Re: Underactuated Rotor for Simple Micro Air Vehicles
#2This thing is so nimble in the air yet has a fraction of the complexity of a regular helicopter. I wonder if this method will scale up to "full size"?
Re: Underactuated Rotor for Simple Micro Air Vehicles
#3I wonder if this will cause some parts of the motor to heat up more; since the blade is 1:1 rotations with the motor then driving more torque (power) during certain phases of the cycle will put more watts on certain coils.
It's a cool idea. Human size helicopters would love to avoid all that blade-pitch complexity. :)

#4The whole thing looks great and all. But I specially liked their last sentence that said "for civilian needs".

#5This is so clever! Turning mechanical control problems into informational control problems is critical to the ubiquity of micro air vehicles.

#6Very clever! I hadn't fully understood the mechanical complexities involved in a standard single-rotor helicopter. I just thought that they were hard to fly manually (which made me very confused to see all the computer-controlled quadrocopters - why didn't they use just one rotor?)

Couldn't that be addressed (if a large enough effect to be a problem) by just having the body of the vehicle spin at a low rate, like less that 1Hz. With appropriate sensors this wouldn't be a problem[1]. More to the point, there shouldn't be any need for sustained constant "cyclic" input anyway, in normal maneuvering.
[1] an axially-symmetric imaging system could compensate easily, e.g. a panoramic system.
