Wave energy is obvious source for renewable energy harvesting in oceans. A new WEC named wave turbine was proposed. The proposed system consists of a floating body and a submerged body. The floating body is same with that of a conventional buoy, and the submerged body is a power take off similar to a turbine which has flap-type blades in a round-frame rotor. To describe the proposed system, we developed...
The robotic buoy which is a mobile mooringless buoy and keeps position autonomously against ocean current.[1][2][3] The robotic buoy is specialized for operating on an environment where is too deep to anchor for mooring, like middle of an ocean. The robotic buoy is compose of two systems, propulsion system and energy harvesting system. ‘Wave Turbine’ is a PTO(Power take-off)[4] to harvest oceanic...
In this paper, we described about development of a robotic buoy for Internet of maritime thins (IoMT) technology. For IoMT, stand-alone data conllector is a key technology. The energy harvesting robotic buoy is proposed in the context. The proposed system is composed of three components: propulsion system, energy harvesting system, and buoyancy control system. The proposed system can hold its position...
For long-term operation, a wave-energy harvesting robotic buoy system that holds position automatically without anchoring line is proposed. We made a prototypes which consists of the propulsion system and power generation system. We adopted the Wave glider platform to hold the buoy position without mooring, and developed a flip-type self-rectifying wave turbine system (WTS). We developed modeling...
