Really curious how that thing generates torque since it doesn't have asymmetric props.
edit: I'm dumb, it has gimbaled props. That makes OP's link much more impressive, since that thing doesn't require gimballing which is expensive.

- phreeza 9y agoyea there is another top level comment by gtirloni which links to a different example which does it without a gimbal, by applying a sinusoidal current with variable amplitude and phase to the motors. They have symmetric rotors though, so your question applies there! I wonder if maybe the rotors are in fact slightly asymmetric and just look symmetrical. edit: I got it, this is super neat: The blades are hinged at a 45 degree angle, but in opposite directions. See Figure 1 and 2 here http://www.modlabupenn.org/wp-content/uploads/paulos_an_underactuated_propeller_IROS_2013.pdf http://www.modlabupenn.org/wp-content/uploads/paulos_an_unde...
- hatsunearu 9y agoYeah, that still requires moving parts on the rotor. OPs design requires no additional moving parts. I like it.
