Ingenious Underwater Drone Can Transition to Flight in Less Than a Second:

Ingenious Underwater Drone Can Transition to Flight in Less Than a Second:

Robots have traditionally been purpose-built to perform a single, very specific task, but researchers from Beihang University are taking a much different approach with a new robotic drone: that can operate underwater just as easily as in the air, and it features a clever, nature-inspired trick for maximizing its range. When you think of robots, … Read more
