Abstract:
A plotting apparatus is disclosed for use in an automatic plotting system including a first pivoted arm carried by a first pivoted support and a second pivoted arm adapted for carrying an instrument head mounted on a second pivoted support carried adjacent a free-end of said first arm. A power operated drive pivots the first and second arms through angles in response to the input of a pair of angular coordinate signals providing a high degree of resolution between points in the plotting operation.
