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.
