Underwater Manipulation, Reimagined. The CHASING Grabber Arm 2.0.
The CHASING Grabber Arm 2.0 is a high-performance modular robotic arm accessory for the CHASING M2, M2 S, M2 PRO, and M2 PRO MAX underwater ROVs. Delivering 7 kg of grabbing force, a 170 mm max jaw opening, and a 100 m depth rating, it enables precise clamping, dragging, retrieval, and sampling operations that were previously beyond the reach of compact ROV platforms. A quick-swap tool head system supports three purpose-built attachments — Robotic Claw, Circular Claw, and Sediment Sampler — without changing the arm body.
