Scrub nurse | |||||||||||||||||
I have recently seen a news item about a robot scrub nurse called Penelope which supplies surgical tools to the surgeon during an operation. At present the unit can recognize 12 tools and perhaps it can be made to recognize twice that many. It seems it uses some sort of visual recognition to accomplish this. It seems to me that the range of recognition could be increased extensively by using RFID chips although I offer this idea out of almost total ignorance of the problems involved.

This may be a case where simpler is better. Put UPC barcodes on the things and existing technology will recognize more things than the hospital could buy.
Did some reporter actually write this up and marvel that the robot could recognize 12 tools? Maybe the next step is to make a robot to write news copy.
Take a look at http://www.plyojump.com/hrp.html. If they can dance, writing news copy can't be that far off.
Automatic order-picking machines (not really smart enough to call them robots) already use bar codes.It's just a matter of making the machines a bit smaller, and as far as I know they may already be in use.
Great, let's pay hundreds of thousands of dollars for a robot that can only understand basic commands so that we don't have to hire a nurse. They don't need jobs anyway, I suppose.
