Abstract
The invention provides for an inexpensive plotter/digitizer which can be attached to existing drafting boards of varying sizes. The device uses flexible links, such as cables. Length, speed, and tension of the links is monitored by sensors. The speed, accuracy, and line quality of plotting are improved by reduction of the weight of moving components and mechanical simplification of the drive mechanism. Trajectory Control for more than two link drives for prescribed two-dimensional motion is described together with Stationary Control which maintains required tension on cables. Microprocessor controlled, multimode operation of individual drives is indicated.
