The quad these guys are using is a Crazyflie. Small, mostly prebuilt, targeted at researchers. It has a few "addons" like optical flow sensors and external position trackers that let you extract ground truth attitude/position, which is helpful for research like this. Not really "off-the-shelf," but it's a good thing to get if you care more about the controls, learning, trying new algorithms stuff more than sourcing parts, getting RC receiver/tx, sizing motors, that kind of thing. https://www.bitcraze.io/products/crazyflie-2-1/ https://www.bitcraze.io/products/crazyflie-2-1/
