AUV Lipo Battery capacity

You don't gave all information that are needed for such calculations. However, the technical details of the Thrusters give a peak consumption of 350 Watts each. So you have 6 of them, makes overall 2....

Why the bldc motor not able to move my water boat?

It sounds to me like you've got cavitation. Basically, the blades are turning so fast that the water around the blades boils. Boiling can happen at normal pressure and high temperature, like on a ...

RC transmitter/receiver for underwater robot

Is the robot going to have an over-the-water antenna? If not, then electro-magnetic communication is a no-chance under-water, if the water is salty (seas, oceans) or if the distances are long. The ...

How to localize an acoustic source underwater with a hydrophone array

The simplest answer would be to use the phase difference to calculate the direction -- rotate your array until all sensors get the same phase, and you've found the direction to the source (or do some ...

how to get an 8 hour autonomy for an underwater robot?

Lithium Polymer batteries are, in general, the best you're going to get as far as either energy per weight or energy per volume. Going to a different brand may gain your 10% more capacity per volume, ...

Underwater navigation without the use of acoustic sensors

Usually, most underwater robots are running on just inertial navigation and surfacing occasionally. This tends to work better than one would expect and is what most large scale deployments end up ...

how to get an 8 hour autonomy for an underwater robot?

In underwater autonomous vehicles there are basically two solutions to increasing long term autonomy. The first, better power generation, (which has already been mentioned) won't really work in your ...

Why to seal a motor shaft, or the whole motor, for underwater ROV?

Brushed motors are functionally waterproof not by design but by principle (brushes sending power to a stator, spins the motor) and will run under water, albeit inefficiently. Most brushed motors have ...

Area coverage of autonomous underwater robot

If you can't localize, you can't do anything that requires localizing. If you can't use wheel encoders accurately enough to do a rectangular fill (parallel lines) then, by the same reasoning, you can'...
