"I am in no position to comment on the feasibility of this particular design, but just wanted to point out that this company is legit and are the ones who made the quad that won the endurance contest by staying aloft for (if my memory serves me…"

"Do they have a fire department version with a foam dispenser :-)"

"That is sick looking. But the day police departments buy drones to patrol the streets is the same day I am buying a shotgun. "

"Another Solidworks video about how can we render useless but good look things.Did you see the GPS disc insite? I guess the designer thinking the drone gps antennas looks like mapping gps rings. And this is why they need ring type GPS antenna and a…"

"Great video, but as everyone has said unpractical.  My favourite part was the "Anti-Collision" system that would probably drive itself through a tree.  "

"Good idea Gary, and they will also take crowd control to the next level driving around with 12 props running at knee height!"

"+1 on reminder about policy. On a less serious note... Teargas is completely unnecessary here. the sight of this flying shopping cart is enough to make anyone cry. I wouldn't get too excited about this particular "innovation".…"

"Tear-Gas? Really? I saqw tear-gas canister under that thing. Forgive me for perhaps being over-sensitive, but I live in the Bay Area where the cops have a tendency to shoot people in the face with tear-gas.  As UAVs get more police-friendly…"

"This introduces 12 points of failure. The shopping cart wheels look terrible under it."

"Magic and or alien technology, it will be big in the future trust me."

"But how do you even generate horizontal thrust to move when you're level (on the ground)?"

"Less power used to drive it between waypoints, then pop up take the shot land and drive to the next?"

"Why does it have wheels???"

"Will it pass ASTM F-38 muster and testing at the proposed DHS stations?"

"it does what most concept are supposed to do. get attention to the company who did it."

"As usual concept animations make everything look great. But in the real world, 12 motors and coaxial is going to be very inefficient. Remember each motor/propeller you add increases the inefficiency, and working in the downdraft of another propeller…"
