Marine engineers have various job responsibilities in the industries like shipping, ship manufacturing, steel industry, power sector, manufacturing sector, consultancy firm. They design, construct and develop nautical equipment. After completing marine engineering courses candidates can option for lucrative career options in public and private shipping companies, engine production firms, ship building and designing firms, navy, research bodies. After graduating as a marine engineer, one can get a job in a ship as a third assistant engineer or fourth engineer. They can also get employed in different foreign and Indian shipping companies.

I would say it's yet to gain momentum. It would be easier to explain if the question has specialisations in robotics. Robotics has several aspects: mechanics, motor controls, sensors and actuators, vision, computing, and intelligence. There are numerous companies working on these fields individually, but there are hardly few companies working on all of these domains or on a robotic product as such. If you consider Machine Intelligence, you will find several startups and MNCs. They work on amazing fields like machine learning, big data, modelling and planning, but their concentration is not exactly on Robotics but in the fields like finance, stocks, investments, and advertising etc. On the vision and computing part, there are quite a lot of companies working on embedded systems and image processing. They target automobile, consumer electronics, and industrial automation sectors. Working on robotics is a fad in almost every engineering colleges these days. Usually, they build line followers, wall followers or at most a maze solving robots. You can even get a ready to use kits to build these robots. Given that the global players (like Google) are investing in Robotics; increase in amateur robotic enthusiasts. Open source tools and platforms available for robotics, we can be assured of significant development in this field in another 5-10 years. This would need a little push from academia (in including relevant courses) and government (to support set up new industries).
