A feedback control system for use in connection with automatic material-handling apparatus for controlling the acceleration and/or deceleration curve of a movable material-handling assembly, as for example, an automatic or semiautomatic robot used in conjunction with delivering and retrieving material from a storage warehouse, wherein the distance from a fixed or variably selectable point is sensed and utilized to generate a speed curve for controlling the incremental variation in speed of the material-handling apparatus up to a preselected maximum speed or down to zero speed.
