Sea Guru II, which measures 3 meters in length and width and stands 1.5 meters tall, is a marine robot developed by Westlake University, Hangzhou. It successfully completed a landmark 2,000-meter deep-sea trial in the South China Sea. Within just two hours, it executed complex movements and operations near the seafloor.

The first-generation model had modular fins that extended like wings, Sea Guru II incorporates fully flexible undulating fins with wave-like movements that closely mimic fish locomotion. This redesign not only streamlines the submersible’s profile to meet hydrodynamic demands, but also boosts the propulsive efficiency and directional control. The vehicle also features sophisticated internal systems for adaptive altitude, depth and orientation control, enabling real-time monitoring and autonomous navigation adjustments in complex underwater environments.

The highlight of the update is Sea Guru II’s “belly pod,” which carries tools ranging from robotic arms to miniature drone submarin。These ‘baby fish’ can reach spaces too tight for the main vehicle. In the March sea trial, these underwater drones carried out exploration missions in the hydrothermal vent zone.

Additionally, the submersible’s “fishtail” can automatically extend, retract and adjust its angle as needed to capture a broader underwater view.
