BT-16 perimeter droid
- "You seen that new VT-16?"
"Yeah, some of the other guys were telling me about it. They say it's… it's quite a thing to see…" - ―KE-829 and his partner aboard the first Death Star
The BT-16 perimeter droid, also known as the VT-16, was a bulbous, spider-like droid manufactured by Arakyd Industries.
Characteristics

The BT-16 came equipped with highly sensitive sensor packages, including a Fabritech seismic reader and a Carbanti motion detector. It was armed with a Taim & Bak repeating blaster cannon. The droid also featured a TranLang I Communication module and a vocabulator, though it was only able to speak droid languages.
History
These droids were used by the Galactic Republic and later the Galactic Empire.
Early production runs reused the chassis of the TS-Arach series Pest Control Droid before the six-legged design was introduced. The B'omarr Monks used these droids to carry brains of those who had achieved "enlightenment" and for this they were sometimes called Brain walkers.[4] The droids were occasionally equipped with vocoders, and lived in Jabba Desilijic Tiure's Palace until his death. The walkers generally went unarmed while carrying a brain, and had trouble doing anything beside walking.
A used BT-16 perimeter security droid was utilized by the Katarn family of farmers on Sulon, a satellite of Sullust. The droid, programmed to hunt vermin, possessed a faulty sensor package which caused it to fire upon and kill Patricia Katarn.[5]
Behind the scenes
In Cynabar's Fantastic Technology: Droids, the picture of the BT-16 is a mirrored version of the TS-Arach series Pest Control Droid image from the same guide. Contrary to the idea that the 'brain walkers' were a single model of droid, The Essential Guide to Droids ("B'omarr Brain Walker") states that 'the brain walkers do not follow a single overriding design pattern'.
