AccuTronics made a notable entry into the fifth-degree labor droid market with their B1 worker droid. While the CLL-8 binary load lifters were commonly employed in freight operations due to their substantial size, the B-1 worker droid served as a smaller counterpart to these massive machines.
Its programming was similar to its larger brethren, which equated to a simplistic, literal mindset which was nonetheless appropriate to the drudgery of heavy manual labor, which required little more than great strength. B1's would take orders from anyone. Its cargo claws were designed with suction pads for added grip, and its reverse articulated legs were aided by a third retracting leg which was used for added stability during lifting of bulky loads.
During the period just prior to the Clone Wars, AccuTronics fielded a nuna-ball team composed of B1s. This team was defeated by a Serv-O-Droid team featuring RIC-series droids, which were quicker and more agile than the strong but lumbering cargo droids.
These droids were used at Radell Mining Corporation headquarters. The heavily armed Imperial defense droid used on-board the original Death Star was of a similar design.
The cost is listed as 9,800 credits (new) and 6,400 credits (used) in The Rebel Alliance Sourcebook, Second Edition and Platt's Smugglers Guide, but the Arms & Equipment Guide states a price of 800 credits.
