Energy system technology for underwater robots

Energy Systems: A collection of devices that provide power sources for underwater robot movements and power devices, instruments, and mission loads. Energy is the main factor that limits its operation - usually limiting the mission parameters of the voyager, such as its range, speed, working depth, and mission load.

Underwater robots, especially autonomous navigational robots with high battery life, require small size, light weight, high energy density, repeated use, safety and low cost.

The underwater robotic energy system uses batteries, yen, internal, battery and hot air machines to ensure that the aircraft has the independent energy needed for safe navigation and operational tasks. Due to the need for size and safety, batteries are the primary energy method used by the robots.

The current energy system also mainly includes thermal system and electro-chemical energy system.

Thermal systems are the thermal and mechanical energy that converts energy into the robots, including closed cycles, chemical and nuclear systems. It is a more practical method to provide energy to the robot underwater by chemical reaction (lead-acid battery, silver-zinc battery, battery).

Electro-chemical energy systems are the performance required for systems that utilize proton-exchange membranes, which later meet the power of underwater robots. The battery is characterized by high energy density, high efficiency generation of electrical energy, less heat at work, it can quickly start and close. However, the technology still lacks suitable quiet pumps, gas line arrangements, solid electrolytes, and effective storage methods for fuel and oxidants. With the continuous development , it is expected to become the leading energy system of the robots.
