Pop-up dragonfly robot could be the future of business cards

Engineers trying to be memorable at a job interview would be wise to pull one of these pop-up robots out of a wallet. This marvel of engineering uses a laminate construction technique to build a robot as a pop-up assembly. You can see the base used during the process, it’s a hexagon that serves as a scaffolding during the laminating process, and includes mechanical linkages that facilitate assembly.

The design calls for multiple layers of materials to be laser-cut to exacting specifications. Once all parts are completed, they are stacked using rods to align them, then fused together. One more trip through the laser cutter finishes the milling and the machine is ready for assembly. But with parts this small, you’ll want a solid method for putting everything together. The linkages we mentioned before allow for this when two parts of the scaffolding are separated. The only thing that makes this impossible as a business card is the need for a trip through the solder bath to cement the pieces in place. But perhaps some type of clasping mechanism could remove this need in the future.

Don’t miss the video after the break that explains the entire process. You’ll even get to see the little guy flap his wings. That’s all that it does for now, there isn’t any steering mechanism available as of yet.

The CIA’s amazing bots

When you have a virtually unlimited budget, you can pull off some amazing things. This has become most evident recently as the CIA has been showing off some of its old tech. That dragonfly you see above is near life-size and actually flies. They hired a watch maker to build a tiny internal combustion engine to run it. That alone is pretty amazing, but this thing was actually flying in the 70’s. Upon further inspection of the wings, we actually have no idea how this sucker is supposed to fly. Despite our skeptical viewpoint, you can see a tiny clip of it flying after the break.  You can also catch a video of “charlie” the robot catfish.
