bionic uncrewed underwater vehicles
Over years of R&D work for various projects, EvoLogics robotics team came up with innovative uncrewed underwater vehicles with cutting-edge bionic designs that took the best features from their wildlife counterparts.
Envisioned as sensor carriers for automated monitoring missions, the three latest UUVs are entering the final stages of development for commercial use.
These include the PingGuin AUV, the Poggy AUV, and the MiniROV hybrid robots.
PingGuin is an autonomous vehicle with low-drag bionic design.
One of the EvoLogics co-founders, Dr. Rudolph Bannasch studied Adélie penguins and the effectiveness of their locomotion since the 80s, undertaking several field trips to the Antarctic and performing numerous wind tunnel and water tank experiments in Berlin. This research demonstrated that spindle-shaped flow bodies, modeled after penguins, achieve ultra-low drag coefficients in the water.
Hence, the design choices for the vehicle’s components were directed at maintaining the shape and contour of an idealized penguin-like spindle to maximize the drag efficiency, so the AUV has very few protruding parts that affect its hydrodynamic performance.

Poggy is a bionic autonomous vehicle based on the Fin-Ray® technology.
The AUV is a one of a kind, novel bionic design with two propulsion thrusters and two independent flexible “tails” that give the robot unique mobility features.
Its dual-tail construction is an original idea that stemmed from previous work on EvoLogics’ Manta Ray AUV and its lifelike “flapping wing” propulsion system. The design was simplified and optimized - the robot lost the wings, and its tail was divided in two.
Both parts of the dual-tail use independent bionic Fin-Ray® drives and allow for precise heave, pitch and roll adjustments, enabling dynamic climbs and dives, leveled gliding and bottom following.
Due to the small size of its basic AUV components, Poggy has an excellent payload capacity and can carry multiple sensors and instruments at the same time.
In addition, the dual-tails facilitate unique maneuvers that could open new opportunities for detailed sensing and monitoring: the vehicle was designed to keep any desired roll angle and maintain a steady glide, even at very low speeds.

MiniROV is a turtle-shaped underwater vehicle that can operate both as a tethered ROV and a tether-free AUV.
Currently under development, the modular miniROV is targeting applications where stable position keeping and hovering is crucial to perform precise operations on and around underwater infrastructure.
