Local Motors had one of their most successful co-creation challenges in the past 40 days with the launch of ACDC (Airbus Cargo Drone Challenge). The challenge started with mostly otherworldly and crazy designs from Local Motors' base automotive design community, but later evolved into a truly collaborative effort between designers and engineers with the shared vision of building the next gen unmanned cargo vehicle.
Looking at the submissions, you will see a nice blend of concepts ranging from pure aircraft design to more user and application focused proposals. You can actually be a part of the selection process by going to the LM platform between June 6th and 16th to vote for your favorite concept!
Here a few of my favorite, non-derivative, original submissions:
Starting with a friendly, approachable, multi-purpose Cargo Drone, POD
And finally Airbus Engineers' dream design :) it does remind me of a boring but functional chameleon!
I bet 50K, of my currency of choice, this last one or its equally German sibling is going to win the grand prize :) Let's see! It must have been a fun journey for all the participants and organizers.
P.S.: feel free to build a prototype of any of these designs or others on the challenge page, LM has a very community friendly license for this purpose as long as you don't use the designs commercially.
