And this isn't just a needle dream. Panasonic has once again started selling its Hospi hospital robots, after first developing them a decade ago. At that time, they didn't catch on, and the company only sold a total of two robots, IEEE Spectrum reported. But now, with health care costs rising and improvements in robot tech, the time is right for Hospi. There are now five Hospi's operating in Matsushita Memorial Hospital in Moriguchi, Japan, where they've reduced delivery times by over 30 percent. They each cost US $100,000, and getting the infrastructure to run them costs several hundred thousand more. But once they are up and running there are very low maintenance costs.
