The video you see above is the on board footage of the DelFly2 autonomous ornithopoter robot. Weighing 16 grams, it carries a small camera and can provide a live feed. If you’re amazed at the tiny size and weight of the DelFly2, check out the DelFly micro, video after the break, that weighs 3 grams. Remember when we thought 17 grams was small for an ornithopter?

All processing for the DelFly2 is done at a base station and transmitted to the flying bot to keep the weight down. The team also had to create their own brushless motor that runs at 60% efficiency and weighs only 1.6 grams. The 130mAh battery can sustain 15 minutes of horizontal flight or 8 minutes of hovering.

First hovering ornithopter NAV

DARPA has awarded an extension to AeroVironment for their work on the Nano Air Vehicle project. The prototype seen above, called Mercury, is an ornithopter which means it flaps it’s wings. It is the first to show controlled hovering. Look closely, there’s no rudder or tail. Mercury uses the two wings for both lift and control. Ornithopters themselves aren’t new, we’ve even covered them before. Usually they use the flapping wings for propulson and a tail to steer as they travel like an airplane. We would really love to see some detail shots of Mercury.
