A design of regulating and compensating tank system for modular Autonomous Underwater Vehicle (AUV)

An Autonomous Underwater Vehicle (AUV) is considered a vehicle that can submerged underwa- ter which contains various systems that includes power and controlled by an on-board computer system, tank systems, rudder controlled systems and manoeuvring system. Submarines use regu- lating and compensating tank to control the stability of the boat. Regulating and Compensating Tank are containers that can store air or water for both sides of the submarines to control the bal- ancing of its body. Regulating and Compensating Tank adjust the pitch without changing the weight or buoyancy balance. The vehicle is fitted with one tank in the middle and one in the port and starboard side. A liquid (water) is moved between the three tanks to shift the weight and con- sequently adjusting the pitch. This project was carried out to propose a new design of regulating and compensating tanks for modular AUV
