DTU AUV represents a technological dream achieved by a team of undergraduate Delhi Technological University (formerly Delhi College of Engineering) students to develop an Autonomous Underwater Vehicle of industrial standards. It tests its progress against the world by participating in reputed RoboSub competition organised by AUVSI every year in San Diego, USA. The vehicle has been designed by fusion of research work in the field of mechanical engineering, electronics , instrumentation, image processing and acoustics . It is a submersible, untethered robot that is capable of performing shallow water complex tasks without aid from human operators. This project showcases the viability of this kind of robot not only as a research test bed, but also as a useful platform for shallow water applications. It has been designed with a view to achieve maximum operational standards, minimal payload and power requirements and high level of modularity.
