3-Finger Robotic Arm (W6 Version) — Adaptive Subsea Manipulator for FIFISH W6

Equip your FIFISH W6 ROV with true intervention capability. The 3-Finger Robotic Arm (W6 Version) is an industrial-grade, adaptive manipulator engineered for precise gripping, safe retrieval, and light underwater tasks. Its three-finger geometry conforms to irregular shapes, while smooth proportional control lets you place, pick, and hold with confidence—even in surge and low-visibility conditions. Built from marine-grade materials and sealed for long-term use, this gripper integrates cleanly with the W6 payload bay for a streamlined, plug-and-play setup.

Why this gripper stands out

• Adaptive three-finger design: Curved, interlocking fingers create multiple contact points for a stable grip on rounded, flat, or oddly shaped objects such as samples, tools, rings, and small debris.

• Proportional open/close control: Fine-tune finger speed and position directly from the W6 console, enabling delicate handling and secure clamping when needed.

• Optimized for FIFISH W6: Quick-attach mounting, balanced form factor, and camera-aligned working envelope keep the manipulator within the W6’s field of view for accurate operation.

• Marine-grade build: Hard-anodized alloys, 316 stainless fasteners, and robust sealing deliver dependable performance in saltwater environments.

• Low-drag profile: A compact, streamlined body minimizes disturbance to W6 trim and stability, helping you maintain position while manipulating.

• Plug-and-play power & control: Draws power from the W6 payload interface and responds natively to the W6 controller—no external battery packs or custom drivers required.

What you can do with it

• Search & recovery: Retrieve small objects, lift loops, carabiners, tools, and evidence without damaging sensitive surfaces.

• Environmental & scientific work: Collect samples, place sensors, and manipulate lightweight apparatus during surveys and habitat studies.

• Inspection & maintenance support: Hold tags, route small lines, and assist with light intervention during hull, pipeline, and structure inspections.

• Aquaculture & fisheries: Remove entanglements, retrieve equipment, and handle routine husbandry tasks with safer, repeatable control.

• Education & training: Teach real subsea manipulation techniques—approach, alignment, grasp, and placement—in a controlled, camera-guided workflow.

Built for real underwater conditions

The W6 version of the 3-Finger Robotic Arm is designed to operate wherever your FIFISH W6 can go, with materials and sealing that resist corrosion and fouling. The manipulator’s balanced geometry reduces unwanted yaw or pitch when gripping, while smooth actuation helps prevent stirring sediment that could obscure the camera. After each dive, a quick freshwater rinse keeps everything mission-ready.

Simple installation & operation

1. Mount the arm to the W6 quick-attach payload bay.

2. Connect the payload interface cable—power and communication are handled automatically.

3. Control finger open/close and speed from the W6 console for precise placement and secure holding.

Compatibility: This W6 variant is engineered specifically for the FIFISH W6. For V6 or V6 Series ROVs, select the V6 Series version of the 3-Finger Robotic Arm.

Best-practice tips for clean, confident grabs

• Approach the target head-on using the W6 camera to keep the object centered.

• Use short bursts of thruster input while closing the fingers to maintain position.

• Start with slow, proportional closure to seat the fingers, then tighten as needed.

• After retrieval, stow the item in a basket or hold stable while returning to the surface.
