A single cell of this distributed flight system can spin its propeller but it comes at the cost of the chassis flying out of control. To realize any type of stable flight it must seek a partnership with other cells. The more astute reader will be wondering how it can autonomously pair if incapable of controlled solo flight? The designers of the project thought of that, and gave each frame a way to propel itself on the ground.
Along the bottom rails of each cage there are several small knobby wheels. These seem to function similar to omniwheels since they are not aligned in parallel to each other. Pairing is accomplished mechanically by magnets, also helping to align the pogo-pins which connect the cells electronically.
Flight tests are shown in the video below. The array can be oriented in symmetrical or asymmetrical patterns and still work just fine. If they have 3D camera feedback they can hold position and navigate quite accurately. But this can also be piloted by remote control in the absence of such a feedback system.
