4-Axis Manipulator

The 4-axis manipulator is a soft-end effector and enhances versatility and precision by providing multi-directional control, allowing for intricate and efficient handling of objects in various applications.

Optional: Soft end-effector for enhanced manipulation

Metal Detector and Magnetometer
  • Underwater metal detector: It is an essential tool for marine missions, utilizing electromagnetic fields to accurately locate metal objects beneath the water's surface.
  • Magnetometer: It serves as a key tool for detecting and mapping magnetic anomalies beneath the ocean's surface, aiding in various applications.
Sonar Systems

By emitting sound waves to the ocean floor, sonar systems generate intricate images of underwater landscapes and objects, facilitating efficient seabed mapping and target detection. In addition to a standard forward-looking multibeam imaging sonar, we also offer the option to install side-scan sonars.

Doppler Velocity Logs

DVLs (Doppler Velocity Logs) enable accurate underwater navigation, altitude maintenance, and real-time velocity measurement by analyzing Doppler shifts from acoustic signals reflected off the seabed. Additionally, they can assess current profiles for flow analysis.

Short Baseline System

Short Baseline System (SBL) utilizes sound waves for measuring underwater depths and determining the global position of the underwater drone. Additionally, it can be outfitted for use by nearby divers.

Environmental Sensors
  • A CTD sensor measures the conductivity, temperature, and depth of water with high precision, providing crucial data for determining essential physical properties of the environment
  • An underwater pH sensor plays a central role in marine studies, as it measures the acidity or alkalinity of the water and thus provides important data for monitoring the aquatic environment.
Custom payload
Upon request, we also offer the option of custom payload integration for your specific applications and needs.
