The ROV-1500 from Outland Technology represents a leap forward in underwater robotics, a compact remotely operated vehicle (ROV) weighing in at less than 40 lbs (19kg) the ROV- 1500 is easy to transport and deploy. Similar to Outland’s previous models, the ROV-1500 shares an easy to use con- trol system and topside power. Field replaceable components continue to make maintenance a breeze.

EvoLogics launched the next iteration of the Quadroin AUV.

Originally introduced in May 2021, the Quadroin vehicle gar- nered attention for its distinctive, penguin-like design. Engi- neered for monitoring and surveying, the fast and maneuverable

Quadroin leverages EvoLogics’ expertise in low-drag bionic design. Dr. Rudolf Bannasch, EvoLogics founder, delved into years of research on penguin locomotion, resulting in the AUV’s remarkable hydrodynamic properties. With its low-drag shape,

The initial series of Quadroin prototypes, developed in col- laboration with Hereon for the Helmholtz Association’s MO-

SES initiative, focuses on monitoring ocean eddies. These ve- hicles are equipped with sensors for collecting geo-referenced data on various physical water parameters, including tempera- ture, pressure, oxygen, conductivity, and ? uorescence, at dif- ferent depth levels.

Building upon this foundation, EvoLogics has undertaken signi? cant enhancements to the Quadroin platform, with a pri- mary focus on expanding its instrument payload capacity and underwater AI computations. This evolution led to a compre- hensive redesign of the vehicle’s internal layout, integration of updated components, and optimization of sensor systems to accommodate a broader range of instruments while maintain-
