The invention relates to a seaborne detection robot which comprises a waterborne floating body device, a middle connecting device and a power driving device. The waterborne floating body device adopts a ship-shaped structure, stabilization bodies, an airtight cabin, a solar cell panel, a GPS, a communication antenna and a sensor are arranged on the waterborne floating body device, and the airtight cabin is internally provided with a storage battery and a communication controller; the middle connecting device is a flexible cable made from special materials and can transmit electric energy, signals and kinetic energy; and the power driving device comprises a wind energy driving assembly and a wave energy driving assembly. According to the seaborne detection robot driven by both wave energy and wind energy, the purpose of making the seaborne detection robot to sail along a preset track is achieved by jointly utilizing renewable sources of wave energy and wind energy as direct driving force, an underwater glider driven by wave energy as active power to pull the waterborne floating body device to move forward underwater and thrust generated by a propeller driven by wind energy as auxiliary power and automatic cruise control of the communication controller.
