Zeno Droid Technologies (ZDT) is a small start-up droid company based in Nar Shaddaa. While ZDT has not been a huge player in the droid manufacturing industry, they still make a few products that appeal to those who know droids. ZDT is known for their droids ease of modification and repair, which makes them desirable for tinkerers.
Based off Ferroprol Corporation’s EK4 Stevedore droid, the ZDT-555 is a 5th degree droid built for its raw power and its ability to operate in hazardous environments where the vacuum of space, the heat or the extreme cold is dangerous to sentient workers. The "Barrel" got its name due to its barrel-chested frame, often compared to the stature of large primates due to its short legs, long arms and barrel-shaped torso. Due to its ruggedness, the ZDT-555 "Barrel" Labor Droid is often seen refitted and used in droid gladiatorial matches.
Whereas the ZDT-510 is sold mostly for domestic and indoor type settings, the ZDT-555 is used as a droid workhorse for many factories and manufacturers who crave power and reliability.
