On i2c you can have as many slaves as you want connected to one master (Arduino in your case). That is because every i2c device has it unique serial number and while you are programming master there is a sequence when every device should present itself (one at the time) and master save it (in your c...

What programming do you need? For aplication on a computer or embendded systems? There is not much difference. Only communication can be problem on both (becouse of linking on computer and building protocoll on embendded system). So I suggest you to choose a bit powerfuul tools (not asm). If you are...

You can measure current that flows throu DC motor. If it grab object to much, current rise. So you can use two buttons to close and to open gripper. I think that without any logic, you can not control underwater gripper. If the gripper is on shore, you can use end-switches and some relays. With Ardu...

Generator make VAC. Inverter invert VAC into VDC. VDC is use on ROV but he can still use VAC for computer (if he does).

Use steel pipe. You'd never watch Mythbusters?

I think they will do it. If the motor doesn't produce enough power, you shall raise the voltage to 6V or 9V.

If you insulate it very well will be fine. If you need 7A be shure that you got source (batterie) that can provide at least 10A. In that way you can prevent overheating.

You can make your own DC-DC converter from 24V to 20V or lower. It's not so hard. You can use LM2577. With good cooller it can manage up to 5A. It has 80-90% usefull efficiency.

What about silicone mass?

That problem is easy to solve. Use one relay and switch. Use NC contacts on relay for power source on both relays.
