Finally! It’s about time you started pulling your weight around here, bubbles. Researchers at the University of Hawaii have created microscopic “bubble robots” to manipulate very small objects. By using an infrared laser to heat areas of the fluid surrounding the bubble, researchers were able to steer the...
If you created a robot, what would it be like? I would probably build a battery-powered android, because I think I would have the most fun with either a sassy maid-bot or a pretend-little-sister-bot. Scientists in Texas and Virginia were a little more creative, having built "Robojelly," a jellyfish robot that runs on hydrogen and oxygen!
This little swimmer currently gets its fuel from tubes connected...
Have you ever wanted to trick a fish? Of course you have. And now, through the miracle of robotics, we can make that dream a reality. Researchers at the Polytechnic Institute of New York University have invented a robotic fish that moves realistically enough to cause real fish to follow it in a school. In the process, they have learned (at least partly) what makes a leader among fish: beating its tail rapidly. This creates a wake in which other fish can follow with less tail movement, which...
