iRobot Corporation (IRBT)

Their heathcare bot has recently obtained the coveted FDA approval necessary to provide for patient monitoriing, collection and transmission of patient sensitive data. As of today, it is only servicing hospitals. http://www.intouchhealth.com/company/press-releases/07-24-2012/
However, I am confident that the next logical step in the product evolution will to develop a version of the AVA for home use. Given the growing number of aging babyboomers coupled with the near broke medicare system I forsee a scenario where the feds will be forced to act aggressivly to reduce elder care and nusrsing home costs.
Finally, when you consider IRBT's lobbing capability, I think they're perfectly poised to obtain the necessary Medicare approvals that will be needed to control the market.

Of course, this is just my misguided two cents and you get what you pay for.
