The VGo telepresence robot was a favorite of the booth. The robot acts as a proxy for someone who can't physically be somewhere, whether it be because of distance or a medical reason. It has a monitor to show the face of the person, as well as a camera and microphone so that person can see and hear everything VGo can. That person can control where the robot can go. VGo has been out with Wi-Fi for a year, but an LTE version was announced at the show.
