1. An alignment and task indication system comprising:
a conveyor cart including a first sensing element attached at a first height along the conveyor cart and a second sensing element attached at a second height along the conveyor cart, the second height being different from the first height;
a first conveyor including a first alignment sensor, the first alignment sensor being attached to the first conveyor at a height that corresponds to the first height, whereby alignment of the first alignment sensor with the first sensing element causes a first alignment signal to be transmitted to a controller, the first alignment signal confirming alignment between the conveyor cart and the first conveyor;
a second conveyor including a second alignment sensor, the second alignment sensor being attached to the second conveyor at a height that corresponds to the second height, whereby alignment of the second alignment sensor with the second sensing element causes a second alignment signal to be transmitted to the controller, the second alignment signal confirming alignment between the conveyor cart and the second conveyor;
wherein the controller determines, upon receiving the first alignment signal, that the first conveyor is an unloading location; and
wherein the controller determines, upon receiving the second alignment signal, that the second conveyor is a loading location.
