Nice to meet this forum.
Hope that “general discussion” is the right place to write about this topic since so far is just an idea
I am on a project regarding the building of a seaglider. I am thinking in purchasing most of the parts from Blue Robotics but I have some doubts if they can actually be used for this.
First and just to clarify it, the seaglider I want to build is as those used for marine research: hydrodynamic hull, two kinds of wings to glide up and down and a ballast tank in their inside.
To simplify the concept I’ve thought in add a pressure sensor (the bar 30 in instace) and program the full system that to a certain depth the glider release the water from the hull and when getting another certain depth at shallow waters, drag the water outside the hull.
The ballast tank I’ve thought to, would be as follows: a T-200 motor (with cable and penetrator included) with some 3d printed centrifugal blades and cage attached to it for using it as a water pump. The water would get into a balloon that, at the same time, would be inside the hull.
So here arrive my doubts:
Since all the electronics and power system would be in the same place that the balloon: wouldn’t the stmospheric pressure created when the baloon inflates, damage the electronics or battery?
How could I seal the tube for transporting the water inside the baloon around one of the hole’s cap?
Can actually be the T-200 motor be used as a water pump with the blade’s modification I’m planning to do?
Thanks in advance.
