Work Robot
From Wikitroid, the Metroid wiki
[edit] Description
A stubby little robot in the Space Pirate Mothership and in the Wrecked Ship. They fire small round shots in Super Metroid, while Zero Mission's are unarmed but are annoying when Samus has to go through one to escape. Both forms are immune to damage, but missiles can cause them to waddle quickly, getting them out of Samus's way. They also appear in the Metroid E-manga.
