EvoLogics presents Quadroin bionic underwater robot

EvoLogics, a Berlin-based provider of high-tech underwater robotics, data networks, positioning, and sensor technologies, has announced the launch of the next iteration of the Quadroin AUV. The Quadroin vehicle, with its distinctive, penguin-like design, was initially introduced in May 2021 and quickly became a topic of discussion. 

The AUV is engineered for monitoring and surveying and is fast and maneuverable. EvoLogics’ expertise in low-drag bionic design has resulted in the Quadroin’s remarkable hydrodynamic properties, achieving speeds of up to 10 knots while minimizing energy consumption and enabling versatile deployments. 

Dr. Rudolf Bannasch, EvoLogics founder, has conducted years of research on penguin locomotion, which has contributed to the AUV’s exceptional performance.

The initial series of Quadroin prototypes were developed in collaboration with Hereon for the Helmholtz Association’s MOSES initiative. These prototypes are focused on monitoring ocean eddies and are 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 carries an expanded instrument payload, which includes a side-scan sonar for acoustic seafloor imaging and two full-HD underwater cameras – one forward-facing at a 45-degree angle and one downward-facing – with dimmable LED lights for visual identification of the vehicle’s surroundings.

The newly integrated EvoLogics AI-powered object recognition module and the redesigned hardware and propulsion systems for the Quadroin will allow objects to be detected in the side-scan sonar and video feeds live during the mission, with processing carried out onboard the vehicle. It also enables automatic collision avoidance through a front-looking sonar system. 

The robot can dive to a maximum depth of 150 m (492 ft), has a top speed of 18.5 km/h (11.5 mph), and can carry up to 3 kg (6.6 lb) of gear. Its lithium-ion battery pack reportedly provides 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 AI object recognition module to detect items picked up by the sonar or cameras, as well as an integrated Nortek Nucleus1000 subsea navigation package that helps it keep track of its whereabouts.

The hardware and propulsion systems of the Quadroin have been redesigned with next-generation components for better performance. The vehicle now features a Nortek Nucleus1000 integrated subsea navigation package, which includes Nortek’s DVL technology and additional position-aiding sensors to ensure reliable vehicle control.
