Robots really are pervading our everyday lives. Earlier they were no more than show pieces. These days, we even find them by the side of our sick beds. If you were of the opinion that robots have no heart, this video-conferencing robot at Baltimore should change your mind.

This particular robot comes in handy whenever the doctor is away. The video-conferencing facility allows the patient to converse with the doc to solve immediate medical problems. I never would have thought that one could work as a doc from afar. But these days, anything is possible.
