Hi, I am designing a drone that goes underwater to collect data such as PH, temperature and salinity for my senior design project in University. The main issue I’m facing is the bouyancy engine. The traditional way of using a long drive shaft to pull the shafts of the syringe takes way too much space. I came across your bouyancy engine and it seems to be the perfect solution. The acrylic tube I’m using for my drone is 4” OD and 3FT in length so it needs a lot of water to sink. The 150ml syringe you use won’t work especially since it can only take half of the capacity due to the drive shaft inside.
Is there anyway I could get the solidworks files for the parts of the bouyancy engine so that I could scale it up to a large syringe? I’m looking to do the same thing for a 400ml syringe.
Also is there another way of doing this and saving space without doing it the traditional way?
