A telepresence robot is a remote-controlled, wheeled device that has wireless internet connectivity. Typically, the robot uses a tablet to provide video and audio capabilities.
Telepresence robots are commonly used to stand in for tour guides, night watchmen, factory inspectors and healthcare consultants. In a distance education class, a telepresence robot can move around the room and interact face-to-face with individual students, just as an on-premises instructor might. In business, a telepresence robot can be used to help an employee whose disability or location prevents him from traveling still have a physical presence in the office.
