The workbee, also known as a cargo management unit or extricator, was a small utility spacecraft utilized by the Federation from the late 23rd and 24th centuries. It was an apparent successor to the worker bee from the 2250s.
As the workbee was primarily a maintenance craft, it could be equipped with a variety of tools, including a set of dual remote manipulator arms called the Grabber Sled. The workbee could also serve as a tug for cargo modules with the Cargo-Train Attachment. (citation needed • edit)

Following the design's first appearance in The Motion Picture, the moniker "Work Bee" was adopted by many publications, official and unofficial, including the reference work Star Trek: The Motion Picture Blueprints, co-created by Andrew Probert and David A. Kimble. The name itself would not be "canonized" until the name appeared on a display graphic appearing in the Star Trek: Prodigy episode "Starstruck", previously Star Trek: Discovery had otherwise adopted the similarly named "worker bee" nomenclature for similar craft.
According to the Star Trek: The Next Generation episode "Coming of Age" this vehicle was identified in an okudagram as a "cargo management unit", and in dialogue (while referencing the okudagram) as an "extricator".
The workbee was designed by Probert for Star Trek: The Motion Picture. He later remarked, "The work bee turned out just fine."  The studio model of the workbee was filmed in the summer of 1978, on one of Douglas Trumbull's stages at Future General Corporation. (The Making of Star Trek: The Motion Picture, p. 206)
Despite being proud of the workbee's design, Probert also felt that, in The Motion Picture, not enough articulation was shown in the craft. For instance, he believed that "it would have been fun" to see the workbees enter a garage area that was included in the film's drydock. "There were supposed to have been numerous Bees, doing whatever tasks with their manipulator arms, or towing things, or whatever, and they didn't show enough of that," Probert commented. "And [...] I would have liked to have seen them drifting, or moving, or gliding/crabbing sideways through space, or rotating. They do have one that kind of rolls... but there should have been a lot more of that."  An unused design for the Enterprise cargo/shuttlebay showed several docking ports where workbees could attach to the ship, which were described in Mr. Scott's Guide to the Enterprise.

The workbee was additionally seen in footage recycled in Star Trek II: The Wrath of Khan and during the Enterprise-B launch in Star Trek Generations. The craft was physically brought to the 24th century when it was included in a montage of different scenes during the main titles of Star Trek: Deep Space Nine, beginning with that series' fourth season. These scenes were also used for external shots of the station in various episodes. A computer-generated model was also created, and seen at Utopia Planitia during the flashbacks to the USS Voyager's launch during "Relativity".
Probert designed a follow-up craft to the workbee, dubbed the Sphinx Workpod, during the first season of Star Trek: The Next Generation. Although it was never built as a miniature or explicitly seen, it may have been included in the matte painting of Starbase 74 in "11001001". The new workpod was also featured in the Star Trek: The Next Generation Technical Manual and Star Trek: Starship Creator.
In Star Trek: The Experience's Borg Invasion 4D exhibit, Sphinx Workpods can clearly be seen repairing Copernicus Station after its brief encounter with a Borg cube. It remains the most visible and intricate use of this design.
