The wave glider converts ocean wave motion into forward thrust by using its two-part architecture, and generates electricity for its control system and sensors by utilizing its carried photovoltaic power system. The wave glider has the capability of fixed-point virtual mooring and autonomous path following, and is featured by long duration and extended scale in cruising observation of the marine environment. This paper analyzes the necessity of developing wave gliders for marine environmental monitoring and introduces the state-of-art of wave gliders in the world nowadays. Then the crucial technologies and key guidelines for successfully designing a wave glider are presented through analyzing its working process, structure and motion mechanism. In addition, this paper approximately solves the basic physical parameters of the third generation wave gliders, before finally summarizing the performance indices of the second generation wave gliders and their wide applications in marine environmental monitoring.
