Who's responsible if your child has a bad reaction to the vaccine and dies or is permanently disabled?
Who's responsible if your child has a isn't vaccinated and gets: Diphtheria,Measles,Pertussis,pneumococcus,Polio,Tetanus, or Typhoid Fever and dies or is permanently disabled? Or better yet, Who's responsible if your child has a isn't vaccinated and gets: Diphtheria,Measles,Pertussis,pneumococcus,Polio,Tetanus, or Typhoid Fever and transmits it to a kid who or anyone who for medical reasons could get the vaccine and then they die or are permanently disabled? Being selfish is rarely good for society.
If you're going to drill any decent depth you'll have to put together a manned mission with a bunch of roughneck drilling rig workers. They're the only ones that can operate drilling equipment. It can't possibly be taught to other astronauts, and most certainly not some dumb robot.
Never mind the facts... where Apollo astronauts operated drills during the lunar landing. Or where, on a daily basis, pretty much ordinary joe sixpacks drill (water) wells to much deeper depths. Or that we have drills in rock quarries and mines that drill holes to considerable depths with minimal human intervention. Etc... etc... Thus there is no a priori reason to assume that it can't be taught to a "dumb robot", especially one that can so easily be backed up by teleoperation from Earth.
