IntroductionThe HONPINE M Series underwater collaborative robot is a heavy‑duty subsea manipulator designed for offshore operations such as component handling, installation and subsea cutting. Available in M3 (2+1 DOF) and M5 (4+1 DOF) variants, the system is manufactured in AL6061 aerospace‑grade aluminum with hard anodized treatment and rated for operation to 300 m depth. Typical M5 mass is 15 kg in air and 8 kg underwater, with a rated payload of 12 kg.
Features- Heavy‑duty subsea performance: 12 kg rated payload; gripping force up to 1000 N (M5) / 100 N (M3); cutting force 1500 N; gripper range 0–200 mm; cutting stroke 0–20 mm.
- Lightweight marine deployment: reduced underwater mass (example M5: 15 kg air / 8 kg underwater; M3: 11.5 kg air / 5.5 kg underwater) to lower ROV/platform load and improve maneuverability.
- High‑speed actuation: wrist torque up to 30 N·m; fast end‑effector responses (typical gripping ~4.5 s; cutting ≤8 s; specified gripper times ≤8 s for M3 and ≤11 s for M5).
- Control & integration: servo motor drives; position and speed control modes; ROS support (M5); RS485 and Ethernet interfaces (variant dependent); compatible with master‑slave teleoperation.
- Full‑range motion: J1/J4 continuous ±360° (where indicated); J2/J3/J5 typical ranges 0–170° depending on configuration; flexible 4+1 DOF architecture for confined subsea tasks.
- Marine‑grade corrosion protection: AL6061 body with hard anodized surface for long‑term seawater resistance.
