Chameleon Droid
this was the name given to the retooled Spelunker probe droids used by the Confederacy of Independent Systems to covertly lay mines and explosives during sabotage missions. Resembling four-legged spiders with cylindrical bodies, the chameleon droids was named for the sophisticated holographic array that could be generated around it, rendering the droid virtually invisible to most beings. This was not a cloaking device, but rather a way to project imagery that matched the chameleon droid's surroundings, making it appear that the droid wasn't actually there. Inside the cylindrical body as a small repulsorlift engine, used to help increase the droid's agility and speed by removing some weight from the legs. A turret-mounted laser cannon helped the chameleon droid defend itself if its presence was exposed.
