Wobbly and shaky hands is one thing.. focus, endurance, precision and also consistency while operating is another.. we're not talking about 10 minutes operation.. it took hours.. in that time, talent is very important as if a person who have wobbly and/or shaky hands will have their condition amplified through time.. At first glance it will help for some not-so-talented person become a surgeon.. with those anti-wobbly feature taking some movement for extra reference.. but.. that will just make talented surgeon doing more movement per operation compared when using similar tools without the anti-wobbly feature.. unless the feature can be turn on and off at will.. that might make a difference..
I was a software engineer on the first CE approved surgical robot 25 years ago. So this isn't particularly new. They are getting better and cheaper (ours was more than $1M in 1999 when $1M was real money).
