Abstract and Figures

Mobile robots can be highly valuable tools in Urban Rescue Missions, inspecting collapsed buildings, assessing the situation, looking for victims and establishing a first contact to them. At the International University Bremen (IUB), rescue robots for these tasks are developed since 2001. All components of the robots, ranging from mechanics over computational hardware to all software levels have been to a large extent custom designed for the difficult task of rescue missions. The newly established rescue arena at IUB plays an important role in the development cycle of the robots. It provides the necessary complex and realistic test-scenario to provide feedback about the deficiencies of the robots and to allow the investigation of advanced algorithms, especially for control, localization and mapping.

Abstract
Mobile robots can be highly valuable tools in Urban
Rescue Missions, inspecting collapsed buildings, as-
sessing the situation, looking for victims and establish-
ing a first contact to them. At the International Uni-
versity Bremen (IUB), rescue robots for these tasks are
developed since 2001. All components of the robots,
ranging from mechanics over computational hardware
to all software levels have been to a large extent custom
designed for the difficult task of rescue missions. The
newly established rescue arena at IUB plays an impor-
tant role in the development cycle of the robots. It pro-
vides the necessary complex and realistic test-scenario
to provide feedback about the deficiencies of the robots
and to allow the investigation of advanced algorithms,
especially for control, localization and mapping.

1 Overview
IUB robotics is actively working in the domain of
rescue robots since 2001. The team has already par-
ticipated in RoboCup 2002 in Fukuoka and RoboCup
2003 in Padua [BCK04, BKR+02]. The team ended
on both occasions on a 4th place in the ranking. Fur-
thermore, the team won in 2003 a technical award for
its mapping capabilities [CKB03]. The robot hard-
ware development is based on the CubeSystem for fast
robot prototyping [Bir04, BKW98].
The goal of the IUB team is to get within the next
two years to a status where the overall system can be
launched and used by rescue workers who have un-
dergone hardly any training for the system. Crucial
issues are the turn-key start-up of the robots and an
intuitive user-interface of the operator’s console. For
this purpose, all software components are integrated in
a general framework that supports adjustable auton-
omy. The annual participation in the RoboCup com-
petitions proved to be a crucial element in the devel-
opment cycles of the robots. To achieve the ambitious
goal of getting fieldable system, it became clear that
a more permanent evaluation basis is needed. Hence,
a rescue arena has been set up at IUB for testing and
training purposes.
The arena covers three different levels, the so-called
yellow, red, and the orange zone. This approach is
modeled after the test arena design from the Ameri-
can National Institute for Standards and Technology
(NIST), which is based on data from real catastro-
phes. This approach of the NIST arenas has also been
already used in the RoboCup competitions from 2001
on. Yellow models an intact building structure with
a normal office or home interior that has been mildly
affected by the disaster. In the orange zone, the ef-
fects to the interior as well as to the building itself are
much more severe. Last but not least, the red zone
is a model of a pancake collapse with large amount of
rubble and highly instable structures. The IUB arena
is an extension of the concepts of the NIST arena. One
particular feature is its compactness as it is based on

zone.

zone.

arena at the RoboCup 2003 competition.

a high bay racking system. This allows to have a large
floor-space and many different levels. The arena has
a footprint of 5.60m by 4.70m and it is approximately
6m high. It has 3 main floors and several intermediate
floors, which are interconnected.

... For this reason we implemented some well known optimization algorithms and we compared them with a new iterative optimization procedure we recently developed [6]. All the results we provide are not obtained via simulations, but from data collected while running our robots in the newly setup IUB rescue arena [3]. In the following we will describe the robots we developed for rescue robotics and that has been tested in the robocup rescue competition. ...

We illustrate our progresses in developing multi-robot systems to be used for mapping in rescue scenarios. The problem we are currently investigating is to combine poor quality multiple maps produced by different robots into a single map to be used by human operators. In particular we motivate our approach and we illustrate the different techniques we implemented and that are at the moment being compared.
... The following list gives an overview of their locations and the years of opening: The performance evaluation aspects described in this paper are based on work at the test site at the Jacobs University Bremen. This test site consists of two parts as shown in figures 1 and 2. The first arena is available since spring 2004 at Jacobs [4]. It is based on a high-bay-racking system. ...

The Jacobs University Bremen features a special test site for mobile robots. It consists of two large arenas with test elements, which are particularly suited to evaluate the performance of systems operating in challenging domains like Security, Safety, and Rescue Robotics (SSRR). The site is one of only six worldwide, which has been established in close cooperation with the US National Institute of Standards and Technology (NIST). This paper presents the Jacobs arenas and a set of metrics for evaluating the mobility, sensing capability, and onboard intelligence of robots. The tests are illustrated by using a Jacobs rescue robot, which is equipped with state of the art sensors. The relative strengths and weaknesses of these sensors are evaluated in a variety of situations; many of them are typically encountered in SSRR applications.
... These properties can be easily transferred to the parameters controlling the simulated range finder. We first run the simulated robot into the model of the IUB rescue arena [15] and gathered the data produced by the simulated proximity range finder. Then, we run the real robot into the real arena and collected the same data. ...

USARSim is a high fidelity robot simulation tool based on a commercial game engine. We illustrate the overall structure of the simulator and we argue about its use as a bridging tool between the RoboCupRescue Real Robot League and the RoboCupRescue Simulation League. In particular we show some results concerning the validation of the system. Algorithms useful for the search and rescue task have been developed in the simulator and then executed on real robots providing encouraging results.

The default solution for mobile robot communication is RF- networking, typically based on one of the IEEE 802.11 standards also known as WLAN technology. Radio communication frees the robots from umbilical cords. But it suers from several significant drawbacks, espe- cially limited bandwidth and range. The limitations of both aspects are in addition hard to predict as they are strongly dependent on environment conditions. An outdoor RF-link may easily cover 100m over a line-of-sight with full bandwidth. In an indoor environment, the range often drops to a few rooms. Walls made of hardened concrete even completely block the communication. Driven by a concrete application scenario where com- munication is vital, namely robot rescue, we developed a communication system based on glassfibre links. The system provides 100MBit ethernet connections over up to 100m in its default configuration. The glassfibres provide high bandwidth, they are very lightweight and thin, and they can take a lot of stress, much more than normal copper cable. The glassfiber links are deployed from the mobile robot via a cable drum. The system is based on media converters at both ends. One of them is integrated on the drum, thus allowing the usage of inexpensive wired sliprings. The glassfibre system turned out to be very performant and reliable, both in operation in the challenging environment of rescue robotics as well as in concrete experiments.

The CubeSystem is a collection of hardware- and software-components for fast robot prototyping. The main goal of the CubeSystem project is to provide an open source collection of generic building blocks that can be freely combined into an application. This paper describes the first release of the CubeSystem, that evolved in more than five years of research and development. The benefits of the CubeSystem are illustrated by several applications, ranging from educational activities to industrial projects.
