Various embodiments are generally directed to positioning techniques to facilitate entry of a flexible elongate member (e.g., endoscopic accessory tool) into and/or through selected anatomies, such as by directing a set of positional controls based on feedback from a set of transducers to achieve or maintain a position within a body lumen, for instance. Some embodiments are particularly directed to a feedback loop for positioning or guiding a flexible elongate member into a target configuration for one or more of inspection, orientation, and/or facilitating access to body passageways. In one embodiment, for example, a device manager may include circuitry to operate at least one positional control in a set of positional controls based on data indicative of a current configuration of a flexible elongate member generated by a set of transducers.
