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 & Bakrepeating blaster cannon. The droid also featured a TranLang I communications module and a vocabulator, though it was only able to speak droid languages.
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". 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.
One of the modified B'omarr version, seemingly without a brain, was present on Jib Kopatha's home, Void Station, in 0 ABY.
It is revealed in the non-canon story Tag & Bink Are Dead that Tag Greenly and Bink Otauna are the two stormtroopers who mention the BT-16 in the conversation posted above. However, as the story itself is non-canon, so is this information.
