The encoder is a device used to encode data onto a Disk which is used to give an Armbot certain commands. These commands allow the armbot to preform all of its needed tasks to be used on the assembly line. To view/modify a disk, first you must put a disk in the empty disk slot. Once you do that, if it has any commands on it already, it will list them in order they are processed by the Armbot. To add a command to the list, simply type in the command you want (listed above), and then click the plus sign. To remove a command, click on the command in the list so that it is highlighted, and then click the minus button. An Armbot will process the commands in the same order that they are added so be sure to have commands in the right order.
