  • Method and apparatus for controlling surface traversing device
    Patent number: 4074814
    Abstract: A method and apparatus are provided for controlling the movement of a surface traversing apparatus across a member which has an ordered array of openings in it's surface. Move control routines are provided, each of which instruct the traversing apparatus to move incrementally over the surface of the member by disengaging, incrementally moving, and re-engaging one of two stepping arms. Each routine operates to advance the apparatus an increment in one of a number of directions. Some of the routines move the apparatus parallel to lines or rows of openings. Others move the apparatus diagonally. Each routine senses the relative positioning of the two stepping arms to establish the sequence of operations and returns the stepping arm to its former position if it is unable to complete a step.
