Dive into the world of underwater exploration, and you’ll find a new player making waves: HERO-BLUE. This isn’t your average remotely operated vehicle (ROV); it’s an innovative robot designed to tackle the challenges of the depths of the sea with a unique set of skills.
HERO-BlUE by the numbers
HERO-BLUE is a proof-of-concept robot, measuring 31.5 inches by 23.6 inches by 11.8 inches and weighing 24.9 pounds. It’s remotely controlled, but with its stereoscopic vision, the future could see HERO-BLUE operating autonomously, leading the charge in underwater exploration and research.

A new breed of ROV
HERO-BLUE stands for “Hazardous and Extreme Environment Robot for Biomimetic multiLocomotion-based Underwater Expedition.” Developed by Taesik Kim and his team at South Korea’s Pohang University of Science and Technology, this experimental device is inspired by the natural world. HERO-BLUE is equipped to swim, walk, and crawl its way through the most challenging environments. The journal IEEE Transactions on Robotics has recently featured a publication detailing the research.

Swimming against the current
Traditional ROVs rely on electric thrusters to navigate the watery depths. However, these thrusters have limitations—they can get clogged with debris or struggle against strong currents. Enter HERO-BLUE, the robot that’s not just making a splash but is set to revolutionize underwater missions.

Fin-tastic design
What sets HERO-BLUE apart are its four multimodal fins and two lateral fins. These aren’t just any fins; they’re made of polymer panels connected by elastomer tendons, allowing them to be rigid or flexible as needed. This design enables HERO-BLUE to adapt its movement strategy on the fly – flapping through the water like a fish or walking along the seabed when currents prove too strong.
The backbone of innovation
In shallow waters where swimming isn’t feasible, HERO-BLUE’s salamander-inspired spine comes into play. This flexible backbone allows the robot to wriggle forward, ensuring progress even in the trickiest conditions.
