Energy Efficient Controller Design For Underwater Gliders Maneuvering

A submarine is defined as “something that functions or operates underwater; specifically: a naval vessel designed to operate underwater.” This definition holds true today but started at the beginning of the Civil War when submarines originally became a popular choice of weaponry. In general, submarine crews were composed of a commander, who steered the boat, and six or more men who used hand cranks to move the boat. Many inventors intended on creating electric motors to move the boat, but they were unable to produce enough torque. Submarines were primarily used in combat because they could travel invisibly. Innovations like submarines did not just change the way people fought wars–they also changed the way people lived.

Around the mouth of the octopus are eight arms. The eight arms allow the octopus to move, crawl, and swim around in its habitat. Octopuses crawl slowly, walking on its arms to move through the water headfirst with the arms trailing behind. When necessary, octopuses can move fast using their arms to propel it through the water similar to jet propulsion. The suckers found

A submarine can controls its buoyancy force,which is a force that acts opposite to gravity, and pulls down the ship. Submarine can control this, so it can choose to sink or float. When the tanks in the submarine are

Submersibles can carry as many as 1,500 pounds of research tools to the ocean to research. Submarines could let marine biologists to stay underwater for six to 10 hours for observing and finding new object. These are only few important tool that marine biologist uses to observe and

Providing for homeland security in the United States requires protection from a diverse set of threats. One prominent avenue of attack is via maritime routes, yet the nature of the coastal marine space makes it extremely difficult to detect and intercept smuggling vessels. Many sensing technologies exist for detection of seacraft, but there are few options for deployment of these sensors. Currently, such sensors are deployed on various manned vessels, tethered buoys, and aircraft. Development and testing of purpose built anti-submarine systems such as DARPA’s ASW Continuous Trail Unmanned Vessel (ACTUV) (more colorfully known as the “ghost hunter”), is underway but suffers from high cost.

COTSbot, which operates autonomously, recently performed well on trial test and its creators plan to deploy it in December. Until then, the robot needs to be tested on the reef.

As larvae, these animals use cilia to move themselves through the water. Most of their travels however are dictated by the ocean currents. They literally “go with the flow.” When they do move on their own, it is usually to be near the surface of the water. They do this by propelling themselves through the water. The base of the bells is lined with muscles that contract rhythmically creating a jetlike

Submarines require a great deal of energy in order to propel itself while out at sea, energy which is generally provided by a reactor. The

The purpose of this lab is to show how the quantity of wings effects the height a 2 oz. bottle rocket launches into the air. The wings have a vital effect on the flight of the rocket. The fins keep the rocket stabilized and going in the right direction. The way that the fins do this is the same way that the feathers on an arrow keep it flying straight. The increased drag on the back end of the fuselage of the rocket, keeps the back end in the back.

In the study the wind speed was estimated by interpolation between widely spaced measuring points. Even better results might be achieved if GPS data was more tightly coupled to actual wind speed. Another way to improve the study would be more detailed description of the very fine adjustments of orientation to the wind that are used to optimise the flight. Could this be done by flying a drone alongside an albatross to record precise wind speed and capture high definition visual data? This would augment the understanding of dynamic soaring to survival value with insight to the causal factors that control the

SilverHook Powerboats, maker of some of the world’s fastest watercrafts wanted to use this sensor data collected from racing boats to improve the decision-making abilities and safety of racers and to enhance the fan experience. The challenge for racers and observers was alike- keeping track of

I take this opportunity to express my sincere thanks and deep gratitude to all those people who extended their whole hearted co-operation and have helped me in completing this project successfully.

The interest and research works based on autonomous underwater vehicle has increased a lot in recent years. Because of the mass applications of AUVs for security, maintenance as well as under water research works it is really

I would not forget to remember Prof. Suresh Pattanayak, Prof. Rupesh Kr. Tiwari and all faculty members for their unlisted encouragement and more over for their timely support and guidance till the completion of our project work. I heartily thank our internal project guide, Dr.R.S.Mohan, Dean , Department of Management, for his guidance and suggestions during this project work. I am extremely thankful to all those persons who have positively helped me and customers who respond my questionnaire, around whom the whole project cycle revolves.
