these so far because the question of state estimation in this in this scenarios is a lot harder but that's pretty cool that like by just spinning really fast you're able to stay hovering with three rotors and in fact what we did was sure that we could again in simulation actually follow somebody and avoid obstacles while just having three propellers and spinning like a like a madman so I don't think anyone's shown that before okay these are slides from cvpr it's a vision conference so I'm gonna skip those I wouldn't say that in fact I already
