For those curious, I found (easily) a couple of URLs with more info on robotic assisted surgery:

Gee, LR, it seems like complicated surgery is getting more and more like taking the car in for engine problems. Need a valve job? No problem, drop it off in the am, back on the road in no time!
Glad to hear the procedure went well. We'll look for a post about your first ride out on the lake after you're back home.
