Penguin-inspired Underwater AI Robot for Environmental Monitoring

Updated: May 11 2024 04:00
EvoLogics, a Berlin-based underwater technology company, has recently announced the launch of the next-generation Quadroin AUV (autonomous underwater vehicle). This robot draws inspiration from the hydrodynamic body shape of the Adélie penguin, resulting in a fast and maneuverable underwater vehicle designed for monitoring and surveying applications.



The distinctive, penguin-like design of the Quadroin AUV is a result of EvoLogics' expertise in low-drag bionic design. Dr. Rudolf Bannasch, the founder of EvoLogics, has conducted extensive research on penguin locomotion, which has contributed to the AUV's exceptional hydrodynamic properties. This unique design allows the Quadroin to achieve speeds of up to 10 knots while minimizing energy consumption, enabling versatile deployments.



The initial series of Quadroin prototypes were developed in collaboration with the Helmholtz-Zentrum Hereon research institute for the Helmholtz Association's MOSES (Modular Observation Solutions for Earth Systems) initiative. These prototypes focused on monitoring ocean eddies and were equipped with sensors for collecting various physical water parameters, such as temperature, pressure, oxygen, conductivity, and fluorescence, at different depth levels.


The new generation Quadroin features an expanded instrument payload, which includes:

• Side-scan sonar for acoustic seafloor imaging
• Two full-HD underwater cameras (one forward-facing at a 45-degree angle and one downward-facing)
• Dimmable LED lights for visual identification of the vehicle's surroundings

The Quadroin now integrates EvoLogics' AI-powered object recognition module, which allows objects to be detected in the side-scan sonar and video feeds live during the mission. The processing is carried out onboard the vehicle, enabling automatic collision avoidance through a front-looking sonar system.


The Quadroin boasts impressive performance capabilities:

• Maximum depth: 150 m (492 ft)
• Top speed: 18.5 km/h (11.5 mph)
• Payload capacity: 3 kg (6.6 lb)
• Battery life: 10 hours of runtime at a cruising speed of 7 km/h (4.5 mph) after a six-hour charge

The robot also features an integrated Nortek Nucleus1000 subsea navigation package, which includes Nortek's DVL (Doppler Velocity Log) technology and additional position-aiding sensors to ensure reliable vehicle control.


The next-generation Quadroin AUV by EvoLogics represents a significant advancement in underwater robotics, combining bionic design inspired by penguins with cutting-edge technology and enhanced performance capabilities. With its expanded instrument payload, AI-powered object recognition, and improved navigation, the Quadroin is poised to revolutionize underwater monitoring and surveying applications. EvoLogics will be presenting the upgraded Quadroin at Oceanology International 2024 through live on-site demonstrations.
