You access the inventory of another robot via its external view.<br /> <br /> The reason for this distinction is to separate the two inventory spaces: the main inventory and the tool belt inventory. Internally, the robot selects slots only in its inventory space, and not its toolbelt. It can `equip` or unequip items from its toolbelt. However, externally, an observer interacts with a single inventory that includes both the toolbelt as well as the main inventory.<br /> <br /> = ==== Internal Robot Slot Alignment =<br /> <br /> The Robot&#039;s GUI displays the slots of a robot aligned from top-left to bottom-right. So for example the slot at index 1 is displayed in the top-left corner, the slot at index 2 is the next to the right and the first slot on the 2nd row is index 5.<br /> <br /> [[File:robot_slotalign.png|robot_slotalign.png]]<br /> <br /> These are the slot indexes a robot uses on it self (for its own main inventory, an interview view).<br /> <br /> How many slots a robot has available depends on it&#039;s setup. If a slot is specified in a function that exceeds the amount of slots a robot has available an error is thrown.<br /> <br /> The robot can `select`, `place`, `drop`, `compare` (etc) items from its main inventory using these slot indexes as they represent the internal perspective of its inventory.<br /> <br /> = ==== External View of a Robot Inventory =<br /> <br /> Slot indexes of a robot&#039;s inventory to an outside observer will be offset by 4. To an outside observer, slots 1 through 4 refer to slots in the robot toolbelt. The first slot of the main inventory is slot 1 from inside the robot (internal view), but is thus slot 5 to an outside observer. Yes, this can be confusing at first. This design choice was made so that, to an outside observer, [slot 1] always indicated the first toolbelt slot regardless of the robot inventory size, and [slot 5] was always the first main inventory slot.<br /> <br /> The robot inventory, again to an external observer, is sided inventory. The robot will not share all its inventory to all sides. Slot indexes &lt;span class=&quot;underline&quot;&gt;do not&lt;/span&gt; change to these different sides. Slot 1, therefore, always refers to the first toolbelt slot, even when inaccessible to a side.<br /> <br /> &#039;&#039; From its left side it share nothing. &#039;&#039; From its right side it shares only its toolbelt slots (1-5) * From all other sides it shares only its main inventory slots (5-n)<br /> </div>
