Post all your ROV pictures or ROV's in progress! I personally am still in the planning stage for my ROV but i'll try to post pictures as I go of it.

I'm looking to set up a homemade ROV (probably using the SeaPerch or Seafox designs) and was wondering if anyone had successfully mounted a camera onto either of these systems. If so, I'd really appreciate it if you could shoot me a message. Thanks!

1) I plan to do a ROV so i gathered some information, But i need more help how to get the ROV from deep water to surface? 2) I have to take pictures from underwater and i have to do some image processing through Matlab so suggest me some best underwater cameras? 3) Please explain me about UROV thrusters?
Question by athuv | last reply
I am building an ROV and I need to know whether this control board will work. I planed on Running 1 Cat5 and 1 set of speaker wires to control and run systems on-board. When I flip a switch on the control panel, a 3v signal is sent down the Cat5 wire to the base of a transistor, which opens the flow of power between the Emitter and collector. My main question is, does a transistor work as a switch? Example. A signal enters the Base and opens the other two connections. Is this right? Oh, and the other two pictures are what i plan for it to look like. I am building it using the motors from one project (posted recently) , the frame another, and my own control. I will post an instructable as soon as it is done.

I would like to know how easy it is to cut off the end of the cable and splice in additional cable between the camera and the connector for the PC. I also am curious how long I can make the cable without the loss of functionality - I would like 50 feet if I can. Thanks PaleoDan

I believe that nature in itself has the solution for all our problems . I believe that a combination of mechanical engineering and marine biology (marine comparative bio-mechanics) can provide a new scope of development . I have always been fascinated and intrigued by marine animals which have survived billions of years and great changes of the Earth . ( eg . nautilus) [http://en.wikipedia.org/wiki/Nautilus ] . Its my understanding that this cephalopod has the most effective and energy conversant method of locomotion. It uses water jet propulsion for motion and uses the air cavities inside its shell for buoyancy . These mechanisms of locomotion can be studied and modified for creation of low-speed , high-efficiency underwater locomotives . The Nautilus v.1 is a fusion of both biomechanics and state of the art electronics. It uses the habitual and operational features of the living fossil nautilus. The living nautilus is the sole inspiration reason for this underwater utility simply because of its magnificence. It has survived for millions of years in the open oceans which is a remarkable feat in itself but surprisingly it makes a daily trip of 150-200m from the ocean bottom to the surface nocturnally for feeding. Even though Nautilus v.1 uses many of the systems used by underwater rovs , it stands a class apart by achieving partial autonomy . The Nautilus v.1 is far superior from its rivals such as openrov, sea perch, etc. because of its low power consumption and longevity. It attains this by excluding power consuming components like propellers. Its operation is completely on the basis of neutral buoyancy attained by productions of gas bubbles by simple water electrolysis. The gas bubbles are collected in different gas chambers for operation at different water levels. The salinity of sea water facilitates water electrolysis and more gas can be produced with less currents. Graphite electrodes are used to prevent electrode corrosion. The electronics part is still under discussions for an optimum control unit. This will act as the base for addition of sensors and locomotive systems. Currently the main two platforms under work are the beaglebone black and the android versions. Both have their own advantages and disadvantages. Beaglebone would be optimum for component level additions, such as sensors can be added on, whereas in the case of an android system such as a smartphone, most of the sensors are inbuilt and their raw data can be attained.

I am participating ( with other students ) in a highschool level underwater rov competition, i would LIKE to use arduino to control the robot. BUT ive never done something like this before what id like to know is besides the Arduino board ( not sure if Uno would work or if Mega would be necessary ) what kind of compnents would be necassary Like would the arduino be controlling the motors directly or would it control something to turn on/off the motors? as the motors run on higher voltages then the arduino does and what would the control side of it be like? i would LIKE to have a basic joystick (2 axis, nothing fancy) and a few buttons but would that require a specific shield or something more complex?

I am in the process of building a SeaPerch ROV, and I want to add a few sensors with an Arduino. I have the other ones figured out, but I can't figure out what I could use for a depth sensor. I've thought about using a pressure sensor and calibrating it to give me a rough estimate of how deep it is, but I don't think that'll work too well. So if someone has some ideas for what I could do for this, that would be quite helpful. Thanks.
Question by mbudde | last reply
I am working on an underwater ROV for a competition and have been considering using Arduino to control it. However. I have not actually ever used Arduino and therefore have no knowledge of the subject. So my question is this, what would the basic components be for controlling the ROV be? It would have to be able to control several (4-ish) medium sized motors as well as 2-3 small motors and i would LIKE to have either a joystick and a few buttons on the controlling side. I can imagine ALL the power would be unable to be run through the Arduino system so would it be that there would be some kind of second component for say each motor to control power flow? Also the motors are "double throw switch" motors so there would not need to be any kind or" throttle "
Question by shabaki
This is just an idle thought, but I was reading a couple of ROV builds, and the one thing they all have in common is a tether - it's a fact of the world that very little in the way of radio signal can penetrate water. So... Could you send control signals to an ROV via sound or ultrasound? Could beeps and clicks carry enough data, far enough, and clearly enough, to control an ROV? Even more fun, how much data could come back? Sensor readings? Images? Just throwing it out there for you to toy with, but it would be fun to have genuinely-remote control for this class of robot.

The power is coming from a battery, and so is DC and has nothing built in to vary it. For example, what potentiometers or the like could reliably handle it?
Question by electrick | last reply
Hi, is there anyway to attach a camera to a ROV, robot, RC car/plane? I was thinking maybe using like a radio transmitter to transmit the signal or whatever. Also accepting non-radio ideas. Oh, and the smaller the better, and long antennas=not an option. (Maybe a dish, but no antenna, atleast not the long kind).

I am making an underwater ROV, like a remote controlled submarine, and I am looking for a way to control it. All of the commands are set up to run off of serial commands going to the on board arduino. This is what I would like to know: Is there an easy way to send custom serial data over a computers USB port, controlled by some sort of virtual controller
Question by ConnorFD | last reply
I'm building an ROV for the MATE ROV competition with a high school team this year. For this year's competition, we've decided to control our bot via an Arduino Mega, and we're using PWM to potentiate the thrusters. As the person designated to electrical, I fortuitously have no idea how to set up an intermediate step from the Arduino to our thrusters. I've looked into H-Bridges with both Relays and Transistors, and defaulted to the transistor. How would I choose what transistor to use though? I've tried several (all BJTs) and they're giving me nothing but problems. Should I switch to a FET? Should I use a P type and an N type, or only one? What specs should I purchase them with? Do I ask too many questions? Help! (I'm trying to control a 12V 6A motor with a 5V Pwm signal. Thanks!)
Question by unununium | last reply
I am building an ROV that uses four thrusters, each can draw up to a maximum of 3-5 amps (motor says 3, website says 5 here). However, I will need to step up the voltage and I cant find anything that provides more than 10A continuous (currently using this but open to a higher amp option), so how can I limit the current the thrusters use in order to make sure that I dont blow out the DC-DC converter?
