Typically, when you use a life preserver, you just throw it to the man overboard and hope for the best. If you suck at throwing, the person being rescued has to swim further to get to the life preserver, and that can put them in danger for longer.
There are a lot of emergency situations that call for the use of rope. Unfortunately, rope pulley systems aren’t the safest way to go sometimes due to external conditions. Like, say, when there are floods or overflowing rivers and people are trapped on one end.
Whistles can come in handy during emergencies and natural disasters. They’re especially useful in catching the attention of rescuers who might not be able to see survivors clearly because of the conditions. Unfortunately, not everyone walks around carrying a whistle in their pocket or wearing one around their neck.
Looking for a lifeguard that won’t get all out of shape like David Hasselhoff? A research lab in Iran is working on one – a robotic lifeguard that can respond instantly to passengers and crew who fall from ships by flying to their rescue and dropping a life preserver to them.
Dogs are pretty good at rescue operations. They can be trained to sniff out survivors in a disaster area and they can traverse some terrain that humans can’t in half the time. However even dogs have problems in some situations.
It’s one thing to have people and dogs helping out in search-and-rescue operations, but it’s really interesting when robots start doing even better than your two- or four-legged friends, thanks to some of their sensors and other features.
It’s been confirmed that there was a nuclear meltdown in Fukushima, Japan. That’s why I think that the Helios IX, which was developed by the Tokyo Institute of Technology, will certainly be able to help out its human friends, since it won’t get sick or die from radiation poisoning.
