One of the main modes of transportation for the various characters is the take-copter, which combines the words taketombo, and part of the word herikoput which means helicopter.

Time Machine

The entrance to Doraemon's time machine is in Nobita's desk drawer. The time machine looks like a simple platform with a control console. Doraemon is often seen piloting the time machine. Dorami has her own time machine shaped like a tulip, suggesting a variety of models available in the future.
