Title:

Drift-RMT

The objective of this project is to create an ocean surface drifter buoy that utilizes the ocean's wave energy to power data acquisition and transmission. There are over 1,200 drifter buoys deployed across the globe, with a short lifespan largely due to battery malfunctions. To improve the lifespan of drifters, Drift-RMT (Rotating Mass Technology) was created. Our drifter design features an internal rotating mass that harnesses the energy of ocean waves as the drifter rides the sea surface. Ocean surface drifters are vital instruments for weather prediction, climate mapping, disaster preparedness, plotting shipping routes, fish population monitoring, and oil concentration detection, to name a few. Through a combination of theoretical analysis, simulation, and experimentation in the UNH wave tank, the technical design team crafted a device that uses the pitch and roll of the drifter to generate power for the sensors onboard.
