Unlike the larger ships, the various wave motions have a considerable effect on comparatively smaller ships. The heave, pitch and roll motion of the ship creates many problems like difficulty in safe landing of a helicopter, spilling of valuable fluids, handling of fragile objects, accurate positioning of weapons, etc. Our aim in this project is compensating the motion of the ship by using a Stewart platform. It is a 6 degree of freedom parallel robotic platform. In the project compensating mechanism will function by keeping upper plate stable irrespective of the motion of the base plate or ship. This is done with the help of gyroscopic sensors, actuator, and microcontrollers. The scaled model consists of servo motors as rotary actuators and on experimentation, it is found that it can compensate the pitch and roll of baseplate by an angle of about +20? to -20? satisfactorily. In actual implementation, linear actuators will be used to take up higher loads and for smoother operations. The project also finds application in steady transferring of goods, for laying foundations for oil rigs. It can be used as stable helideck and can be used by creating a stable bridge for transportation of technicians for maintenance of wind farm.
