Abstract
A sensor-based item transport system, and a method therefore are described. The system includes, for example, a cart station, within a restricted area including a plurality of automated drive. A light curtain is adjacent to the cart station. A first sensor and a second sensor are spaced apart from the first sensor within the cart station. A first mode associated with the light curtain is maintained causing an alarm system associated with the light curtain to remain armed. The first mode is caused to change to a second mode associated with the light curtain, the second mode causing the alarm system to be muted, based at least in part on the identity of the cart. The identity is determined based at least in part on one or more signals received from the first sensor and the second sensor.
