DOT-7

DOT-7s were a type of worker robot in operation in the 2250s through the 2280s aboard Federation starships like the USS Enterprise. They were distinguished by a vaguely humanoid silhouette with a head and robotic manipulator arms, and, though they lacked legs, they possessed four maneuvering thrusters on their backs.

DOT-7s were stationed in engineering aboard the Enterprise. Capable of anti-grav flight, the DOT-7s maneuvered between engineering levels performing tasks such as welding. (ST: "Ask Not")

During the Battle near Xahea, several DOT-7s were deployed after an undetonated torpedo fired by a Section 31 ship became lodged in the Enterprise's forward section. (DIS: "Such Sweet Sorrow, Part 2")

Dot, a DOT-7 in 2267

By 2267, DOT-7s still operated aboard Constitution-class ships, distinguished by red markings and antler-like extensions on their heads. During this time a DOT-7, identified as Dot, had an extended interaction with a mycelial tardigrade, identified as Ephraim, that lasted from the 2260s to 2285. (ST: "Ephraim and Dot")

In 3189, after receiving damage from the Battle near Xahea in 2258 and then crashing on The Colony, the USS Discovery was repaired by DOT-7s and worker bees. (DIS: "People of Earth")

Later that year, working alongside the more advanced DOT-23s, DOT-7s participated in the retrofitting of the USS Discovery. (DIS: "Scavengers")

DOT-7s were also used in the mirror universe, such as on the ISS Discovery in 2255. (DIS: "Terra Firma, Part 1").

Background information

An experimental repair robot

There is precedent for repair robots in the Fifteenth UK Story Arc, published in 1970. The experimental machines, on loan from a research depot on Venus, worked on the Enterprise in a story set between 2267 and 2269. Although more humanoid than DOT-7s, they possessed similar manipulator "hands".
