Scavenger droid

Scavenger Droids, often called scavs, were small automated droids, generally operating in gangs, which were deployed at accident sites to scavenge for usable parts.

Histoy
The Trade Federation employed a large number of these droids to search through the remains of their battle droids after battles, to seek out any parts which could be used again in new droids, therefore cutting costs. They were also used by salvagers etc, to aid their exploits.

Another variant, used by Trandoshan mercenaries and slavers, was built to attach to a clone trooper's helmet, drill through the visor, and eliminate the trooper then carry them away. This type was also equipped with a beam weapon capable of draining the personal shields used by clone commandos. They could also attach themselves to walls and cut through cables, waiting silently for their prey and then attacking. Afterwards, the droids would pick up the bodies and carry them to dump sites.
