Interesting designs for Rescue Robots – Part 2

Professor Dr. Satoshi Tadokoro from the Tohoku University  presents his ASC. ASC is an search camera for usage in emergency situations and stands for Active Scope Camera. In basic it is a flexible endoscope which is able to move by it self. With the help of vibrating inclined cilia this endoscope can like a caterpillar crawl into smallest voids (>30 mm). Its maximum speed is 47 mm/s and the operating range is 8 m. This allows rescue workers to search in rubbles for victims or checking the structure of it.

The following video shows Professor Dr. Satoshi Tadokoro at the Tokyo International Fire and Safety Exhibition 2008 presenting the ASC.

During the Collapse of the Historical Archive of the City of Cologne (March 2009),  Professor Dr. Satoshi Tadokoro, Professor Dr. Robin R. Murphy (Texas A&M University), Clint Arnett (Project Coordinator for Urban Search and Rescue in TEEX), members of the Fraunhofer Institute for Intelligent Analysis and Information Systems (IAIS) were trying to support the local fire department. Therefore I was able to test the ASC which was in use during this disaster.

The ASC performs extremely well. It can crawl in a reasonable speed into the rubble and is (after a little training) easy to use. But the biggest problem is the user interface. The ASC camera system does not compensated tilting or turning if the „robot“ does flip/turn over, which happens quite often. Hence, it is hard for the Operator to keep track of the orientation. In addition the opening angle of the camera is extreme small, which does even more handicap the situational awareness.

Ever wanted to individualize your NXT a bit more?

Now you can buy the Roberta adhesive foils for Lego Mindstorms NXT (design by Ashley A. Green) at Technik LPE and coulourise your NXT the way you want. The foils are wipeable, heavy-duty and removable.

FAIR Libary is online

As we have already reported is the „Fraunhofer Autonomous Intelligent Robotics Devices“ Library now open source and available at the sourceforge project „OpenVolksBot„. In addition we can know report some more details on it.

  • The FAIRlib is now organized as several Eclipse-Project (fairAlgorithm, fairCore, fairDevices, fairGraphics, fairTestAlgorithm, fairTestCore, fairTestDevices and fairTestGraphics). This allows an easy extending and compiling the projects and minimizes the cross dependencies.
  • The dependences  are listed in the ReadMe and can be auto installed by using the script „apt-get-fair“
  • A way of easy installing is given by the script „install-fair„
  • The current version is tested on the Ubuntu 9.10 (64-Bit) ,  but will also work on other OS (by side of auto solving the dependences)
  • Fair is published under the CC-by-sa-nc License .

So now we all can reuse and cooperated in a create library, instead of reinventing the „wheel“ again and again. 😉

Open source is FAIR – IAIS released the „Fraunhofer Autonomous Intelligent Robotics Devices Library“ as open source

Developing and programming robotic systems can sometimes be an unsatisfying task. This feeling is mostly not related to problems that occur during „high level“ problem solving. It is mostly appearing if you try to get the system it self up and running. So tools and solutions are needed to help us to overcome these initialization barriers.

The Fraunhofer Institute for Intelligent Analysis and Information Systems or for short Fraunhofer IAIS, does now offer a special computer library that can support the developer to get a width field of sensors and actors up and running. In addition it includes a various number of algorithmic for every day robotic problems like Simultaneous Localization And Mapping (SLAM) or image processing. The so called „Fraunhofer Autonomous Intelligent Robotics Devices Library“ or for short FAIR library, is a C/C++ development library which is actively used in the VolksBot® projects and is released as open source project under the GNU-license Creative Commons.

FAIRlib is soon available at the sourceforge project „OpenVolksBot„.

Updated: The initail version is now available (see also here) and is published under the CC-by-sa-nc.

RobotsBlog is alive

RobotsBlog is a new blog focusing on robot topics. It will included news, discussions, articles, and links around the wide field of robotic and AI.

We, the authors, are an international team of junior researchers and actively involved in robotics. And so we are every day seeing the challenging problems and extreme nice solutions and we will try to share as much as possible with you. Our hope is that this platform will help all of us to sort and structure the wide field of robotics a little bit so that other researchers, students and every interested person can maximize their personal benefit which are archival by robotics.

And now it is time to present you some of our previous work.

The first video is showing some test runs of an Unmanned Aerial Vehicle or for short UAV, which is currently tested by the Fraunhofer IAIS.

Unmanned aerial vehicle

The second video shows a autonomous ground base robot using its docking station. The robot does base on a ProfiBot system and is searching autonomously for its docking station if it is needed. After finding it is performing a docking maneuver and charges it batteries.

The next video shows some tests results derived from a computer vision system that is used to detected character based landmarks in the environment. This behavior was needed to participated at the SICK robot day 2009 which we succesfully have done.

So thats all for the starting, new updates are coming and we hope to see you soon again.
