Autonomous Underwater Vehicle (AUV)

PRESENT WORK

In this present work, a Hybrid AUV SEA (Safina – E- Aabdoz) has been designed on simple hydrodynamic principles to achieve precise underwater movements and control so as to facilitate oceanographic observation. An indigenous control system is developed for this Underwater Vehicle moving in 3D space and having four thrusters, two situated on the bottom provide forward and backward motion and the two servo controlled motor situated on side control the rotation and upward and downward movement of the vehicle. Apart from this, a Robotic arm is also attached to pick and drop objects at precise location.

The main objective of the present study are:

1. Design Autonomous Underwater Vehicle needed for ocean observation.

2. Keep its weight optimum for desired operation.

3. Design AUV of less than 0.5 m length and 0.4 m diameter.

4. Design under water vehicle such that it can bear 25 m of water pressure.

5. Follow the assigned path, pick and drop objects from and to the specific bins.

6. Device an automatic control for the vehicle to make it autonomous.

SIMULATION

The analysis of the hull is carried out by using SolidWorks software. The results obtained from the analysis shows that 4mm thickness of the hull is sufficient to withstand with a hydro static pressure over a depth of about 25 meters as shown in figure.
