The HONPINE M Series underwater collaborative robot is a heavy-duty subsea system for offshore operations, featuring a 4+1 DOF design for high-load tasks such as component handling, installation, and subsea cutting.
Made from AL6061 aerospace-grade aluminum with hard anodized treatment, it offers strong corrosion resistance. The system weighs 15 kg in air and 8 kg underwater, reducing ROV load, while delivering 12 kg payload, 1000 N gripping force, 1500 N cutting force, and 30 N·m wrist torque. The J5 joint provides a 0–200 mm range, and it operates at depths up to 300 m.
It uses servo motors, supports position control and ROS integration, and is compatible with master-slave teleoperation for intuitive remote operation. This underwater robotic arm system is designed for high-intensity offshore applications requiring strength, precision, and flexible control.
