301-MAX
this was the model number of Kalibac Industries' Nightlight security droid. A small, spherical droid equipped with a combat-enhanced repulsorlift generator, the 301-MAX was designed to patrol a specific area and seek out intruders or breaches of security. A number of sensor packages were added to the system, and a ionization buffer helped protect the 301-MAX from any ion blasters. This ionization buffer was a major breakthrough for droid manufacturers, since it helped eliminate the need for additional plating.
