Technical support droid

The technical support droid, or tech-support droid, was a droid model utilized by the Republic Navy during the Clone Wars to service hyperdrive docking rings.

Details
Tech-support droids were small units engineered to operate in zero gravity. Operating in orbit, the droids monitored the docking procedures of Jedi starfighters like the Eta-2 Actis-class interceptor with Syliure-45 hyperdrive modules. They also ensured the starfighter was properly secured to the ring before departure. The droids were fitted with yellow lights that turned green when the transport ring was correctly oriented, allowing the pilot to depart.

History
When Jedi Master Obi-Wan Kenobi departed Coruscant for Utapau towards the end of the war, two tech-support droids helped orient his transport ring for his hyperspace journey.
