Beetle walker

Beetle troopers were built by the Trade Federation before the outbreak of the Clone Wars. They were used as mounts for battle droids, and were deployed on worlds with terrain that was difficult for battle droids to traverse on foot. Production of beetle droids halted after the Battle of Geonosis, when the CIS began to manufacture more efficient means of transportation for battle droids. Beetle droids could fend for themselves to a certain extent, and even go into battle alone, but to really be effective, one would need a battle droid to mount it and establish a data link. This way, the battle droid would be able to decide the actions of the beetle droid.
