Welcome to the Center for Robot-Assisted Search and Rescue (CRASAR) at Texas A&M University

CRASAR is a Texas A&M Engineering Experiment Station Center whose mission is to improve disaster preparedness, prevention, response, and recovery through the development and adoption of robots and related technologies. Its goal is to create a “community of practice” throughout the world for rescue robots that motivates fundamental research, supports technology transfer, and educates students, response professionals, and the public. CRASAR is a dynamic mix of university researchers, industry, and responders.

CRASAR has participated in 15 of the 35 documented deployments of disaster robots throughout the world and have formally analyzed 9 others, providing a comprehensive archive of rescue robots in practice. Our industry partners and funding agencies make a wide range of small land, sea, and air robots available for use by responders at no charge through the Roboticists Without Borders program. Our human-robot crew organization and protocols developed first for UGVs, where studies show a 9 times increase in team performance, and then extended for small UAVs during our flights at Hurricane Katrina has been adopted by Italian and German UAV response teams and was used by the Westinghouse team for the use of the Honeywell T-Hawk at the Fukushima nuclear accident.

CRASAR helps organize and sponsor conferences such as the annual IEEE Safety Security Rescue Robotics conference and workshops such as the recent NSF-JST-NIST Workshop on Rescue Robots.

Resources Including Guides and Best Practices for Small UAVs at Disasters

A good overview of rescue robotics is in Disaster Robotics by Robin Murphy (MIT Press, Amazon, and Kindle)- Disaster Robotics is for both practitioners and researchers. It covers 34 deployments worldwide from 2001 through 2013, describes the missions, and next discusses the specific applications and lessons learned for ground (Chapter 3), aerial (Chapter 4), and marine (Chapter 5) vehicles, and then ends with recommendations on how to conduct deployments and field work (Chapter 6). Disaster Robotics won the 2014 PROSE honorable mention for best engineering and science writing.

Here are helpful 1 page guides and best practices for small unmanned aerial systems that have been incorporated into United Nations humanitarian standards and are continuing to evolve:

Italian Earthquake: Recommendations for using ground and aerial robots for immediate lifesaving

Our thoughts and prayers go out to the Italian people impacted by the earthquake. We’ve reached out to colleagues in Italy in case any of us here can be of assistance. Below is a general overview of what might be useful and why.

From the scanty news reports in the US, my guess is that this event will favor the use of small tethered ground robots for locating survivors in rubble based on the case studies from 9/11 World Trade Center, Cologne Archives collapse, Berkman Plaza collapse Prospect Towers collapse, L’aquila earthquake, Mirandola earthquake, and multiple mine disasters worldwide (see Disaster Robotics, MIT Press, 2014 for those case studies). UAVs may be of value in estimating extent, ascertaining whether roads are open or can be easily cleared to allow responders rapid access, and general damage assessment and recovery operations (as per Nepal and Chile), but probably not for direct life saving- though I could be wrong.

“Small”  as in pipe inspection robots- not a bomb squad robot like the Packbots used at Fukushima- because if a person or dog could get into a void to reach a trapped person, they probably would despite the personal risk. A tether is useful because it solves wireless and power problems- but more importantly any entry would likely be from the top of the structure or the upper parts, so the robot has to rappel down.

A video camera, color, is essential. Thermal cameras may be of use initially but are very hard to use for navigation in confined spaces. So I wouldn’t recommend thermal by itself, rather as a second camera. The value of a thermal camera goes away after a few days because decomposing bodies present a heat signature. Navigation gets harder as small protrusion become the same temperature as the surroundings.

A robot with 2-way audio will be valuable because the operator can call out and listen for sounds of survivors, then medical experts can talk with the victims. But even just a speaker or a microphone by itself can be useful.

Should someone find a survivor, a small tube can be attached to the robot to provide water to a trapped victim- hook up the end to an aquarium or koi pond pump. (This is a great solution worked out by Eric Rasmussen and we tested with the USMC CBIRF unite.) The robot can probably maneuver and bring a small payloads- a radio, a space blanket, power bars (assuming they aren’t severely injured). LACoFD does so many confined space rescues, they can have a kit the size of a Pringles can for trying to give to people trapped in caves and culverts.
