Pressed by an operator each time a robot is needed to pickup a load. Similar to "calling" an elevator.

A sensor can be used to send a signal to call the robot to come and pick up product. These sensors work similarly to when you walk up to a door and it automatically opens.

Based on the graphic displayed on the touch screen, software knows where to send robot for pickup and delivery. 

If you already have a machine, a standard robot, or something that has any type of controller or computer in it, then the "computer" can be programmed to automatically send signals to the robot.

This option is for facilities that already have an inventory system that keeps track of all parts or loads in a factory. This signal can be used to call for the robot wherever or whenever needed.
