Re: Mapping the ocean floor

Considering the amount of time it took just to map the land...

Re: Underwater or Above water??

There is something to remember or consider. 1. Weight. 2. Mass. 3 Volume. It can be very easy to get these 3 things mixed up / confused with. When you build seabed tractors. If they are too heavy (Weight) They are damn hard to launch and recover, in choppy water. Mass can help with traction, moving ...

Re: Underwater or Above water??

Ummm! compressed air will add positive lift... <><

Unless the volume of the air is quite small :idea:

Most seabed machines used oil to fill open voids. (Any oil or non-conductive liquid.)

Re: TigerShark ROV for exploring Puget Sound

Your Rov is great.

Like the idea of it being part of your engineering studies and for it to be expanded to.

Keep going your doing great. Also if you have any video of your dives please lets see any of them. (You could also add a music track, for fun...or ping ping noise..)

Re: Underwater or Above water??

Your Rov looks ok and your basic idea is ok to. So can I ask... How deep do you think you can go with this (feet, metres...miles..!) Just asking because the depth can alter my advice. In theory a tracked rov can go all the way to the bottom of the ocean. I have had them down around 1100 metres.(3600...

Re: Underwater or Above water??

Almost any battery will produce some 'gas' Which can cause problems. 1 Fire! 2 Explosion! 3 Compression and then explosion.. In the design build in a valve to bleed-off the gas. (Think of a valve on a hot water radiator ) I used to have to bleed off a battery pack on an Rov. It used a hydraulic pipe...
