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.
