ELWAVE is an innovative developer of subsea imaging sensors for ROVs (remotely operated vehicles), AUVs (autonomous underwater vehicles) and subsea robotic platforms.

Based on a unique and world-first biomimetic electric sensing technology, our sensors are ideal for a wide range of unmanned underwater vehicle applications in both the civilian and military sectors.

CEDAR – cutting-edge electric sensing technology

Our CEDAR (Controlled Electric Detection And Ranging) technology is inspired by the electrical sensory perception of tropical freshwater fishes, which use this unique capability to navigate, hunt prey, and communicate with each other in challenging environments where sight and echolocation are ineffective.

Undisturbed electric field

electric sensing technology

Electric field disturbed by an object

CEDAR generates a low-frequency AC electric field that is disrupted by objects in the near vicinity, causing changes in current intensity. These disturbances can be measured and used to characterize the underwater environment even in the murkiest of conditions.

OctopulseOctopulse

Seabed imaging solution for AUVs & ROVs

Octopulse is a compact and lightweight imaging sensor based on our proprietary CEDAR technology, and is ideal for a wide range of platforms, including ROVs, AUVs and crawler robots. The modular system utilizes an array of up to eight electrodes with cables up to 7 metres in length, and provides 360-degree real-time detection.

Seabed imaging solution for AUVs & ROVs

The sensor provides highly effective detection, localisation and classification of both metallic and non-metallic objects as well as buried targets. It delivers excellent performance in noisy environments and high levels of suspended sediments, and works both in water and in air. With no moving parts and low power consumption, it can provide contactless characterisation of any kind of surface or material, and is ideal for long-term deployments requiring little maintenance.

Applications

Naval mine and UXONaval & Commercial UXO

Able to detect both ferrous and non-ferrous objects at depths of 1 to 2 metres, Octopulse can be easily used for detection, localization, and classification of targets.

ROV & AUV Navigation

ROV & AUV NavigationWith an effective detection range of up to 5 times the length of the vehicle, Octopulse is ideal for unmanned underwater vehicle navigation and obstacle avoidance, and is an excellent complement to cameras and sonars. Providing real-time situational awareness in 360 degrees, it enables underwater robotic vehicles to operate safely and effectively under highly challenging conditions.

Survey & MonitoringSurvey & Monitoring

Thanks to its contactless detection and characterization abilities, Octopulse provides survey ROVs and AUVs with a critical sensing capability for underwater surveying and the monitoring and maintenance of offshore infrastructure.
