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. Key Features 7 kg Grabbing Force — Powerful enough for clamping, dragging, and retrieval operations at depth across all three tool head configurations. 170 mm Max Jaw Opening — Accommodates a wide range of object sizes, shapes, and geometries for versatile underwater manipulation. 100 m Depth Rating — Rated for serious underwater work across all tool heads in demanding inspection and scientific environments. Modular Quick-Swap Tool Heads — Field-swap between Robotic Claw, Circular Claw, and Sediment Sampler without tools or complex disassembly. One arm, three missions. 10° Elevation Design — Optimized camera angle for improved operator visibility during active manipulation tasks. Aluminum Alloy Construction — Lightweight, durable, and corrosion-resistant with a high-reliability sealing connector for sustained depth performance. Compatible with M2, M2 S, M2 PRO & M2 PRO MAX — Available in two platform-specific variants (CRA02 and CRA02-PM). Select the correct version for your ROV at checkout.
