With the 2018 hurricane season just weeks away, the independent not-for-profit Center for Robot-Assisted Search and Rescue (CRASAR) announced the first ever Disaster Robotics Awards. Awards were announced for the 2018 Ground, Aerial, and Marine Rescue Robots of the Year on April 14, 2018 during a National Robotics Week ceremony at SEAD Gallery in Bryan, TX.

CRASAR’s 2018 Aerial Rescue Robot of the Year is the DJI Mavic Pro. With a price tag of $1,000, experts found this drone was able to do everything they needed. Because batteries are expensive, the low price and the ability to recharge using a car charger are particularly important, as is the stabilizing camera with pan and tilt. The review team also noted DJI Mavic Pro’s first-person view, as well as programmed views provide the option of broad, NASA-style tiled mapping if needed. Most importantly, DJI Mavic proved itself a workhorse among responders and quickly became the tool of choice, flying 78 of the 112 flights during CRASAR’s Hurricane Harvey response and just weeks later, 247 of 247 flights when they responded to Hurricane Irma.

Another workhorse among the 2018 honorees is the 2018 Marine Rescue Robot of the Year, Hydronalix EMILY. Among the most used by lifeguards worldwide, this water-based robot boat has the ability to run rescue lines to people in distress and the capacity for five to eight people to hang on while being towed to safety. These features have made surfboard-sized EMILY a favorite among lifeguards in both routine and large-scale water rescues, including refugee rescues along the migrant route in the Aegean Sea.

A lesser known but very promising terrestrial robot captured the win as the 2018 Ground Rescue Robot of the Year. Carnegie Melon University’s aptly named Snakebot can propel itself into the smallest of spaces, allowing rescuers to search for signs of life where dogs and people cannot reach. The 2017 Mexico City earthquake marked the first use of Snakebot in the response phase of a disaster operation.

“These robots enable life-saving decision making for responders and emergency managers,” Murphy says. “Rescue decisions and critical infrastructure decisions during that response phase are made very rapidly based on the best available information at the time and these robots, well-deployed with the right teams of operators and experts, are getting key information to decision makers so they can save lives and efficiently manage risk.”

Spearheaded by internationally renowned Disaster Roboticist Dr. Robin Murphy, the Disaster Robotics Awards were created to raise awareness of the role and value of robots for disaster response and help prepare responders to put these resources to work in both routine response and disasters.

“The goal of the Disaster Robotics Awards is twofold,” Murphy explains. “One, we are letting people know what’s working and why. Two, we want to get people thinking about the next disaster.”

The ceremony also included awards and acknowledgements. Educator of the Year went to David Merrick at the FSU Center for Disaster Risk Policy, for his work in developing and offering classes in small UAS aimed specifically for the needs of emergency professionals. One of the courses Is now available online at https://tinyurl.com/suas-course. Agency Partner of the Year went to Fort Bend County Office of Emergency Management for partnership on the Hurricane Harvey preparations, response, and recovery activities. The Service Award was awarded to Justin Adams who coordinated CRASAR operations as well as served as the Air Operations Chief for manned and unmanned operations for Fort Bend County during Harvey, then was CRASAR operations for Hurricane Irma, and deployed a third time to Hurricane Maria for three weeks.

Hurricane season begins June 1 and experts are anticipating a strong season of storms again in 2018. Murphy and her colleagues based the 2018 Disaster Robotics Awards on what robots worked well for responders over the last year. The CRASAR team documented robot use in response to hurricanes Harvey, Irma, and Maria, the Mexico City earthquake, and water rescues of Syrian boat refugees and elsewhere, gathering data regarding number, duration and nature of deployment. With these insights into what robots work best for responder, the 2018 honorees were selected.

While the awards recognize the contribution of robots in disaster response over the last year, CRASAR’s insights into the value of and best practices for robots in disaster response date back to the first use of robots in disaster response at the World Trade Center in the aftermath of the September 11th attacks. Murphy was on hand in New York and has been deploying robots in disaster response globally ever since. Through her work with both CRASAR and the Humanitarian Robotics and AI Laboratory in Texas A&M University’s Computer Science and Engineering Department, Murphy and colleagues continue to promote best practices and offer support to responders seeking the benefits of disaster robots.

Our hearts go out to the victims, their families, and the responders in Mexico. CRASAR has not been contacted about robots but this blog may be of use in thinking about how to use robots.

Ground, aerial, and marine robots have been used in several earthquakes. A good overview of ground robots for structural collapse is at https://www.youtube.com/watch?v=5Cm2bGlUjbQ. It’s an older documentary but all the issues and gear are still the same.

Small unmanned aerial vehicles are probably everyone’s first thought for earthquakes, in part to map out the extent of the damage. They can also be used to help responders determine the shortest, most debris-free route to locations or interest.  For the reconstruction and recovery phases, UAS have been used to fly around and in large buildings that are suspected of being too dangerous for structural specialists to enter and assess the risk of further collapse- for example the cathedrals in Canterbury NZ, Mirandola ,Italy, and Amatrice, Italy.  After the Tohoku earthquake, many experts pointed out that UAVs should be used to determine the state of hospitals- both whether the hospital is still functional but also if it is being overwhelmed by patients.

Ground robots also have a role. An earthquake may cause buildings to completely collapse where there are no voids that a responder can get into. The general strategy is to use a canine team to determine if there are survivors in the rubble (dogs can tell if the person is still alive). Typically a boroscope or a camera on a wand is inserted to try to see if they can locate the survivors and also get a sense of the best was to remove material to get to them.  The boroscope or a camara on a wand can only go about 18 feet into the rubble, depending on how twisty the void is. In a major building collapse, survivors may be much further, which is why small, shoe-box sized robots such as an Inuktun VGTV may be used. The “cameras on tracks” robots can pull themselves into the rubble and also change shape to help get into tight spots.  These small robots will usually be tethered, with the tether acting as a belay line and the tether preventing loss of signal.

Some interesting robots are the snake robots being developed by Howie Choset at CMU and the Active Scope Camera caterpillar robot being developed by Olympus in conjunction with Japanese researchers led by Satoshi Tadokoro. The ASC was used at the Jacksonville building collapse in 2007.

Bigger ground robots, such as those used at Fukushima, can be used in bigger buildings but gepnerally can’t see the ceilings, which is usually very important and happened the New Zealand earthquake. They can’t go into small voids and may be too heavy- they could cause delicately balanced rubble to further collapse and kill a survivor underneath.

Marine robots, especially ROVs, are important as was seen in the Haiti earthquake and Tohoku earthquake and tsunami. The earthquake may have changed the shipping channels, damaged bridges and ports, and put debris in unexpected places. Thus shipping is stopped until the shipping channels are cleared- and as was seen at Haiti it’s hard to feed a country with one airport. Shipping is extremely important for getting relief supplies in.

There are more details in the case studies in Disaster Robotics  and the Springer Handbook of Robotics on what robots have been used and particular strategies. All of us are happy to answer questions. We wish everyone the best on this terrible event.

A major update from our earlier post    CRASAR was at Hurricane Irma supporting Roboticists Without Borders’ member Florida State University Center for Disaster Risk Policy deployment to Collier County, Florida. The CDRP effort was led by David Merrick, CDRP director, with Justin Adams, Kovar and Associates, who led the CRASAR Harvey response serving as his deputy. Collier County is in southern Florida near Naples and Marco Island. This is familiar territory to CRASAR, who responded to Hurricane Wilma in 2005 at Marco Island, sending out the first known use of unmanned marine vehicles. The county was exposed to severe wind damage and flooding from Irma which passed over as a Category 3 hurricane on September 10. The teams demobilized on September 16, with last flights on September 15.  Six UAS pilots flew 247 imaging flights covering over 491 critical infrastructure targets, as well as provided overwatch for FL Task Force 8 and made multiple maps. The flights started on September 11 and surpassed the record of 119 mission flights for public officials during a disaster set at Hurricane Harvey. FSU and Texas A&M plan to offer a joint day-long short course on small UAS for emergency management on October 21, expanding the course that they have taught at the Florida Governors Hurricane Conference in May 2017 and for Los Angeles County Fire Rescue last week. Contact Robin Murphy for more information about the Irma deployment and the upcoming course.

The FSU CDRP team under the direction of David Merrick was a major component of CRASAR’s record setting small UAS Hurricane Harvey response, leaving Texas with two days to prepare and predeploy for Irma. The use of small UAS at Irma initially followed a similar pattern to Hurricane Harvey, with UAS being used to assist with rapidly conducting search and rescue operations and determining the best route for US&R teams to reach people at risk but now has shifted to determining the state of over 1,500 critical infrastructure targets in the county. These targets, which include bridges and waste water treating stations,  impact the restoration of services and the economic recovery of the regions. The use of small UAS has significantly sped up the process, provide more complete assessment of all sides of a target, and multiple targets can be examined on one flight.

The FSU CDRP-led teams consist of pilots, data managers, platforms, and the RESPOND-R mobile lab. The teams are from FSU, Kovar and Associates, and CRASAR. The teams have 7 pilots with a fleet of 20 platforms including the DJI Mavic, DJI M600 Pro, Inspire, Intel Falcon 8, Disco, Phantom 3, and PrecisionHawk Lancaster rev 5. The teams are using the lessons learned at Harvey to improve rapid sortie planning, team situation awareness, and streamlining data management. Data is being collected by CRASAR and FSU from both deployments to permit developers to build better UAS optimized for the wind and operations tempo in a disaster and user interfaces that facilitate the data-to-decision process enabling county emergency management experts to rapidly get the right information and make good decisions. The data will also support the creation of  new visualization tools for responders, enabling them to sort through terabytes of aerial imagery, and serve as a foundation for machine learning and computer vision algorithms to process tetrabytes of data.

The Irma response differs from the Harvey response in at least four key ways.

• the hurricane posed primarily wind damage with flooding as a secondary impact, whereas Harvey in Fort Bend County was primarily flooding from rainfall and then the risk of additional river flooding. This changed the style of search and rescue operations, especially as cellular coverage was affected and residents could not always call for help. The UAS teams assisted Florida Task Force 8 as the aerial view helped  the searchers determine where to go, which flooded house to inspect next, and to better coordinate operations. The wind damage in Irma made route clearing operations more important as downed trees could unpredictably be blocking roads as compared to flooding with tended to inundate specific areas and predicted from flood maps.
• the majority of missions are for critical infrastructure property damage assessment. These assessments were normally being done in person.  This is time consuming for driving to the site (including determining alternative routes) and then requires a person’s time to survey the target. In many cases, the inspector cannot see or get to all sides of a facility. While both manual and UAS inspection require the same amount of time to get to a target, the use of UAS is being shown to be faster than walking around and more complete as the UAS can fly around the target and also provide an birds’ eye view as well. For example, on Sept. 13, two 2-person UAS teams were able to document 97 infrastructure targets with 12 flights. Our initial look at our logs indicate an average of 16 minutes on-site for a mission– that’s stop the car, turn on the UAS, fly the mission, get back in the car. And a flight covers an average of 2 targets per flight. It’s hard to believe that a person can walk around a tank farm faster.
• A single flight (or sortie) at Irma typically covers multiple targets (an average of 2 targets), while at Harvey a single flight covered only one direct mission objective (though the aerial imagery was used to inform additional multiple emergency support functions).
• Operationally, the resident population and airspace traffic is less dense, with less manned assets flying in the region and the operations did not require a Temporary Flight Restriction for safety. The Irma teams have less challenges in planning flights to avoid flying over people and did not encounter self-deployed teams or hobbyists interfering with UAS flights for officials; these challenges were seen at Hurricane Harvey.
