A building collapse is almost always terrible, a building collapse of a maternity ward is unthinkable. All of us send our thoughts and prayers to the families of this horrible event.
Although there is no news about any robots being used, robots were first used in disasters for commercial multi-story building collapses– notably the 9/11 World Trade Center. Commercial multi-story buildings present unique challenges for searching because the concrete floors can be densely pancaked in some areas with just inches of space and leave survivable voids in others.
Small robots like the shoe-boxed sized micro VGTV and micro Tracks by Inkutun were used the most at the WTC because they could go into the rubble where a person or dog could not fit and could go further than a camera on a wand. That is still the case, with small robots being used to go between tightly packed layers of rubble at the Berkman Plaza II collapse in Jacksonville (2007) and the Prospect Towers collapse in New Jersey (2010).
Bigger robots such as the IED robots like iRobot Packbot and QinetiQ Talon are often too big for the size of voids in the rubble of a pancake collapse. Really large, “maxi” robots such as the REMOTEC series are not only too big, but the weight poses a problem- as in they are so heavy they could cause a secondary collapse.
If anyone knows of other multi-story building collapses where robots were used, please let me know and a reference and I’ll send a CRASAR patch.
In the meantime, our thoughts and prayers to the families in Mexico…
There’s nothing like appearing on the home page of Emergency Management Magazine to trigger a “holy cow, I haven’t been keeping up the blog!” It’s been hugely busy here between working with students colleagues, and industry partners on
creating use cases for robots for Ebola and other infectious diseases with a grant from the National Science Foundation (Eric Rasmussen, MD FACP, and our medical director for Roboticists Without Borders is the co-PI),
prepping UAVs for an upcoming wilderness search and rescue exercise with Brazos Valley Search and Rescue (big shout out to the FAA and CSA for their help!),
prepping for the Robot Petting Zoo we are doing with the Field Innovation Team at SXSW to show off real robots used in real disasters,
getting to work with Prof. Howie Choset at CMU and Prof. Dan Goldman at Georgia Tech on burrowing robots through a National Robotics Initiative grant from NSF, and
teaching an class overload (add case studies of robots at disasters to undergrad robotics as part of my Faculty Fellow for Innovation in teaching award, plus the AggiE Challenge advised by Profs. Dylan Shell, Craig Marianno, and myself on creating ground and water robots to detect radiation )
So things are happening! Thank you for your donations that make it possible to bring robots to new venues such as wilderness search and rescue and public education events like the Robot Petting Zoo. Most of what we do is based on donations, so please donate here!
Humans have long admired the ability of cats to always land on their feet — known as the cat righting reflex. The flexible bodies of our feline friends allow them to twist as they fall. It’s no wonder then, that researchers at Georgia Tech are studying the way cats flex and turn in the air — so they can apply what they learn in designing robots that can land without sustaining damage. The applications are numerous!

Drone America, an aerospace company, and American Medical Response (AMR), a medical transportation company, have announced a partneship that aims to bring Unmanned Autonomous Systems (UAS) to the EMS industry. By leveraging UAS technologies, AMR’s specialty teams would be able to provide swifter and safer rescue operations in dangerous situations such as disaster response, mountain rescue and swift water rescues.
“We are looking at the various potentials for the use of UAS’s for both the delivery of medical services such as an AED, and as a platform for public safety such as search and rescue operations and communications platforms,” said AMR’s Senior Vice President of Operations Randall Strozyk.
A pre-production model of Drone America’s medical DAx8 UAS was revealed at AMR’s booth during the American Ambulance Association conference in Las Vegas. Recently the AMR DAx8 gave a short flight demonstration inside a North Lake Tahoe Fire Department station for a Channel 8 KOLO News story about drones.
“Drone America’s DAx8 is specifically engineered with emergency services and first responders in mind,” said President and CEO of Drone America Mike Richards.
The first robot and networked tablets are making their way today to an Ebola treatment unit in Liberia, where they will give aid workers their first chance at sharing data about the deadly outbreak.
Debbie Theobald, co-founder and executive director of Cambridge, Massachusetts-based Vecna Cares left on a flight to Monrovia, Liberia Tuesday night, taking the company’s own CliniPaktablets, a robot and the technology needed to set up a local area wireless network.
For doctors and nurses accustomed to scribbling patient notes on pieces of paper in any of the Ebola Treatment Units (ETU) scattered across West Africa, this will be the first time they’ll have access to portable computers that can share information wirelessly. It also gives them an electronic medical record system to track patients and share treatment and disease information with clinicians in other units and researchers in various countries. This also marks the first time a robot will be working in one of the treatment centers.
“I think that this system is critical to fighting the outbreak,” Theobald told Computerworld. “This is the first time they’ll be using digital records at all in any of the ETUs. Everyone has been using paper. If they have had a tablet, all the information they’re capturing is stuck on that tablet because they haven’t been able to data share across tablets.”
Vecna Cares, a healthcare IT company, will also be bringing the medical records system, minus the robot, to ETUs in Lunsar and Makeni, both towns in Sierra Leone. Depending on how well the VGo robot functions and is accepted in Monrovia, others could be sent to Sierra Leone to aid outbreak efforts there.
Researchers are working on technology that could be shipped to West Africa to help fight the Ebola outbreak as soon as a few months from now, while also looking ahead to bigger plans to combat any disease outbreak.
“Absolutely. This is something we can do,” said Robin Murphy, a professor of computer science and engineering at Texas A&M University and director of the Center for Robot-Assisted Search and Rescue said Wednesday. “There are lots of things we found that can go right now … but this will continue to motivate research in human-robotic interactions and how to understand how you design a new technology, how you test a new technology, how you factor in cultural context, how to factor in the targeted environments and how you train people to use them, she said.”
Tech researchers from around the U.S. met with health care and aid workers nearly two weeks ago to discuss what kinds of technology, such as robotics, big data analysis or communications, could help fight the Ebola epidemic. Now plans are in the works to get the technological aid where it’s needed. The Nov. 7 workshop was livestreamed across locations at Worcester Polytechnic University, Texas A&M, the White House Office of Science and Technology Policy and the University of California at Berkeley. During the meetings, aid workers were able to explain to the researchers the obstacles they faced in using certain types of technology.
Nothing can be simply shipped to a treatment center in a foreign country however. All proposals from U.S. companies to send technology to areas hit by the Ebola outbreak must go through the U.S. Agency for International Development (USAID), which administers civilian foreign aid efforts. USAID has put out a call for proposals, and submissions are due by Dec. 1. Murphy said she’s expecting the agency to quickly act on some of the proposals so that some of the technologies can be shipped to West Africa early in the new year.
While researchers are looking at short-term answers for Ebola, they’re also focused on coming up with bigger, more complex systems that can be ready for outbreaks of other deadly diseases.
The Australian Rural Fire Service (RFS) is carrying out trials this fire season with “spy in the sky” unmanned aircraft and drones to evaluate their use to monitor fires for extended periods and to provide early data in the first minutes of arriving on the fire ground.
One test is to likely to take placed in the Wollemi National Park near Singleton, should a major fire operation arise. It will use the Scan Eagle Unmanned Aerial Vehicle (UAV), which can send back both thermal and visual image data and is capable of staying airborne for some 20 hours. Insitu Pacific, the Brisbane operator of the Scan Eagle, believes their use will become almost routine within a year, with a trial contract in place with the Queensland fire and emergency services.
The RFS NSW also has a contract to trial the Octocopter with multiple rotors with a view to it being launched by the first crew to arrive at the scene of a fire to provide information on the extent of the fire front to enable senior crew to determine how fire fighting assets are deployed. Anthony Ferguson, superintendent of aviation co-ordination and planning at RFS NSW, said several projects are looking at their potential usefulness for intelligence gathering around fires.
The malaria drone mission began in December 2013, when UK scientists decided to track a rare strain of the mosquito-borne disease that has surged near Southeast Asian cities. Understanding deforestation may be the key in seeing how this kind of malaria, known as Plasmodium knowlesi, is transmitted.
The mosquitoes that carry Plasmodium knowlesi are forest dwellers. The insects breed in cool pools of water under the forest canopy and sap blood from macaque monkeys that harbor the malaria parasite. Human cases of this kind of malaria didn’t surface in Malaysia until about 10 years ago, says infectious disease specialist Kimberly Fornace of the London School of Hygiene and Tropical Medicine. She is leading the drone study.
As part of a project called MONKEYBAR, the team tracks outbreaks by comparing the drone’s land surveillance with hospital records of malaria cases. Meanwhile, a local wildlife commission has fitted macaques with GPS collars, which let scientists monitor the locations of monkey troops. Together, this information paints a public health map that explains how land development has influenced monkey movements as well as transmission of malaria to humans.
The White House Office of Science and Technology Policy recently organized a symposium of top robotics experts at Worcester Polytechnic Institute to brainstorm how field robots could be used in future Ebola-like pandemics. While the researchers came up with a number of innovative short-term and long-term ideas for how robots could be used to fight Ebola – everything from cleaning and decontaminating rooms to actually administering IVs to humans under medical treatment — there are still a number of important issues to clarify before we hand over the task of fighting Ebola to the robots.
On the surface, of course, handing over the dirty work of cleaning up after an Ebola outbreak to the robots sounds like a no-brainer. Instead of putting humans into harm’s way, why not just send in a robot? Robots can’t develop symptoms from Ebola, they are relatively easy to disinfect (except for their wheels), they dutifully carry out tasks without talking back and they can dispose of hazardous waste efficiently.
Scratch the surface, though, and you can start to see the moral and philosophical questions that arise once robots start doing more than just grunt-level decontamination work. In short, everything changes once robots also become human-like caregivers of Ebola patients rather than just repurposed industrial robots. Even assuming that wise and highly moral technologists have created robots according to something approximating Isaac Asimov’s Three Laws of Robotics, there still exists all kinds of potential for things to go wrong as robots go about trying to observe these laws. Just read any of Asimov’s “Robot” stories (or, better yet, watch the Will Smith movie) to understand how things might go awry.
CRASAR, with funding from the Center for Emergency Informatics, and the TEEX Product Development center held a two day series of workshops on robotics for medical disasters. The major takeaway was that robots do exist that could be immediately repurposed now to protect Ebola health workers but how robots fit into the medical response enterpriseis as important as what the robots can actually do. While most roboticists intuitively know that what will work in the US is not the same as what will work in West Africa, the differences go beyond physical constraints such as level floors, ample power, and reliable wireless communications infrastructure. Less intuitive is that the cultural appropriateness of the technology and the impact on the existing workflows and practices is equally important.
The workshops considered how robots could be used immediately and in future domestic medical responses. Hardened robots (and automation/CPS technologies) do exist that could be immediately repurposed to provide logistical services (e.g., packing and hauling contaminated waste) and reconnaissance (e.g. observing signs of mass graves near a village), less so for clinical applications (e.g., directly working with patients). The participants strongly concurred that a research roadmap is needed to prepare robots that the US can effectively use in future medical disasters.
The success of hardened robots in providing these services depends on ensuring that they are appropriate for the work domain in five ways:
Fit the cultural context. For example, a telepresence robot allowing a certified medical interpreter to talk with the family and talk the patient’s history may overwhelm a non-Western family who has never seen a computer. A less obtrusive telepresence solution may be more practical in that cultural context.
Fit the existing workflow and practices. For the short term, solutions aren’t solutions if they require health workers or medical responders to adopt radically new procedures. They simply can’t handle more things to do or change how they perform their current tasks (which impacts how everyone performs all the other tasks- “simple” changes can have system ramifications). However, small changes that produce at least a tenfold benefit can make a difference.
Can function in the target environment. For example robots in West Africa would have work reliably in field hospitals with canvas floors and narrow doors, muddy dirt roads in the rainy season, with power and wireless communications limitations, etc., while robots in the US would have more pristine conditions. Different groups use different decontamination procedures and chemicals- such as dousing everything with chlorine beach solution (easy and inexpensive) or using more chemically sophisticated decontamination foams used by urban hazardous materials teams.
Are maintainable and sustainable. Health workers and medical responders won’t have the time and skills to repair robots (especially if wearing PPE) and may not have access to consumables such as batteries to enable operations for weeks and months. A problem with the Fukushima response was that many robots were actually prototypes functioning at a Technical Readiness Level of 7 rather than a well-tested Level 9 system.
Are easy to use and be trained on. This is related to fitting into the existing workflow and practices, but deserves special emphasis. The health workers and responders will not have significant amounts of time to learn new tools, as their days are already overloaded and they have little personal time. Robots must be vetted for ease of use. Effective training for medical missions is important and the role of simulation or serious games should not under-estimated.
The sentiment shared by the TAMU participants was that the biggest barrier to near-term use was not the lack of capable robots but rather the lack of requirements that would allow industry to invest in repurposing robots and enable agencies to test and evaluate the robots and develop training.Currently there are no details on the operational envelopment for the robot or operator. There is no clearinghouse of social science data on cultural appropriateness or bioethics or specific missions.
OVERVIEW OF WORKSHOP ACTIVITIES
The first day of the workshop was hosted by CRASAR and held at the National Center for Therapeutic Manufacturing. The day was divided into two portions. One was a simulcast of shared presentations with the other three sites and brainstorming as part of the planning workshops on Safety Robotics for Ebola Workers for the White House OSTP/National Robotic Initiative. The other part, the Texas A&M Workshop on Robotic, Automation and Cyber Physical Systems for MedicalResponse to Disasters, provided additional talks and discussions on general domestic medical response. The Texas A&M talks covered the state of the practice in DoD robots (TARDEC) and casualty evacuation systems (TATRC) that can be repurposed, lessons learned so far in using robots at the Fukushima Daiichi decommissioning (University of Tokyo), and opportunities for community recovery (TAMU Hazards Reduction and Recovery Center). The day culminated with a reception and a thought provoking keynote talk by Andrew Natsios (TAMU Bush School of Government and Public Policy), who served as administrator of USAID from 2001-2006.
The second day, the Infectious Disease Response Workshop, was hosted by Caleb Holt and the TEEX Product Development Center and held at the TEEX Emergency Operations Training Center/Disaster City® complex. The focus was on the practice of medical response (one of TEEX many courses that they teach). A major portion of the day was spent in demonstrations of the current practices in medical response, walking participants through 3 modules of a field hospital (also called an Emergency Treatment Unit or ETU), showing how contaminated waste is stored and overpacked, and how domestic responders, equipment, and ambulances are decontaminated. One demonstration was not a current practice but showed how existing robots might be of use. That demonstration showed the General Dynamics Land Systems MUTT, a robot wagon that acts like a dog and can carry waste, supplies, or one or two litters. A responder guides the robot with a leash rather than a video game controller that is hard to carry and use while wearing personal protective equipment. If the responder stops, the robot stops. If the person backs up, the robot backs up. The second day also featured panels of practitioners, including from the Texas Ebola Task Force and the USMC Chemical Biological Incident Response Force, comparing military and domestic practices
TAMU FINDINGS ON WHAT ROBOTS CAN BE USED FOR
In terms of overall medical disasters, applications appear to fall into one of three broad categories below, regrouping the preliminary list of nine functions discussed in an earlier blog. Each category has a different set of stakeholders and a different operational envelope that the robots would operate in. Clinical applications are possibly what people think of first– how robots can replace what health workers do now—but logistical applications are perhaps the most feasible and practical.
Clinical: Clinical applications are where robots are used in the ETU as a “force multiplier” (another way of saying “reducing manpower”) by taking over some of the activities that health workers do or as adding reliability by coaching or supervising activities. Ignoring for a moment the cultural appropriateness and other adoption issues, robots could enable
Remote health workers to assist other health workers, such as telepresence robots (or just cameras/tablets) coaching or supervising taking off PPE– though the general consensus of our responder base was that having a second person physically helping with decon was more valuable than having someone saying “hey, you touched your face while trying to lift your hood.” Domestic hazmat responders and the USMC Chemical Biological Incident Response Forces use a two personal decontamination process.
Health workers could use robots to interact with patients, reducing the number of times workers have to risk exposure. Robots could provide non-invasive point-of-care such as changing IV bags, though the TAMU participants were more reserved about roboticizing invasive procedures such as starting IV lines.
Remote health workers to interact with family members, such as remote qualified medical interpreters working through telepresence to help with patient intake forms.
Logistical: Logistical applications can take place within the ETU, but the construction, layout, and clutter of ETUs make it hard for mobile robots to move around. Some ETUs have canvas floors over dirt or mostly level manufactured floors, and almost all have raised areas to step over between modules that seem intended to foul wheels. The general thought is that flexible automation and materials handling are more likely to be of benefit within an ETU and that robots would be more useful for outside the ETU. Logistical robots are also interesting in terms of stakeholders. Since they are not performing clinical functions, in theory the robots could be operated by locals (assuming favorable cultural considerations).
Logistical robots could provide
Materials handling. Robots could reduce the number of times humans handle contaminated waste or the number of people needed to carry a litter. The robots could pack and carry materials from the warm zone to the cold zone (e.g., taking out the trash) or carry supplies into the warm zone, saving another cycle of a person having to don and doff PPE.
Decontamination. Robots could spray biocide foam on equipment, though there was several ideas for using gases to rapidly decontaminate ambulances so as to keep them in service.
Delivery and resupply. Unmanned aerial vehicles or boats could drop off small amounts of supplies to villages cut off by the rainy season.
Reconnaissance: Reconnaissance activities take place outside of the ETU. Aerostats or UAVs can provide awareness of long lines or gathering refugees. A more somber recon activity is to fly over villages and look for signs of freshly turned earth indicating graves.
Other: The workshops also touched on preparation for medical response, such as redesigning field hospitals to make it easy to use robots and to add cameras, internet repeaters, etc. The workshops raised the value of automated construction in reducing the non-medical members of the team needed to set up and maintain the ETU.
