Yosarius

The Yosarius was a First Federation ship commanded by Gobot. It saved the SS Clydesdale from an Orion Raider then Gobot insisted that they remove Dr. Janet Corbair as Empress of the planet Dirt, which was under First Federation protection. Mike Harper was able to get Corbair back onto the Clydesdale, and Gobot allowed them to leave in peace. ("Reign of the Clydesdale" [TOS])
