Click the payload tools
- 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.
- CP Probe: contact probe that provides a means of carrying out underwater cathodic protection potential measurements
- UT Probe: ultrasonic thickness gauge for accurate, through-coat measurements as specified by classification societies
- Cavitation cleaner: high pressure equipment with adjustable intensity for minimal impact on coatings and surfaces, ensuring readiness for accurate contact-based measurements of structures
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.
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 (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.
The 3-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 or cutter for enhanced manipulation.
