The Present Status of Environmental Energy Harvesting and Utilization Technologyof Marine Robots

Energy supply is an important limiting factor for work capacity of the marine robots, harvesting energy directly from ocean environment is an ideal way to increase energy supply, improve the endurance and load capacity of marine robots, and achieve long-term uninterrupted work. Various forms of ocean environmental energy and their characteristics are introduced in this paper, according to the classification of energy forms, the present status of marine robots surrounding environment energy harvesting technology are introduced. Finally, the characteristics of marine robots environmental energy harvesting and utilization are summarized and the key technologies in the future are discussed.
