Remote users connect to this robot via a Mac or PC software app, then control the avatar via a remote control. Up to 20 people can download the accompanying app that's used to communicate with and pilot the VGo, but only one person can use the robot at any one time. Employing a 6-inch LCD, a camera, microphones and a video display, the 4-foot-tall VGo works well when interacting with both standing and sitting individuals. It also works wherever there's Wi-Fi or Verizon 4G LTE. Even better, VGO Communications claims the battery-powered VGo can last up to a full day on a single charge. The company designed its VGo for the healthcare and education industries, specifically pinpointing patient monitoring, off-site studying and remote visiting.
