I am currently studying Aerospace engineering, and my project work is to create an autonomous underwater vehicle. I have chosen to use buoyancy propulsion as a method of propulsion. Simply by varying the buoyant force you can propel the submarine along. Being an aerospace student my knowledge in electronics is limited, but I do have some understanding.
My project requires me to create an electronic circuit which basically pumps on and off water, with time delay to control the depth. The trouble that I am having is how to control the amount of water that is inside the ballast tank. From water sensors I have used simple logic gates to control but the problem with this I understanding the difference between filling and emptying the tank. Is there any type of circuit or sensor that would be ideal to use to stop this problem?
I want to try and avoid using a microcontroller if possible.
Thanks for your time,
Jack
