Abstract
An autonomous mobile device (AMD) includes a telescoping mast with sensors on top that are connected to a cable running through the mast. An inner section of the mast includes a bobbin that secures cables. The bobbin has a shaft and features that guide cables to helically wind around the shaft. The bobbin reduces stress on the cable as the mast moves. The mast is lifted by a rack that includes a portion with teeth and a portion without. The portion with teeth is driven by a motor. The portion without teeth connects the rack to a spool. The toothless section reduces stress on the toothed portion of the rack as it spools or unspools. The AMD includes a hinge to tilt a display. To securely position the hinge on a shaft, the shaft is spun after assembly so that a push nut cuts a retention groove in the shaft.
