A payload exchange facilitating connector module, comprises: a) a structure secured to a payload b) a locking member operatively connected to said structure! c) a locking initiating element that is settable in force transmitting relation with said locking member! and d) two guiders configured to urge an interface element of two different external positioning components, respectively, to undergo linear and non-rotatable relative motion exclusively with respect to said structure, until said locking initiating element is set in force transmitting relation with said locking member to cause said locking member to become coupled with a dedicated element of a first of said positioning components, or following decoupling of said locking member from said dedicated element to facilitate payload exchange.
