The AUV DeDAvE has been under development from 2013-2015 to create a versatile and compact vehicle that is easier to handle than existing systems while providing more space for payloads and fast turn-around times. DeDAvE is able to operate in ocean depths of 6,000 meters. DeDAvE is equipped with state-of-the-art sensor systems, easily exchangeable battery and data storage modules and a distributed control infrastructure. This allows the AUV to adapt to very different mission tasks, to integrate additional actuators (like bow dive planes or thrusters) and to add more battery capacity (into the payload area).
The modular design of the DeDAvE AUV creates a family of AUVs for different diving depths, mission durations and payload requirements. The DeDAvE AUV consists of a number of individual sections that hold the different vehicle components. The bow section contains the obstacle avoidance sensors, one emergency weight drop system and the (optional) diving plane. By default, two energy sections with eight battery modules are located near bow and stern. The control and navigation section houses the control computer, the inertial navigation system, an acoustic modem with USBL function, the emergency and communication unit (with backup battery) and a sound velocity sensor. The AUV can handle Payload interfaces like Ethernet, serial port or CAN bus.
