A system for deploying a device includes an elongated flexible instrument (108) and a shape sensing system (104) coupled to the flexible instrument. A hub (106) includes a shape profile configured to receive and maintain the flexible instrument with the shape sensing system therein. The shape profile includes a shape to track a position or a rotation of the hub relative to a reference position using the shape sensing system. The hub is configured to be coupled to a deployable device (102) such that a change in the position or rotation of the hub indicates a corresponding change in the deployable device.
