Meet Bob-E: a robot that lets you look around and control it using a VR headset. It has cameras that can follow your head movements at a speed of 0.91 seconds / 60 degrees. They are only 65mm apart.
With this robot, you can carry a payload of 5kg, interact with others, enjoy a presentation, and do a whole lot more. Bob-E creates its own WiFi network and uses the motion sensors of your mobile phone for head tracking. You can control its movement with a joystick. More information is available here.
