Iím planning on building a submarine for my ME robot class thatís about to start. I want to control its depth by opening a valve and allowing water to enter and air to escape. At certain depths I want to shut the valve off and make the sub neutrally buoyant thus not sinking. I imagine the pressures inside the sub and the water outside must be the same for it not to sink. How/what instruments will allow me to measure the pressure inside the sub and outside? Some kind of sensor? How do real subs do these? I can't touch it after I turn it on, it has to operate by itself. I know how to program in basic so I plan on using the small circuit boards the class provides. Iím sure there is also some equation like Pinside + weight = PoutsideÖ any help there? Thanks for your time
