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, after a fire or other crisis event has occured, a necessary but time consuming pre-requisite, that could delay the real rescue operation, is to establish whether the ground can be accessed / entered safely by human emergency workers. This was the context under which the project was initiated.

General Description

Viewfinder Logo
EU flagCORDIS logoIST logo

VIEW-FINDER was a field (mobile) robotics project (European-Union, Framework-VI: Project Number 045541), 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 project was coordinated by the Materials and Engineering Research Institute at Sheffield Hallam University and officially ended on 30th November 2009, final review, reports and demos took place on the 18th Jan. 2010. The review that took place on the 19th Jan 2010 judged the project as 'successful'.

The objective of the VIEW-FINDER project was to develop robots which have the primary task of gathering data to assist the human interveners in taking informed decisions prior to entering either an indoor or outdoor area. Thus 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 the gathered information with information retrieved from the large scale GMES-information bases. Issues addressed, related 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.

System description

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, the remote central operations control unit 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 had 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 comprised of two scenarios: indoor and outdoor, with a corresponding robot platform for each scenario. The indoor scenario used a heavily modified ATRV junior robot platform that used to be available from iRobot and a purpose built outdoor robot based on the RoboSoft mobile platforms.

The indoor robot was equipped with two laser range finders, one of which was attached to a tilt unit for providing 3D acquisition, a front sonar array, a pan-tilt-zoom camera, a chemical sensor array and a long range wireless communication device. Apart from the existing robot processing unit (Ubuntu 8.04), there were added another two processing units (one with winXP and one with Ubuntu 8.10). The low level control of the robot and behaviour (e.g. obstacle avoidance and navigation) was achieved via the pre-existing processing unit whilst the data processing for the purposes of mapping and localisation were placed on the additional linux unit. The winXP unit was used whenever windows specific (proprietary) software items had to be deployed. All robot collected data were forwarded to an ergonomically designed base station.

The software platform for the robots was as follows:

  • indoor robot (both WinXP and Ubuntu 8.10) was a hybrid that used Player 2.1.2 and Corba as the robot hardware communication layer and IES Mailman for wireless data transmission layer (UDP/IP; packing, fragmentation) to the base station
  • outdoor robot used solely WinXP and Corba through the RMA partner's modification layer known as Coroba

In both cases, great effort was dedicated on the integration of hardware and software modules.
