Looks like a copter drone which happenes to have wheels and a controller that pushes it not "up in the air" but towards the ground or walls.
Which also means this thing will probably not be able to lift any significant payload up walls.
But it's an interesting way to evade airspace regulations against drones. Lookout for the first paparazzi shots taken from wall climbing drones lifting cameras up celebrity-houses ;-)
Something tells me that regulation of drones won't work as expected.
