Robotic plotter system

A robotic plotting system, comprising:

• a first surface adapted to produce a time-synchronized presentation output signal in response to a written image entered by a user at a first site;
• a network adapted to send said presentation output signal from said first site to a second site;
• a plotter transmitter module at said second site adapted to receive said presentation output signal and also adapted to transmit a combined input signal having a plurality of distinct frequencies which communicate a printhead coordinate input signal and a pen activation input signal in response to said received presentation output signal;
• and
• a plotter printhead at said second site having a receiver element adapted to receive said combined signal from said plotter transmitter module, a detection system having a plurality of bandwidth filters, for receiving said combined signal from said receiver element and for isolating said printhead coordinate signal and said pen activation signal through said plurality of bandwidth filters, a motorized drive system directed by said printhead coordinate signal through said receiver element for propelling said robotic plotter printhead across a recording medium in a controlled manner, and a pen tip activated by said pen activation signal through said receiver element for writing onto said recording medium.

A process, comprising the steps of:

• inputting a combined plotter signal to a remote plotter printhead having a pen tip, said combined plotter signal having a plurality of distinct frequencies which separately communicate X and Y location coordinate input signals and a pen activation input signal in response to said received presentation output signal;
• feeding said combined plotter signal through a plurality of filters to isolate said X and Y location component input signals and said pen activation input signal;
• independently processing said X and Y location component input signals and said pen activation input signal to selectively and simultaneously produce X and Y location component activation signals and a pen activation signal;
• selectively directing said remote plotter printhead across a recording medium in response to said independently processed X and Y location component activation signals;
• and
• selectively moving said pen tip into contact with or away from said recording medium in response to said independently processed pen activation signal.
