Hurricane Sandy: watching and prepping for SSRR

A post from robots.net reminded me that I hadn’t updated the blog about Hurricane Sandy. We have not been called and really didn’t expect to be. Sandy hit the NJ/NY area- home turf to Jim Bastan and NJ-TF1, the US&R task force that has been aggressively adopting robots.  They fielded the ground robots at the Prospect Towers collapse and also have been experimenting with UAVs. Likewise FDNY and NYPD have access to a wide set of technologies through the DHS National Urban Science and Technology lab.

Remember: Roboticists Without Borders patch to pointers to where robots have/are being used! Help me keep the list of robots and disasters growing!

We do expect to assist with recovery efforts such as what we did in Japan, especially with underwater assessment. In the meantime, I am personally working on the finishing touches for the 10th IEEE International Symposium on Safety, Security, and Rescue Robots, which starts on Monday. I’m the general chair with Dr. Alex Kleiner, a fabulously talented researcher in Sweden,  serving as the conference chair organizing the 43 papers from 10 countries doing most of the real work!

A Decade of Rescue Robots Video out!

Check out our new video presented at IROS 2012 for the Jubilee video competition: http://youtu.be/QPQrKAYbQUQ. It shows the past ten years of rescue robots and CRASAR’s deployments.

Anniversary of 9/11 and human-robot interaction

It’s 9/11 and it is perhaps karma that I am at the NDIA Human-Systems Division Workshop- because the lesson learned at the WTC was that the robots were physically good enough, but the biggest area for improvement was the human-robot interaction. Check out Jenn Casper’s paper
at http://tinyurl.com/9dt4nrg – it’s one of the most highly cited papers in human-robot interaction.

Our thoughts and prayers remain with the families of the victims and all the people working in homeland security and homeland defense to prevent terrorism and eliminate the need for rescue robots for that particular application.

Iran Earthquake

The death toll for the latest Iranian earthquake appears to be settling in around 300 lives lost- a sad number. Iranian rescue roboticist and colleague Amir Soltanzadeh posted on facebook that most of the victims were in 1 story houses which were easy to search. This is where dogs excel- they can cover large areas, determining if there is a survivor in a house in minutes (or less), whereas a ground robot has no comparable sensors and would have to physically worm through the rubble to visually find a survivor- a process that takes time and energy (as in battery power is limited).  1 story houses are also easier to work with for extrication- a ground robot doesn’t offer much benefit.

Unmanned aerial vehicles may be the best initial choice of robots for disasters that pose extreme scales of distance and area– their first look can help professions prioritize the response and estimate the resources that will be needed. Together with social networking from those on the scene, professionals can get better information must faster.

The Iranian people are in our hearts and prayers and we are all grateful this earthquake was no where as bad as Bam.

Landslide in British Columbia: how robots can help in such events

The sad news of the mudslide in Canada is very similar to the 2005 La Conchita mudslide, described in this paper on rescue robots for mudslides, where CRASAR had its first post-World Trade Center deployment of rescue robots at the request of the Ventura County Fire Department. Mudslides are fluidized, so like water, the mud penetrates everything nook and crevice. Survivors are generally found in the collaterally damaged structures on the periphery rather than in the direct path. Small ground robots can be useful for trying to get into the crushed and twisted houses and buildings, either from the roof or from under the foundation. But robots and unattended ground sensros can also be useful for monitoring the mudslide- because the responders have to worry about the slide breaking loose and sliding more. Everyone had to evacuate La Conchita because of that. Work has been done by various groups to create unattended ground sensors that can be stuck in the ground  of sensitive areas and wirelessly report soil water content (hey– things are fluidizing here!) and movement (hey- I’m beginning to creep and shift, big movement may follow).  One idea is to use aerial robots to drop these networks of sensors in place after a disaster to help monitor. Otherwise, geologists have to periodically laboriously climb up (and hope not to trigger more slides) and take manual measurements. Our prayers go out to the families and the responders.

Below are pictures from La Conchita:

On the use of construction robots at the Elliot Lake Mall Collapse

Nice article here on the use of mining and construction robots at the mall collapse in Canada. However, the article’s promotion of heavy-duty machinery for search, versus for extrication, may be misplaced.

Our work at 15 disasters since 9/11 and documenting the other known responses strongly indicates that for the search phase, very small agile robots with 2-way audio are desirable. They are small enough to get into the irregular voids or be lowered in through the roof, they are light enough not to cause a secondary collapse, the can move around and get better viewpoints than with a search cam,  inexpensive, and easily transported (from the back of a truck into a backpack…).

A recent example of this is the Hackensack New Jersey Prospect Towers collapse where the NJ Task Force 1 and the UASI teams used Inuktun robots to search for survivors with a couple of hours of the incident. Inuktuns have about a 300 ft long tether, a search cam is usually only to penetrate 18 feet.

Big, heavy gear is certainly of great value for removing rubble, bracing structures, etc. It’s just not the same as small robots for search, finding and interacting with the victim until they are extracted (which can 4-10 hours).

Greg Walker and UAVs in Wired!

Greg Walker at University of Alaska Fairbanks- a great guy and UAV expert who was scheduled to go with to Minamisanriku last October- is in WIRED for using an Aeryon Scout UAV for chemical plant inspection.  Preventing disasters count as much as responding to them! Kudos!

News video: Our aerial and ground robots with Austin Police Department

We’ve had members of the Police Technology Unit of the Austin Police Department over to Disaster City twice to see our Dragan and AirRobot UAVs and our Packbot 510 and SUGV.  SPO Eric Cortez and his colleagues have been terrific in helping us learn more about how they would use these devices, what they look for in a disaster (which the new Dr. Josh Peschel worked on for his PhD),  and how fire rescue and police might share and coordinate. Here’s the link to the Austin Fox Channel video– one embarrassing aspect: Disaster City is a Texas Engineering Extension Service (TEEX)  facility not the Center for Robot-Assisted Search and Rescue.

75th Anniversary of the Hindenburg

The 75th anniversary of the Hindenburg disaster was yesterday, which leads me to a shout-out for New Jersey Task Force 1 which is housed at Lakehurst Naval Air Station in old blimp hangers within an easy stroll of the site of the fire (there’s a nice plaque marking the spot). New Jersey Task Force 1 was the first US team to adopt rescue robots, almost immediately after 9/11. They continue to explore new technologies such as new sensors and small UAVs. Keep up the good work!

Underground mine rescue communications

Juan Rojas has passed on this interesting article about a robot controlled with a through-the-ground wireless link and tested in an abandoned mine. Through the ground wireless is a Holy Grail of mine rescue so this appears to be a great step in the right direction!
