A Boston-built robotic sea turtle avoided obstacles 91% of the time in 2026 tests while following real fish underwater, according to reports. The result points toward more capable autonomous underwater robots for marine research, environmental monitoring and other applications where tracking live sea life is required.
- 2Robot submarine vanishes after mapping strange structures under Antarctic ice▼A robot submarine mapped strange structures under Antarctic ice, then vanished without a trace
A robotic submarine deployed beneath Antarctic ice mapped unusual structures on the seafloor before disappearing without a trace. The lost vehicle reportedly recorded strange formations under the ice shelf before contact was cut off. The disappearance has drawn attention because the sub was gathering rare data from one of the least explored environments on Earth, raising questions about what it found and why contact was lost.
- 3US reef robot finds coral pillar with 25 times more fish▼In 2026, a US reef robot found one coral pillar hiding nearly 25 times more fish and followed reef sounds
A US underwater robot has located a coral pillar hiding nearly 25 times more fish than surrounding reef, using reef sounds to navigate and identify hotspots. The 2026 finding suggests acoustic monitoring could transform how scientists survey reefs and prioritize conservation of dense fish habitats.
- 4NOAA robot lab probed Lake Erie toxic algae in 2021▼In 2021, NOAA sent a robot lab beneath Lake Erie’s toxic algae and got water-safety readings in under two
In 2021, NOAA deployed an underwater robotic laboratory beneath Lake Erie's toxic algae blooms, delivering water-safety readings in under two hours. The system allows researchers to monitor harmful algal blooms in near real time, helping officials assess risks to drinking water and recreation far faster than traditional boat-based sampling allows.
- 5Underwater robot recovers missing boater's body from Colorado reservoir●Missing boater’s body recovered from Colorado reservoir by underwater robot
Divers in Colorado have recovered the body of a boater who went missing in a reservoir, using an underwater robot to locate and retrieve the remains. The remote-operated vehicle allowed search teams to work in conditions too deep or hazardous for human divers, bringing a weeks-long search to a close.
- 6Oarfish fins inspire large underwater robot design▼Mysterious oarfish’s fins inspire large underwater robot design
Researchers at Cornell University have designed a large underwater robot modelled on the oarfish, a deep-sea creature known for its long ribbon-like body and distinctive dorsal fin. The team studied how the fish propels itself with a rippling fin along its body and reproduced that movement in the robot, aiming for efficient, stable swimming at scale for future underwater exploration.
- 7Oarfish fins inspire design of large underwater robot▼Mysterious oarfish's fins inspire large underwater robot design
Engineers have developed a large underwater robot modelled on the oarfish, a deep-sea fish known for its long ribbon-like body and distinctive fin-based swimming. By copying how the oarfish propels itself with a dorsal fin while keeping its body rigid, the researchers aim to build a more efficient vehicle for long-range ocean exploration and monitoring.
- 8New robot flies, sails and swims autonomously▼Transformative new robot that can fly, sail, and swim autonomously
A newly unveiled robot can fly, sail on the water's surface, and swim underwater, switching between modes autonomously without human control. The multi-domain machine, covered by Popular Science, is being highlighted as a transformative step in robotics, with potential uses in exploration, environmental monitoring and rescue missions across air, sea surface and underwater environments.
