Edible robot surgeons will cure you from the inside out

Back in 1985, the best robotic surgeon we had was the PUMA 560, a manipulator arm just barely more advanced than Rocky Balboa's robo-butler. The PUMA was nevertheless revolutionary. It was the very first mechanical operator, progenitor to steady-handed robo-surgeons like of the DaVinci system. But in the near future, robots will no longer be cutting into us -- from the outside, at least. Even as the the current generation of robotic surgeons continues to shrink, with miniscule pincers and malleable toolsets capable of curling their way through our innards, the medical community is working to develop robotic surgical devices capable of operating autonomously, or at least remotely.
