1. A mobile video teleconferencing apparatus comprising:

  • (a) a base;

    (b) two wheels rotatably connected to the base;

    (c) a movement control subsystem mechanically rotating at least one of the plurality of wheels;

    (d) a video subsystem comprising a video camera;

    (e) a central processing unit, the central processing unit controlling the movement control subsystem, and accepting video data from the video camera;

    (f) a data link for communicating between the central processing unit and a remotely located computational device, the data link sending video data to the remotely located computational device, and receiving movement control data from the remotely located computational device;

    (g) a vertical support member, the top of the vertical support member supporting the video subsystem and the bottom of the vertical support member connected to the base; and

    (h) a dynamic stabilization subsystem, whereby the apparatus is kept substantially upright in the fore-aft plain through a control loop which senses the forces acting on the apparatus and drives the movement control subsystem.
