Description :

Arya is an Autonomous Underwater Vehicle or AUV. The team that worked on this project consists of undergraduate students of the Delhi Technological University (DTU) in India from varied multidisciplinary backgrounds.

The AUV's mechanical system includes the watertight hulls and the structural framework that house the on-board electronic system. The rationale that has been provided behind this design methodology is to design a stable vehicle that has positive buoyancy and can help in operating as well as modeling the AUV’s control system.

This is accomplished by ensuring the desired aspect ratio of the hydrodynamic stability as well as placing all the components optimally to maintain the required positions of buoyancy and the centre of gravity. In addition to that, the AUV also has an open-frame structure so that it can reduce the drag force it experiences effectively. It is also noteworthy that the AUV has an acrylic framework that supports all its subsystems robustly.

ARYA’s cut-off circuit has also been designed with the safety of electronic circuits and batteries in mind. It consists of MOSFETs, diodes, relays, and comparators. The diodes in the circuit are employed to prevent back current from entering the batteries. Also, two comparators are employed to keep the battery voltage of the AUV between the minimum threshold and the maximum.

Tools of introspection

ARYA’s design can be regarded as the result of a commitment and dedication to develop a robust yet compact and lightweight vehicle. It meets the industrial standards when it comes to its eco-friendliness and safety to function effectively in shallow water as well as a 5-25 meters depth range.

ARYA’s development offers a favorable platform for future advancements by improvising parts of the vehicle. For instance, by integrating different advanced sensors to enhance the application of the AUV in detecting and monitoring the marine structures and habitat.
