Selection Rejection

Selection/Rejection/Intention Report



I have developed three different solutions for the controls for the underwater ROV. In this report I have each solution with their pros and cons. There is also a picture for each and at the end I used this report to help me choose one solution to be the controller.

My first solution is a slanted box with eight different toggle switches, one for each of the different functions. I feel that although it is very straightforward and easy to use it is not as comfortable as my other solutions and with that many buttons it may be hard to reach all of them and even though it is easy to understand which switch is which when under the pressure of the competition it is possible to accidentally use the wrong one. This solution would be easy to create because it only has about eight toggle switches which are easy to install. It would be a good idea to use this because there would be less of a chance of it not working before or during the competition.

My second solution is similar to the first. It is the same box structure and still has two toggle switches it also has a joystick for the movements of the vehicle. The joystick would make it marginally more comfortable, easier and less confusing because there are less buttons. It is still easy to create and by putting in the same amount of work as the first solution I could get a better controller.

My third solution is different from the other two solutions in its size and shape. It would use the shell of an xbox controller and the two analog joysticks. Both of my teammates are experienced in using this controller and all of the controls are simple and easy to understand. This would most definitely be the final solution except for the fact that it is must harder to create than the other two solutions. When the time comes for the competition I would rather have a controller that I am confident in my ability to create and be able to fix at the last minute if something goes wrong than one that is harder to understand and put together.

I have concluded that my final solution will be a mix of two of my alternative solutions. I will have two controllers, one for the steering, and one for the arm, power, lights and cameras. The one for the steering will be the xbox controller because my teammates and I have all used this controller before and are familiar with it but because there wasn’t an easy way to have all of the controls on just that controller I decided to make the second one which was the first alternative solution. The only thing that would be different with my first alternative solution would be that instead of having eight toggle switches i would only have three, which would also get rid of the confusion of all of the toggle switches. This was perfect because it is best for just the toggle switches and not the steering. The two controllers would be used by two team members. one will be steering the ROV and the other will using the other to open and close the arm when necessary

Research- Controllers

Controllers
used to operate something. There are many different kinds that all vary in shape and sizeA controller is an input device depending on the task it is designed to do. My project is specifically to design a controller that is both efficient in controlling the ROV and also efficient for the user.
One type of controller is the joypad which is simply a controller with buttons and smaller joysticks on it. they can range in size and shape. The newer ones are easier to handle and more comfortable for the user. Another is the paddle which is a very primitive controller that is held with one hand and has one and sometimes two buttons. The joystick is a stick that can be moved in different directions to simulate the motion of the object you are controlling and usually has one or more buttons on it or to the side. It is very efficient in its ability to control many things with very few controls. It can sometimes be confusing because it can be so complicated but it is very useful to those that know how to use it. The keyboard, mouse, and mousepad are typically used for games and other functions that are done through the computer. very useful when working with a lot of different outputs.

Alternative Solution 3

Brainstorming

1. This controller would be two seperate ones so that maybe two team members could work on it at the same time. One could conrtol the arm and the other the rov or on the arm and the up and down movements and the other all the other directions.
2. This controller would be similar to the xbox controller or the xbox controller. I would use the shell of the controller so that it is already comfortable for the user. there wold be two joysticks to control the movements and the opening and closing of the arm.
3. My third option nis to use a computer joystick. this would be very easy to use since it was made for the user. it would be very coplicated though because there is a lot of work that goes into creating a specialized controller and modifying it.
4. the next is probably the most straightforward and simple. it is not very user friendly in the fact that it is not molded to our hands or comfortable. it is user friendly though in the fact that it is so simple to use, all the controls are right in front of you and there should be no questions on how to use it.
5. the fifth idea it also pretty straightforward but may be a little more simple. because you are substituting most of the directional buttons for a joystick it is less easy to get the buttons confused.
6. the last idea is replacing all of the buttons with two joysticks. this could be hard because it doesnt make much sense to replace the opening and closing of the arm with a left and a right movement.
   

Below are all of the sketches done over the summer of what our ROV could potentially look like with different ideas for body shape, propulsion and the arm.

Alternative Solution 2

Alternative Solution 1

Background

Background Information

Underwater remotely operated vehicles are most commonly used to do what humans are unable to do underwater. They are unoccupied, highly maneuverable, and are controlled by someone aboard a surface vessel. They are attached to the vessel by a tether and are commonly equipped with two cameras, robotic arms, and lights to gather information (Remotely Operated Vehicle).

Underwater ROVs can range in size from that of a bread box to the size of a small truck. Smaller ROVs such as micro and mini (aka eyeball) are used as diver alternatives. They are given the name eyeball to differentiate them from other ROVs that would be able to perform intervention tasks. General ROVs typically have less than 5 horsepower of propulsion and generally have one three fingered hand to accomplish small tasks. They usually don’t go deeper than 1000m (Remotely Operated Vehicle).

Light workclass and high workclass ROVs are each able to carry some manipulators. They cannot work below 2000m and 3500m. the last class of ROVs is the Trenching/Burial. They have more than 200 horsepower of propulsion and have the ability to carry a cable laying sled and work at depths up to 6000m (Remotely Operated Vehicle) .

Although there are different classifications for underwater ROVs all are made for different purposes. Some ROVs are kept aboard the ship to be used in emergency. For instance if the ship becomes entangled or otherwise incapacitated the ROV can be sent to investigate so the crew knows how to react. Another use for ROVs is science objectives and support exploration. When the water is too dangerous for a submersible or for divers the ROV can be sent to explore and collect data. It can also be used to confirm that a dive site is safe before a sub is deployed, limiting risk to the expensive subs and their pilots (Remotely Operated Vehicle).

In all no matter what classification an underwater ROV is they are designed to perform specific tasks that the creator wants it to do, from investigating dive sites before more complex and expensive submersibles are deployed or to collect small amounts of data from a specific area (Remotely Operated Vehicle).

There are many different types of remote controls, including radio, ultrasonic, laser, mechanical, and infrared controls. When controlling vehicles like cars, boats and planes, radio controls are most often used. Ultrasonic control is used in telephone answering machines and in some television sets. Guided weapons such as bombs and missiles generally use laser control. Mechanical control is used in handling radioactive materials and Infrared control uses a photodetector in most televisions, VCR's, stereos, and car audio systems.

Testing

Expectations

This controller must operate all of the motors and open and close the arm. It must be comfortable for my team to use. It must be tested in the Monmouth University pool no later than two weeks before the MATEs competition in Falmouth, MA.

Procedures

1. Check to make sure each function of the ROV works out of water in the Tech Lab (Left motor, Right motor, Vertical motor, Open/close of arm)
2. Put ROV into water and make sure all functions work, make sure nothing is short circutted (Tech Lab)
3. Go to Monmouth University Pool and do all out of water tests again (Left motor, Right motor, Vertical motor, Open/close of arm)
4. Put ROV into pool
5. Move ROV around pool
6. Perform tasks set by MATEs competition
7. Take notes on how the controller preforms, how it feels, and how easy it is to understand and use. Comment on ways it did not meet expectations and how to fix these problems.
8. Make sure each teammate and the three team members from the other team test controller.
