Claim 5:
6. A lift device system comprising:
a lift device including
two vertical extendible tower members supporting a horizontal extendible transverse member further including
a horizontal extension assembly configured to extend and retract the horizontal extendible transverse member in a horizontal direction perpendicular to a vertical direction,
a traveler carriage configured to move in the horizontal direction upon the horizontal extension assembly between the two vertical extendible tower members,
the horizontal extension assembly further including
a first pair of telescopic slides attached to a left horizontal end structure and the traveler carriage, the first pair of telescopic slides defining a first plane being substantially diagonal to a longitudinal axis of the traveler carriage; and
a second pair of telescopic slides attached to a right horizontal end structure, the second pair of telescopic slides defining a second plane being substantially diagonal to the longitudinal axis of the traveler carriage and substantially orthogonal to the first plane, and

an omnidirectional wheel assembly configured to translate and rotate the lift device, and
a payload lifting device configured to raise and lower a payload with respect to the horizontal extendible transverse member and translate the payload in a horizontal direction between the two vertical extendible tower members;

a navigation control system configured to provide navigation control to the lift device when the omnidirectional wheel assembly is operating;
an extension control system configured to provide extension control to the two vertical extendible tower members and the horizontal extendible transverse member; and
a user-interface system configured to receive input from and provide feedback to an operator.
