Boy, this sounds pleasant. Researchers in Japan have developed a Minibot that enters your body via an incision. It's then controlled from the outside while it performs surgery on you. It has forceps to take tissue samples, can deliver medicine, and take pictures. Most previous mini robots designed for your insides could only take pictures; this is the first to actually be proactive once inside.
So what do you think? Would you rather have a doc slicing and dicing from the outside in, or would you be OK having a tiny robot swimming around your insides doing all the work instead? I can't really imagine the feeling of having a robot inside me, but I guess in the long run it would be better to have the most minimally invasive surgery possible.
