Abstract:
1. A mobile video teleconferencing apparatus comprising: (a) a base; (b) two wheels rotatably connected to the base in a statically unstable configuration; (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 statically unstable 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.
