This machine, said to be, a "currently starting" project, is a (much nicer looking) Rep-Rap / MakerBot but for food creation. The brainchild of MIT visionaries Marcelo Coelho and Amit Zoran, the tool appears to use the same fused layer deposition model that many of the various 3D prototypers out there use but it has a material changer which, other than in the multicolor Z-Corp printers, I believe is unique.
"Cornucopia's cooking process starts with an array of food canisters, which refrigerate and store a user's favorite ingredients. These are piped into a mixer and extruder head that can accurately deposit elaborate combinations of food."
I've been waiting for robots to make my food for a long time. Hopefully it will taste better than anything we could possibly imagine and not like extruded food paste leftover from the Mercury project. As William Gibson said, "the future is already here. It's just not very evenly distributed."
