Many robots designed to operate on or in water are destined to serve in military, naval, and homeland security capacities. Others are aimed at scientific exploration and data gathering, such as monitoring marine ecosystems and gathering data about water quality. Some of the plainer ones are remotely operated vehicles (ROVs), underwater unmanned vehicles (UUVs), or autonomous underwater vehicles (AUVs): the naval versions of their unmanned ground vehicle (UGV) and unmanned aerial vehicle (UAV) counterparts. Others look like fish, jellyfish, or submarines.
Whether they navigate the salty seas or fresh water lakes, rivers, or oceans, many models can do a number of different types of tasks, depending on their payloads. Robots made to work in water are usually designed to be either remote-controlled or autonomous, and some can even switch from one mode to another.

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)
Nice slideshow Ann. Quite a wide range of differences in structure. It would be interesting to know whether the robots designed to look like sea creatures are intrinsically superior to the clunky looking water bots.
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
Clean diesel continues to be the fuel of choice for transportation authorities in major U S cities, in spite of competitive options aimed at reducing emissions, according to a nonprofit agency that represents diesel engine and equipment manufacturers.
A panel at this year's Consumer Electronics Show in Las Vegas discussing upcoming FAA regulations for non-military drones brought out many of the issues that concern both industry and federal regulators.
