ABSTRACT:
A robotic plotting system 10 is provided, in which a robotic plotter 18 having a printhead 18 is placed on a substantially flat horizontal surface 23, upon a recording medium 22, and is directed across the medium 22 by ranging signals 16 transmitted to the printhead 18 from the periphery of the recording medium 22. In one embodiment, the robotic printhead 18 includes a motorized drive mechanism 26, 28 that propels it across the surface of the recording medium 22 in a controlled manner, for example using microwave control signals 16. Thus, a user can place a piece of paper 22 of any size on a flat surface 23 such as a table or floor, and the printhead 18 is propelled across the surface 23 and is directed by signals 16 beamed between the printhead 18 and a control mechanism 14. In this manner, a large-surface-area plotting system 10 is provided in the form of a small hand-held device.
