Autobots are prim based human characters aimed to aid roleplay or entertainment sims, or for assistance in shops and so on. This carpet has a selection of church based characters it can rez, including priests, choir boys and nuns in various outfits.
Temp rez ones use the temporary prim facility in SL to allow large arrays of autobots to be rezzed without counting to your prim limit. By clicking on the carpets and selecting "On/Off" on the menu you can see arrays of maids, ladies, nuns and choir boys. You can then use the menu to customise each display. There is a limited animation built into these bots but obviously they cannot walk around like the autobots using normal prims.
Each bot is re-rezzed every minute only when someone is close by so whilst it is a bit of a cheat it is not done when there is nobody present. I have made them rez only when someone is within 64m of them which seems to work well. If you find you need this made a little higher please just ask.
There is a limit on the number of temp prez prims present at any time and if you try to rez too many bots at a time you will see the first ones disappearing as the later ones are rezzed.
The carpet itself can be made invisible once you have the item fully set up. Just click the ground around the maids to find it again.
Note that some sims ban the use of temp rezzers in which case obviously you should not use these products. Temp rezzed prims are also subject to occasional flicker and other visual artifacts so I suggest you play with them at my shop before purchase as unlike most of my other products these are no-transfer so as to allow the multiple copies of the bots to be rezzed.
