Scientists in China have unveiled a new underwater robot that could change the way we explore the ocean. Nicknamed the “Sea Turtle,” this innovative robot is designed to move smoothly just a few centimeters above the seafloor—even in tricky, obstacle-filled terrain like coral reefs. Why This Underwater Robot Is Special Most underwater robots use propellers, which stir up sand and sediment. This not only blocks visibility but can also damage fragile marine life. The Sea Turtle is different. Inspired by real sea turtles, it uses specially angled flippers to glide through the water, reducing sediment disturbance by nearly 90% compared to traditional robots. The result? Clearer images, safer navigation, and less impact on ocean ecosystems. Full-Range Maneuvering Like Never Before What makes the Sea Turtle truly unique is its 360-degree posture control . It can twist, tilt, and glide in any direction—almost like it has tentacles. This allows it to: Squeeze through narrow gaps...
