1. A device for navigation through a biological anatomy, the device having a longitudinal axis extending in a longitudinal direction, comprising:
a first cell configured to expand and contract in the longitudinal direction and to correspondingly expand and contract an overall length of the device, wherein the first cell comprises a first expandable bladder;
a second cell configured to expand and contract in the longitudinal direction and to correspondingly expand and contract the overall length of the device, wherein the second cell comprises a second expandable bladder;
a third cell configured to expand and contract in the longitudinal direction and to correspondingly expand and contract the overall length of the device, wherein the third cell comprises a third expandable bladder; and
a control coil comprising a plurality of fluid channels, a first of the plurality of fluid channels adapted to inflate the first cell, and a second of the plurality of fluid channels adapted to independently inflate the second cell with respect to the first cell, wherein the first of the plurality of channels of the control coil is positioned within an inflatable space of the first expandable bladder, an inflatable space of the second expandable bladder, and an inflatable space of the third expandable bladder.
