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.
