Workbee

A Work Bee is a type of small utility craft which is used throughout the Federation. The name is derived from the work bee's small size and distinctive yellow color.

The Work Bee's had entered service by the 2270s and many were assigned to the Starfleet shipyards orbiting Earth, including the San Francisco Fleet Yards. 

By the 24th century, Work Bee's were also assigned to Federation starships as part of their complement of auxiliary vessels. In 2372, Captain Jean-Luc Picard ordered command-level lock-outs to be installed on the Work Bee's and other auxiliaries assigned to the USS Enterprise (NCC-1701-E).
