the robots have the ability to operate autonomously, human operators monitor the robots' processes and send high level task requests, as well as low level commands, through the human-computer interface to some nodes of the ground system. The human-computer interface (base station) had to ensure that a human supervisor and human intervener on the ground, are provided with a reduced yet relevant overview of the area under investigation including the robots and human rescue workers therein.

The project was coordinated by the Materials and Engineering Research Institute at Sheffield Hallam University and officially ended on 30th November 2009, with final review, reports and demos scheduled for the 18 and 19 Jan. 2010.
