Hoverbot (does not actually fly)

This video describes a small project by Brian Chan and Theresa Guo at MIT. It is a machine that flaps its wings and indicates the amount of lift generated. The data will be useful to determine how the force varies with a changing wing stroke angle, and thus help us design better flying machines.

Sorry to correct you, but the hummingbird actually moves its wings in a ∞ (infinity sign) motion.

[chosetec]

I know, the horizontal motion is the first-order approximation that we were most interested in.

@smartninja2 i dont think so, because its a cicle, for every move upward ther goes one downward, also they used the same bot for both experiments so theres no advantage, also the experiment isnt about the power of the bot, but the efficiency

[smartninja2]

Doesn't the the tilting of the bot as it rises have any affect on the lift generated?

That mechanical mechanism looks sexy.

I thought it was well understood that small wings treat at high cycle rates, "see" air as a much more viscous fluid than we are used to in classic aerodynamics.

Basically, don't these wing structures generate counter vortexes and use them for motive force?

Knowing this, I don't think one can make any significant conclusions about dragonfly efficiency versus humming birds.

IMHO

I'm amazed.

wow awesome!

nice animations and mechanisms brian

Bravo... :D
