Meet the Double Robotics Telepresence Robot: a robot for tablet that facilitates telecommuting. You can place your iPad in the robotic base and control it from your iOS device or computer. It does not matter where you are in the world. This robot gives you the freedom to round around anywhere and attend meetings from a remote location.
This robot lets you video chat with others without having your coworkers set up a video conference. The internal battery lasts for up to 8 hours. This is compatible with all iPads with a camera. Not cheap but quite useful to businesses.
