Senior project, need help planning and designing a underwater ROV/AUV with gps for freshwater rivers/ponds..?

For my high school senior project in my three year robotics/pre-engineering project my partner and I are planning to design and build a working underwater ROV / AUV with cameras and gps. I want to be able to control it by a remote and the cameras but also gps control it to go up and down a pond. I am aware that GPS signals will not penetrate the water. Im trying to keep it low cost and small, any help is greatly appreciated.

if i cant make it autonomous, id like to make it remote controlled by me on shore by looking through the cameras on it, i do not want it tethered to shore, i need help...

thanks...

It will certainly need a cable to achieve this as the other methods of remote control are unsuitable. There are acoustic modems for underwater, but no good in a pond (echos are fierce) and you did say low cost. I assume you will have an on-board battery for propulsion, though this is limited in power. Use the biggest battery you can, probably a 12V system is easier to match up with the parts you will find.

Among the simpler methods is to use a 27MHz radio control system as used with other models, with the transmitter connected to the cable and the receiver connected at the other end. A balun is used for this at each end - basically a transformer that works at 27 MHz and matches these devices to the cable impedance. This is not likely to work on very long cables, but you did say a pond. Normally a coaxial cable like RG58 would do, but twisted pair is a possibility.. There are problems with the PVC sheath of most cables as they are not impervious to water. If you can find a cable with neoprene or polyurethane outer sheath it will be better and last longer. Cable used for submersible pumps is a possibility.

Making it autonomous is a high demand, involving navigation using sensors and control of trim, depth and position, as well as mapping and obstacles. It needs considerable computer power and complexity, and would be something you probably have to develop yourself.

If you wish to read signals and watch TV this means additional wires in the cable. Expect that a TV picture becomes considerably degraded with a cable longer than around 30m, but an equaliser and amplifier may be used to correct this. Expect that to work up to 100m.

Finding a suitable cable at a reasonable cost is a major issue. It is unlikely to be feasible for more than around 100m. Flexibility, cost, drag, waterproofing, weight, suitable wires. If you have a buoy or raft towed by the ROV it could have GPS and other radio links back to the shore and more batteries. However a battery operated ROV is likely to run out of "puff" trying to tow that. It would allow a shorter cable, maybe 10-20m is enough. One possibility is a WIFI to RS232 modem/adaptor on the buoy. If there is a microprocessor in the ROV it can use RS232 or related RS422 links over long wires without much trouble.

It may be better to go for a land based machine like a crawler for bomb disposal first. It has less costly problems to solve. The underwater aspect means you need skills in fitting and turning almost certainly, seals, "O" rings, magnetic shaft couplings.

Look up the various key words I have used to find solutions. Also search for building ROVs and you will find various ideas about the many issues.
