With baby boomers making the transition into the 65-and-older crowd, researchers at the University of Massachusetts Amherst have developed a robot that can help in case of a medical emergency. What can this droid do - use a stethoscope, call for an ambulance, and facilitate a video call with a doctor allowing them to see and communicate with the victim/owner. It can also remind people to take their medication, pick up packages and do some cleaning. Wow! The first uBOT-5 took about $65,000 to develop but, if mass-marketed, the bot could cost as low as a few thousand dollars.
