Abstract
A system includes a rack with rows for storing drill pipe, and a moveable structure having a control support coupled to an upper portion and a lifting device coupled to a lower portion. The moveable structure travels along a guide for positioning adjacent any of the rows. The control support includes a pivoting actuator, a rotating actuator, an extension arm having a drill pipe capture actuator, and an extension actuator. The lifting device includes a lifting actuator that raises a stack of drill pipe. The system further includes a controller that interprets a control support state including actuator positions and a position index value, and records a position description including the control support state corresponding to the position index value. The controller interprets a position request signal and provides actuator control signals in response to the position request signal and the position description.
