Stanford Autonomous Helicopter - Autorotation landing

The Stanford Autonomous Helicopter performing power-off descent and landing under computer control.

Helicopters can glide and land in a flight mode known as "autorotation" without engine power. In this mode, the helicopter's descent keeps the rotor blades spinning, allowing the computer to maintain control. A carefully timed flare just before impact expends the blades' rotational energy to slow the helicopter before touchdown.

Does anyone know what the devise(it was used to slow rocket down right before impact) is called? A precise, intelligent answer would be  greatly appreciated it

Was the pitch reversal done manually or automatically with on board stuff?

[videocruzer]

does the system respond to the lack of power and then performs the auto?

or is the heli already in an auto when you let the flight system finish the auto?

pretty cool either way

1:30 looked the best for me ^_^

What kind of sensors does the helicopter have in order to know how far is it from the floor??? IR sensors???

are you using an accelerometer or something like that to keep the helicopter parallel to the earth????

Very cool Man i would take a step back if someone brought a robotic 90 to our field lol
