Design an underwater robot from the ground up to be easy to make. This ROV is designed for education, exploration... the use of this ROV are only limited by your imagination.
This project was initiated by ROVMAKER.
It's customized professional solid buoyancy material, 6.5Mpa ,300m depth in water, 250kg/m3. This solid buoyancy material is usually used in Marine engineering equipment.
The weights are lead materials, 200g each.
The weights are mounted at the bottom, the frame has some slots to adjust the position and quantity.
Counter weight number and installation position according to the actual buoyancy situation, eventually make the ROV in the water is less than a centimeter leak out of the water, at this point the ROV has a slight positive buoyancy (close to zero buoyancy).
It's always the first to design the thruster. We all know the ordinary RC brushless motor can operate underwater, but once you get into seawater, there will be serious damage. So a special manufacturing processes are designed to protect all parts of motor. However, it is a regular process to clean with water after launching, everybody should do with seawater used equipment.
Thruster are completely protected, and we've already brought the thruster into mess production. Esc is located in part of the aluminum part of the installation, and sealed by resin, which can quickly dissipate heat.
2kg power, 350kv, 30a ESC, 12N/14P, 5600rpm，3s-6s, 10A max .
We used NI PXI to build a test platform.The ESC in thruster:
