On my surgery rotation I scrubbed in on a few Da Vinci robotic surgeries. They were amazing, and I even got to sit in the counsel on one. Robotic and telerobotic surgery is going to be a very innovative field, however it is highly dependent on having a well trained physician behind the controls.
Robotic surgery will not replace surgeons, it will however help them to preform less invasive, more accurate surgeries. Primarily the Da vinci robot allows for seven degrees of freedom in movement with its robotic arms. This allows the surgoen to preform complex laproscopic tasks that previoulsy required an open procedure. Conventional laproscopic surgery is limited by the "fulcrum effect" which means moving the tool "up" produces a movement of the insturment "down." (Its like playstation with the axis inverted) While this is a bit oversimplified, it is one of the drawbacks of laproscopic surgery.
Robotic surgery eliminates this "fulcrum effect." Also the Da Vinci machine counsel enables a
3-D mage to be shown to the user which allows for depth perception. In any case its a super cool field
