The method and apparatus regulates the position of an arm of a wellbore tool allowing bidirectional movement of the tool in the wellbore. The presented method and apparatus allows predicting and therefore acting in advance on the mechanism of an oilfield tool inside a wellbore, enhancing bidirectional movement and operation of the tool inside a wellbore environment typically for logging the well. The present method and apparatus provides for regulation or control between different sensing parts resulting in protective and corrective actions to prevent damage and provide optimal sensing contact with the wellbore or placement of the sensors in a desired proximity to the wellbore wall..
