time machine (doraemon)
Depiction of a time machine from Doraemon. Or more specifically the one used by Doraemon himself. They appeared as a flat, flying carpet-esque device with a console at the front and a lamp at the right side. Though other models of the time machine were also appeared within the series.
While under time travel, the machine will enter a "time tunnel" with similar traffic and policing as the actual road and then create a portal at the entrance/exit point.
