It doesn’t have four rotors, but this advanced-glider is every bit as impressive as the most complicated of quadrotor offerings. It’s the first glider that can successfully perch on your arm. We can’t help but think back to the owl in the original Clash of the Titans movie.
The team at the Aerospace Robotics and Control Lab of the University of Illinois at Urbana-Champaign is happy to show off the test flights they’ve been conducting. We’ve embedded two of them after the break which show the unit landing on this person’s arm, and on the seat of a chair. The image above shows a montage of several frames from the flight, and gives us a pretty good look at the articulated wings. You can seen them both bent in the middle of the flight to zero in on the landing zone. In addition to this there are flaps on the trailing edge of the wings and tail. The flight path is a bit wandering since the glider has no vertical tail to stabilize it.
Now if they can make it harvest power from overhead electrical lines they’ve got a spy-bird which can be dropped from a plane (or from a drone).

When you start to think about the cellphone waste our society produces it can be quite daunting. How many cell phones have you had in recent years? Now multiply that by five billion cellphone subscribers. [Anthony Goh] and [Neil Mendoza] found something to do with a very minuscule portion of those left-overs; building interactive birds out of the old parts. You’ll have to check out their accomplishments in the video after the break as the image above doesn’t do them justice. Interactivity for the exhibit is provided by an Arduino, which communicates with one working phone via a serial connection. The phone can still make and receive calls, and controls parts from other, less functional cellphones. They can call each other, or receive calls from the audience.
Yes, there is art in garbage. But there’s also a lot of hacks waiting to happen. Take a look at the Nokia cellphone LCD feature and then start scavenging.

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.

[Matt Meerian] introduced us to his kludge of cardboard, tape, mirrors, and electronics in the form of a clever non lethal robin trap. Whenever a pesky robin would enter the box, a sensor is triggered, the solenoid drops a lid, and the bird is contained (and we assume taken far away after that).
Of course the plan backfired; we wont spoil what happened, but you can click the link above to find out.

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.
