I’m working on a university project where I use the BlueROV for performing various tasks on objects in a small pool of water.
What I’m looking for, is a way of sensing the distance to objects in front of the ROV. The distance measure should be reliable in the range of about 0-3 meters. The water depth is only about 1 meters. I have attached a sketch of the pool-environment.
As my budget is rather limited, I’m looking for a low-cost solution in the range of $100-$200.
I would like the sensor to be rather easy to interface with a small computer like the Raspberry Pi or Arduino.
After a small research, the best solution I could come up with is to use the Maxbotixs water resistant sonar, and then waterproofing it using RTV.
I don’t have much experience in underwater sensors, so could really use some good advice.
