Like others of its class, this roughly humanoid-appearing medical droid has surgical manipulation appendages, a medical diagnostic computer and a treatment analysis computer. For detailed patient status information, 2-1B relies on medical instrumentation or useful analysis droids like the FX-7.
The most useful characteristic of the 2-1B droids is the ease with which owners can update their programming and appendages. In addition to that, 2-1B droids can easily become experts in medical fields such as neurosurgery, podiatry, paediatrics, cybernetic limb replacement and alien biology. This makes the 2-1B a very sought after droid in markets across the Galaxy.
