Ann, such real time tracing technologies will help to identify the moving pattern of shark. Moreover I think a small modification in the system may help to extend the study to other underwater specious too.  but am not clear how long (range) the signals can be transmitted through under water, which can disintegrate on long distance under the acoustics  conditions.

Social sharks

Ann, if this is like a social network for sharks, the next step is letting them communicate with each other.  With all the advances in robotics that should be something that is being researched.  Then, Facebook could sell ads to them.

Nice article, Ann. Compared with the robots you've been covering, this one is a bit less exotic. But still cool.

It would be nice if OTIS could track some of the great whites that spotted on the East Coast this past summer. It's certainly better than a guy with binoculars standing in a shark tower.

Chuck, as you probably remember, Elizabeth did a story about great white tracking in the Pacific off San Francisco. If it works, it could be helpful on the East Coast. That is, if they could tag every great white.

That is funny, naperlou, but seriously, the implications of turning these tags into a network is a great idea.  If the connections between enough sea creatures were initiated, a real-time 3D view of the enviromment and creature interaction could be invaluable for understanding the interrelationships of sea dwelling creatures, and their migration patterns.  This could also give early warning to adverse environmental conditions.

Good memory, Rob! Yes, this does work, and in the future this will really give marine biologists a weapon to keep track of a number of sea creatures, sharks, of course, among them. But imagine the possibilities for tracking other types of fish and observing migration paths, depletion of fish in overfished areas and other patterns of behavior. Long-term these types of robots could prove to be valuable ecological and even economical tools. There also could be other applications for a wireless network in the sea.

akwaman, I was just being facetious, and I fully agree with you.  It would be really useful.

I agree, Elizabeth, there are tons of applications for this type of sea tracking. It would be interesting if there were a widespread effort to tag great whites. That would be the only way to help avoid beach attacks.

Hi Rob, I agree. I wonder if this robot can track the Box Jellyfish which has been a plague to Australian Beach goers for years? Also, does the torpedoe shape of the robot seem threatening among onlookers, especially the Coast Guard, while it tracks Sand Tiger Sharks? As always, very nice article Ann!

At Medical Design & Manufacturing Midwest, Joe Wascow told Design News how Optimal Design prototyped a machine that captures the wing-beat of a duck.
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
