Under Water Robotics

This unique course is aimed at giving the budding engineers the deep insight to what exists deep beneath the water and why is it difficult to navigate inside water. Scientists and engineers all over the world are working towards this very different field of science, what we call it as Underwater Robotics. The Students will know about the various mechanism considering the modularity and hydrodynamics of water vehicles including Autonomous Underwater Vehicle popularly known as AUV, Remotely Operated Vehicle, Submarines and Ships. The second part will be its control system. We will move from the discussion of Remotely Operated ones to Autopilots and Dynamic positioning. Some understanding of physics is expected.

Charges: Rs 5400/- per team with maximum four members.

The Charges includes:

• Training fee of the 2 day workshop
• Participation certificate
• Additionally, a detailed manual will also be provided to each participant .

Free Takeaway Kit to One Team.

We conduct workshops on two consecutive days. Each day has an eight hours session (in total 16 hours). This is properly divided into theory and hands-on sessions.

The faculties are people from top academic institutions, industries and research institutions. They have experience in the industries at the same time had the best education in this field. In fact some of them are pursuing master and Doctorate at Top notch universities to build their knowledge base.
