Slideshow: Nautical Robots Go With the Flow
4/25/2013

The Serpent remotely operated vehicle (ROV) from Seaview Systems is designed for exploring very small-diameter pipelines. It can investigate conduits as small as 9 inches (23 cm) in diameter, and fit around bends with a radius as narrow as 27 inches (68.5 cm). Measuring 9 inch x 9 inch x 57 inch (23 cm x 23 cm x 145 cm) and weighing 70 lb (32 kg), the Serpent runs on two 300W brushless DC motors that give it a total forward thrust of 18 lb (8 kg). With a 0.5 inch (1.3 cm) diameter fiber-optic tether, it can explore as far as 6,000 ft (1,830 m) down a pipe or tunnel. A 360-degree pan/orbit/zoom color camera and two color cameras are included, along with two 70W high-intensity LEDs. The robot also has heading, pitch and roll, and depth sensors, as well as sonar. A fiber-optic telemetry system provides up to three video channels, four RS232 channels, and two RS485 channels.   (Source: Seaview Systems)

Its an excellent slide show agreed and there will be no doubts in saying that Robotics are becomming more and more common these days and using robotics underwater is a very wise approach because it can be difficult and dangerous for a human to go underwater and explore.

Secondly according to the research most of the planets consist of water and water so using underwater robotics will help to investigate a lot in them as well.

But this is a rule of life that every technology has its pros and cons.One of the advantage is mentioned above only that majority of the planets consist of water and it can be helpful in doing research.Secondly it can be initially tested in pools.However the disadvantage is this that it can leak ,sink because no matter how accurately it has been created  its just an electronic development only.Secondly there are very less means of wireless communication and then because its an electronic device its every part is either a device and some devices stop working in water so it can  malfuunction as well

I agree.  Does God's design have some unique abilities or benefits that science just can't duplicate or improve on.

Sometimes it's interesting how no matter how much we try to make things better, it's the original that performs just fine.  In some cases, I don't know if there can  be improvements, in others, I think it's the fact that the original can do 95% of the job and the other 5% aren't really missed.

I too have had to spend some time in a few submarines.  And I agree it must be rough.  I always wondered if there wasn't a height limit on those serving in submarines.

Interesting thought.  How many of us think about what it would be like to design for robots underwater.  We are so used to thinking about designing in air.  Quite a challenge to design for underwater.  The drag, the water dynamics.  All of that could be quite a challenge.  We'd have to all go back to some of those fluid dynamics equations.  Great thought.

You bring to light several of the challenges designing for underwater.  Thanks for sharing.

Nice slideshow. A very interesting range of design styles and the thought that went into them.  All the sensor payloads are a science unto themselves.  One of the most interesting facts was that one of them had a magnetically coupled powertrain; great way to keep leaks from occurring under propulsion.

Great slideshow, Ann. It's interesting to see the diversity and technology range of these robots, even while they share some features in common.

Some of our culture's most enduring robots appeared in the 80s. The Aliens series produced another evil android, and we saw light robot fare in the form of Short Circuit. Two of the great robots of all time also showed up: The Terminator and RoboCop.
A soundproofing invention called Acoustiblok recently won a television challenge to silence an air horn with only a fraction of an inch of polymer material.
Robots came into their own in the 1970s. Gone were the low-budget black-and-white B movies. Now robots roamed in full-color feature films with A-list actors.
Major global metropolitan areas are implementing a vast number of technology, energy, transportation, and Internet projects to make the metropolis a friendlier, greener, safer, and more sustainable place to be.
Here’s a look at robots depicted in movies and on TV during the 1950s and 1960s. We tried to collect the classics here, omitting the scores of forgettable B movies such as Santa Claus Conquers the Martians and Dr. Goldfoot and the Bikini Machine. Stay tuned for slideshows of robot stars from later decades.
