It looks like from the internet news that it has been a busy day in New Zealand with two robots and a third being prepped. My hat’s off to the Kiwis for aggressively pursuing this technology. I know of only one other case- the Midas Gold Mine Nevada collapse- where more than one robot was deployed. And that was one at a time (the first robot from nearby Fallon NAS was too big and heavy for that type of void, so CRASAR was called in and we brought in an iRobot packbot and Inuktun/ASR Extreme VGTV from the US Navy SPAWAR small robot pool. The packbot was too big so we used the Extreme, so only 2 robots were used.). It sounds like that more than 1 robot is, or was, active at one time at Pike River, so that’s a record.

The Mine Safety and Health Administration, under the direction of technology director Dr. Jeff Kravitz, is bringing the V2 (the Remotec Wolverine variant that is to the best of my knowledge the only mine permissible robot in the world) to New Zealand. I am currently waiting at LAX for them to arrive, as I’ve been invited to join their team. I can’t wait to “meet” the other robots (and responders). Jeff is a real unsung hero of rescue robotics, he has been involved with the most underground mine rescue robot deployments in the world. We’ve worked together since 2006, you can see him in this video about the rescue robot at the Crandall Canyon Utah mine disaster, and we are co-authors of a paper summarizing underground mine rescue robot technology and the nine deployments as of 2009.

I’m sure I speak for everyone that we’d be thrilled to arrive in New Zealand to discover that the 29 miners had been found alive and had been extricated; they remain in our prayers.

A sad day with the robot failing in New Zealand and no resolution on the missing miners. I got asked many times today by the NZ media about the ways a bomb squad robot could fail or fail being used as an underground mine rescue robot. Mobile robot technology is still primitive (most robots are not as sophisticated as they could be due to economic barriers) plus search and rescue is one of the hardest, if not THE hardest, domain.

I am afraid that we may be losing sight of while there are many ways for a robot to fail, a single success could save 29 lives.  And if not this time, we learn for the next- because there will always be a next time.

Our deepest, best wishes for the miners and their families and also the responders who are pushing the envelope to try to find the missing.

Peter Griffin of the Science Media Centre in New Zealand has just given us a heads up that rescuers will be attempting to deploy a robot in the search for the 29 missing miners from the Pike River coal mine explosion. Our prayers are with the miners, their families, and the responders and we hope for a happy ending like at Chile.

The video above is from the robot at the Crandall Canyon Utah coal mine collapse and pictures are in the media gallery. A paper summarizing a study CRASAR did for the US Mine Safety and Health Administration for all 3 types of mine robot rescue is here and give the prior deployments, advantages and limitations of robots for each. The US Mine Safety and Health Administration and its lead scientist, Dr. Jeffrey Kravitz, is the world leader in underground mine rescue deployments and CRASAR is proud to have assisted with two mine rescues. To date, there has been no known “live saves” of miners with a robot but we’re hoping this is a first.

What is it with disasters? They’re coming fast and furious. Here’s the 411 on robots at the China quake.

The Qinghai quake is the latest of the series of tragedies. Prof. Bin Li at the Shenyang Institute of Automation and an active member of the IEEE Technical Committee on Safety Security Rescue Robots, contacted the Chinese national earthquake response service this morning. It doesn’t look like ground robots are appropriate– the structures are mostly small and constructed from brick and mud. That type of construction is problematic– the brick and mud turns to a liquidized dust, acting like water to fill all the voids and displaces air. Even if there are voids, the suspended dust causes respiratory distress. Eric Rasmussen InSTEDD has many tales to tell of the similar Turkey earthquake.

China, by the way, does have at least one rescue robot. Bin tells me it was deployed to the mine collapse but could not be used because it wasn’t waterproof. (A gentle aside to manufacturers: d’uh!)

Aerial vehicles might be helpful for tactical operations and I can’t help thinking that an unmanned marine vehicle with an acoustic camera capable of penetrating turbid waters could provide more information about that crack in the big dam…

Bin was a participant in the NSF-JST-NIST workshop at Disaster City at the first of the month and we look forward to working with him and his group. In the meantime.. I’m speaking tomorrow at AUVSI day at the Capitol– I hope that in the future we can do more than offer our prayers.
