Sponsored by DARPA (Defense Advanced Research Projects Agency), AeroVironment has created a tiny mechanical flying robot that can fly as real birds. The mini robot is shaped like a hummingbird, remotely-controlled without an external power source to fly, hover, mover forward and backward in the air.
Traditional helicopter is driven by spinning blades, but DARPA is developing a new kind of helicopter which comes with a spinning disc rather than blades.

DARPA have developed this new fin which could simulate the swimming way dolphin. It is said that, by using this new fin, diver could swim 150% faster than before. [Read the rest of this entry...]
This is a MIT project funded by DARPA, which could help soldiers to carry more device with less energy. The advantage of this gadget better than other similar ones is that it is only based on one watt power source. [Read the rest of this entry...]
