In Iron Man, Tony Stark’s small workshop robot is named Dum-E.
Dum-E is a simple industrial-style robotic arm used in Stark’s laboratory. It helps handle equipment, retrieve objects, and assist with the construction and testing of Iron Man technology. The robot is especially recognizable for its clumsy movements and for carrying a fire extinguisher during laboratory accidents.
Tony also has a second workshop robot named U. The two machines are often confused because they appear together and perform similar tasks, but Dum-E is the robot most frequently identified by name in the film’s workshop scenes.
Dum-E is not JARVIS, the artificial intelligence that manages Stark’s mansion and systems. JARVIS is software, whereas Dum-E is a physical utility machine operating beside Tony’s workbench.
