So, that super far fetched movie is really not that far fetched after all.

Magnetic "Micro-robots"

These magnetic particles are manipulated by magnetic fields to open and close their pincers and pick up a glass bead to move it around. The particles lie at the interface between layers of oil and water. A magnetic field perpendicular to the interface causes the particles to form the clumps/"micro-robots" and a magnetic field parallel to the interface causes them to swim. So the next step is obviously to filter different beads from a mixed bag of them. And then, world domination.

Hamburger Robot

I had an interesting thought today: if fast food is supposed to be fast, why are humans making it? Couldn't a robot do it faster and more precisely? Could there McDonald's vending machines where I can customize my order? Then I could isolate myself further and not have to talk to anyone but still get my freshly thawed Mickey D's.
Well, someone else, nango17 on youtube, had the same thought in 2009, but he/she actually used Lego mindstorms to create a hamburger robot. It's kinda slow and imprecise, but it's still exactly what I was looking for.
