Drone Helps Rescue 2 Boys from Raging River

Two boys needed to be rescued from the raging Little Androscoggin River in Maine after their tube overturned Tuesday. Only one of them was wearing a life jacket. Frank Roma, chief of the Auburn fire department, wanted to get that boy a life jacket before attempting the rescue. The water was rough, and rescuers had a hard time getting to the boys, so they used Roma’s personal drone to deliver a life jacket and a safety line to the boys.

“We wanted to make sure we got a life jacket on that second child so that if they did fall in the water we could catch them downstream,” said Roma. “We used the drone to fly a tag line out to the young man that was on the rock, we instructed him to untie and to pull life jacket over to him.”

Robot boats as swift water rescuers, not just for critical infrastructure and restoration/recovery operations anymore!

Grant Wilde and Gino Chacon observed the EMILY rescue boat, a new concept in disaster robotics. I have followed Tony Mulligan and his work with EMILY since 2012 and EMILY is really gaining acceptance. He demoed the boat this week during a swift water exercise (which our partners Austin Fire Department participated in- thanks Coitt for the directions!) The robot acts as a barrel-shaped life ring. An operator teleoperates EMILY to a victim in the water and the victim grabs it. The operator then uses the tether to pull EMILY and her cargo to safety.

We’ve been pinged many times by fire rescue teams about swift water rescue- though about the use of UAVs. Swift water has many challenges, one of which is that the rescue crew in their boat is at risk for being struck by debris speeding into them. The idea was the UAV could act as a spotter and help coordinate the safety of responders and victims alike. EMILY bypasses some of the challenge by eliminating the responder.
Grant and Gino are working a slightly smaller robot boat for shallow littoral areas, definitely not swift water, for radiation sampling for treaty verification, identifying flood vulnerable areas (with the Hazards Reduction and Recovery Center), and general environmental sampling. Some nuclear power plants or towns can be readily accessed by creeks even if roads are out. Dr. Josh Peschel, a former PhD student now at University of Illinois, is working with these marine platforms to better understand water management.

Stop Laughing at Those Clumsy Humanoid Robots

The Humanoid Robot, built like a linebacker with an oversized head, tiptoes on two feet through the dirt. It’s free of any wires. It’s unleashed—but it’s now wavering. They were all part of a competition in Pomona, California put on by Darpa, the far-out research wing of the Pentagon. After the Fukushima disaster in 2011, Darpa set out to encourage the development of robots that can assist in similar catastrophes: machines capable of working where humans dare not go. And so the yearly Darpa Robotics Challenge was born.

To explore something like a contaminated nuclear reactor, a robot would have to conquer not only piles of rubble in the facility, but also be able to open doors and climb stairs and ladders. In a human-designed space, the thinking goes, a humanoid robot would be best equipped to handle the job. And indeed, for all their clumsiness, the semi-autonomous robots (human operators still do much of the controlling in the challenge) passed some impressive tests, including driving an ATV.

The thing is, relief workers have had operational “tracked” robots for 15 years that roll along on tank-like treads. They even helped out in the aftermath of Fukushima, and still run tests there to this day. Bipedal humanoids, on the other hand, have never gotten near an actual disaster. They’re expensive, and you don’t have to be a physicist to notice these robots are top heavy.

So why even bother developing bipeds? Well, when Darpa’s handing out $2 million for first place in its challenge, building a walking robot that drives ATVs must seem like a sweet deal.

N.C. State team pioneers backpack-wearing cockroaches that can explore disaster areas

Researchers at N.C. State are developing technology that equips cockroaches to enter disaster areas and send back information for search-and-rescue missions. The insects carry backpacks that contain a small microphone and radio transmitter.

These enhanced insects – dubbed biobots or cyborgs – have been developed by Alper Bozkurt, an assistant professor of electrical and computer engineering at N.C. State, and others over the past eight years. Working initially with moths and, later, cockroaches, the scientists equipped the insects to pick up sounds too distant or faint to be heard outside the rubble.

Another facet of the technology allows the insects also to send signals to one another. “It’s a neighbor-to-neighbor interaction that allows someone to build a map,” explained Edgar Lobaton, a robotics engineer and assistant professor in NCSU’s Department of Electrical and Computer Engineering. “These little agents move around and continuously communicate with each other by sending out radio signals. We are learning to take this information, put it in a computer, and create a map of the area.”

Researchers make a robot with other bots

Engineers have created a modular spider robot that has snake bots as feet. It could be reconfigured to meet almost any user requirement and could also be useful in search and rescue operations. Carnegie Mellon University’s latest robot is called Snake Monster, however, with six legs, it looks more like an insect than a snake. But it really doesn’t matter what you call it, says its inventor, Howie Choset – the whole point of the project is to make modular robots that can easily be reconfigured to meet a user’s needs.

The Defense Advanced Research Projects Agency sponsored this work through its Maximum Mobility and Manipulation (M3) program, which focuses on ways to design and build robots more rapidly and enhance their ability to manipulate objects and move in natural environments. Snake Monster, as well as some of Choset’s other robots, will be demonstrated at the finals of the DARPA Robotics Challenge in June.

Russia wants to develop search-and-rescue robots for the Arctic

As Russia focuses on militarizing its Arctic region, the Kremlin is trying to develop military technology needed to operate in one of the world’s harshest environments. Russian military planners are now setting their sights on the development of Arctic rescue robots.

Admiral Victor Chirkov, the head of the Russian Navy, has called for the development and construction of “Arctic underwater search and rescue robots,” Newsweek reports citing Itar-Tass, a state-owned Russian media organization. The robots would be designed to withstand difficult Arctic conditions and cold temperatures.

The robots would be kept aboard Russian icebreakers and other maritime vessels to assist in search-and-rescue missions. They would save human rescuers from having to operate in waters whose temperates average a chilly (and deadly) 28-29 degrees Fahrenheit.

Vanuatu: How disaster robots have helped in 12 similar events and might help there

I’m here at the UN World Disaster Conference where word of the destruction in Vanuata is coming in and our thoughts and prayers go to out the victims and families. It sounds like the effort is on humanitarian relief.  I’m not seeing any discussion of mitigation/response/recovery of critical infrastructure, which is the historical focus of disaster robotics. Here’s some information on how robots have helped in 12 similar disasters.

Small unmanned aerial systems have been used by rescue authorities in 8 storm or flooding events: Hurricane Katrina, Hurricane Wilma, Typhoon Morakot (Taiwan),  Thailand floods, Typhoon Haiyan (Philippines), Boulder Colorado floods, SR530 mudslide and flood, Serbia floods. UAS are most often used for rapid reconnaissance and mapping of the extent of devastation, condition of transportation routes and what areas are cut off, power lines, and general hydrological and geological mitigation needed to predict, contain, or drain water, etc.

Small marine vehicles have been used by rescue authorities in 3 storm and flooding events: Hurricane Wilma, Hurricane Ike, Tohoku tsunami (Japan).  They are mostly used to identify the state of bridges and ports, debris that is blocking ports or polluting fishing areas, and for the recovery of victims that were washed away into the sea. Plus they were used at the Haiti earthquake to clear underwater debris from the port to allow humanitarian relief supplies to be shipped in (it’s hard to feed a country via planes into a single airport). In Japan, the use of marine vehicles by the IRS-CRASAR team was credited for re-opening the Minamisaniruku new port 6 months earlier than would have been possible with manual divers and in time for the key salmon fishing season.

Unmanned ground robots are almost never used because commercial buildings rarely collapse in these conditions, it is mostly individual homes.

Tohoku earthquake anniversity and UN World Conference on Disaster Risk Reduction

wcdrr-logo-desktop-v3.0It is the 4th anniversary of the Tohoku earthquake and I am en route to Sendai where the United Nations World Conference on Disaster Risk Reduction. It is sobering to think that over 18,000 people died and that the great nation of Japan is still recovering.  It makes it even more appropriate for Japan to host the conference and at Sendai. I look forward to seeing my colleagues from the International Rescue Systems Institute who we worked side-by-side with unmanned marine vehicles.

I will be giving an invited talk on the current state and achievement of  disaster robotics during the Public Forum. In looking back between 2011 and now, the biggest surprise is that unmanned marine vehicles are not being used as much as I would have thought. The tsunami response and recovery showed the efficacy of these tools and how the can do in 4 hours what it take divers weeks to do (if they are available). There’s no surprise in that unmanned systems are being used more frequently! I’ll post the my findings when I give my talk– no spoilers!
