Exail, a global leader in maritime robotics, has selected Elwave’s advanced electromagnetic sensing technology to equip its R7 remotely operated vehicles (ROVs) for an undisclosed client. As part of this collaboration, Exail will integrate Elwave’s Tetrapulse sensors—powered by the innovative CEDAR (Controlled Electric Detection And Ranging) technology—into multiple R7 ROVs.

Enhanced Target Detection with Electromagnetic Sensing

This next-generation biomimicry sensing capability offers significant advantages in subaquatic electrical resistivity mapping. “In the context of target identification and neutralization missions, the integration of CEDAR technology enables superior operational performance in challenging environments, including turbid waters”, explained Gary Bagot, Sales Director at Elwave. The R7 ROVs equipped with Elwave‘s Tetrapulse sensors will improve the detection, localization, and characterization of metallic and non-metallic underwater and buried targets, including steel, aluminum, and fiberglass composites.

Combining the agility of a mini-ROV with the capabilities of an observation-class system, the R7’s modular design supports a range of sensors, tools, and payloads. This versatility makes it particularly well-suited for underwater security missions, including hazardous terrain navigation, UXO detection, and disposal operations.

“By integrating CEDAR technology into the R7 ROV, Exail and Elwave are delivering an advanced solution that strengthens operational effectiveness for underwater exploration, defense, and security applications,” said Nicolas Astruc, ROV Managing Director at Exail. “This collaboration combines Exail’s expertise in maritime robotics with Elwave’s electromagnetic sensing technology to provide customers with a unique and powerful tool for operations in complex environments.”
