for Every Operation.
Secure Grip
A secure grip remains locked onto any object until released by the operator.
Easy Swap
Adjustable heads with threaded connections make it easy to swap and orient the arm & attachments for any mission.
Quick Attachment
Quick-attach bracket on the ROVs’ underside offers configurable positions: extended, angled, or vertical.
Intuitive Control
Easily control the arm via a handheld controller. Real-time video and sonar guidance through SubNav OS ROV software.
Attachment Heads
2-Jaw Grabber Head
Enhance the utility of your ROV with our rugged 2-Jaw Grabber Head.
- Max Jaw Opening: 5.18 inches (131.6 mm)
- Locking Force: 85 lbs (38 kg) of consistent grip
- Compatibility: Fully compatible with all ROV models
- Modularity: Interchangeable with all manipulator heads
This grabber is engineered for high-stakes underwater operations:
-
Public Safety & Search and Rescue (SAR): Optimized for the retrieval of drowning victims and recovery of evidence.
-
Underwater Inspection & Maintenance: Ideal for holding inspection tools for leak detection or precision measuring.
-
Scientific Research & Salvage: Excellent for securing lost gear, biological sampling, and clearing debris from critical infrastructure.
3-Jaw Grabber Head
Maximize the handling precision of your ROV with our 3-Jaw Grabber Head. Engineered with a three-point contact, this head provides superior stability and centering for objects that are difficult to secure with standard two-jaw systems.
- Configuration: 3-point contact design for secure gripping
- Max Jaw Opening: 2.13 inches (54.1 mm)
- Locking Force: 85 lbs (38 kg) of consistent grip
- Modularity: Fully interchangeable with other manipulator heads
The 3-Jaw design is specifically engineered for tasks centered on grip:
- Infrastructure Inspection & Maintenance: Ideal for securely gripping pipes, valves, and handles during underwater maintenance.
- Object Recovery: The self-centering geometry makes it the superior choice for grabbing cylindrical objects, rods, or irregular salvage items.
Sharp Cutter Head
Upgrade your subsea intervention capabilities with the Cutter Head, engineered for precision and reliability:
Mechanics: Specialized design for efficient line capturing and tensioning
Blade Capacity: 53 mm diameter cutting blade
The cutter head is designed to make complex remote cutting operations simple:
Anchor & Mooring Management: Safely cut lines and wires in congested areas underwater
Salvage & Gear Recovery: Remove entanglement hazards or recover lost equipment with ease.
Sediment Sampler Head
Bring sediment from the seafloor to the surface for further testing and analysis with the Sediment Sampler Head.
This interchangeable tool is best for scientific research, data collection, and non-destructive testing (NDT).
Frequently Asked Questions (FAQs)
The 2-Jaw grabber is optimized for general retrieval and holding tools, while the 3-Jaw grabber uses a 3-point contact geometry to provide superior stability and self-centering for cylindrical or irregular objects, such as pipes and valves. Choosing the correct head depends on your target object’s shape: the 2-Jaw excels in versatile gripping, while the 3-Jaw is engineered for precision centering on round hardware.
Yes, our robotic grabber arm system is designed for modularity, allowing operators to quickly interchange the 2-Jaw, 3-Jaw, and sharp cutter. and sediment sampler attachments in the field. This modular design enables you to adapt your ROV to changing mission requirements—such as switching from a recovery task to a pipe inspection or line-cutting operation with minimal downtime. For teams that frequently change between two different heads, we suggest purchasing two Robotic Grabber Arms. Assigning one head to each arm makes swapping quick and hassle-free.
The Robotic Grabber Arm and Attachment Heads are specifically engineered for plug-and-play integration with the entire SRV-8 ROV series (SRV-8C, SRV-8, and SRV-8X). This ensures seamless connectivity through the ROV’s dedicated grabber port without requiring complex custom configurations or third-party adapters.
