Robot Diagnostic Doctors to Lower Medical Costs for the Billions?

The world shortage of physicians to accurately treat disease may be logical filled one day by low-cost robotic diagnostic doctors with memory banks of every disease and symptom known to man. With terabyte SD cards on the horizon building 1000 terabyte robot memory for low cost can be foreseen. The field of manufacturing robotic physicians to diagnose illness with a built in synthetic tool kit of imaging and chemical analysis devices and software for interpretation is logical as well.
One would think that the National Institute of Health could provide a project paradigm for development of the ideal robotic doctor to lead capitalism to radically lower the cost of quality medical care for the billions.  Obviously one might worry about making the beast’s image and consider planting a self-destruct circuit in the robotic doctor if it goes to the dark side of the force-yet I think that the prophesied Evil Leader would find some other vehicle for its rep to appear in. So, returning to the cheaper medical care project…
Dr. Robots able to walk the walk and talk the talk might be able to be trained to illegibly scrawl prescriptions too. Dr. Bots would have a good patient communication lexicon and deductive language reasoning capability to ask and understand any foreseeable human response to probing questions such as does it hurt?
There may be a primary difference between diagnostic Dr. Bots and Dr. Fix–all bots. Obviously some entrepreneurs would seek to package diagnostic and treatment bots together one day in competition one-upsmanship. Some surgeries could be performed by programmable robotic platforms with built in surgical procedures data banks  in field clinics while others might need to be established in permanent treatment facilities although modularizing Dr. Bots Surgeons on hovercraft for location to roadless areas might be useful. They should all have solar recharging capability for powering up as well as fuel cells.
While it is true that human volunteer networks to examine breasts are easy to innovate, checking human health through vaginal or anal data-ports is more of a problem. One can imagine robotic probes with smaller, non-invasive diagnostic imaging tools able to more accurately interpret infrared imaging and perform chemical and biological analysis from a comprehensively broad spectrum of the human eco-complex. A Dr. Bot alien probe should be able to provide one’s genetic ancestry as routinely as making a blood survey.
