R1-Series Astromech Droid

The R1 was launched immediately after the P2 was pulled from the market. Following the P2 lawsuit, Industrial Automation's funds were low, so IA used leftover hull casings from their Mark II Reactor Drone series to encase the R1 astromech droid instead of developing and producing a new shell for it.
  Although (much like the P2) the R1 generally filled the roles of technician and repair droid, they had one great improvement over their predecessors. While a P2 unit could only remember the direct hyperspace route between two systems, the R1 could be given a new set of coordinates and calculate the course itself. Although this detail seemed trifling at first, it quickly became important when one was trying to find a database containing droid-ready data on a less frequently used hyperspace route. It might take several hours to find information on a route from Naboo to Kiffex so that a P2 could make the trip, but a R1 would only need around twenty standard minutes to calculate the path. This was largely due to the Intellex III computer that served as the droid's CPU.
  The R1 was still very large for an astromech, standing two meters tall and nearly twice as broad as later IA astro droids. In order to fit the R1 into the Mark II reactor drone's shell, the R1 was given a single leg with tracks on the bottom to allow movement instead on the three legged format of the P2. This treaded unipod was prone to failure, stranding the droid in one spot.
 R1-Series astromech droids can be played as droid heroes.
