Small light is a lamp similar to a flashlight that will shrink objects and people to minuscule sizes. Its opposite is the big light (ビッグライト?), which enlarges objects and people. Another tool that is used in a similar capacity is the Gulliver Tunnel, which causes a person to grow or shrink depending on which entrance he takes; however, its ratio of shrinking and enlarging is fixed. Unlike the Gulliver Tunnel, however, the effect of the Small light is not permanent and will wear off after a period of time has passed (seen in the series to be anywhere from a few hours in the comics to a few days in the movie Doraemon: Nobita’s Little Star Wars)
One of Doraemon’s most commonly used gadgets is the dokodemo door, a door which allows travel to anywhere by simply going through the door. In an early story, the door is able to travel to the end of the universe, but in later chapters, the door is said to only be able to travel a maximum distance of 100,000 light years and cannot access other dimensions. Another limitation of the door is that it can only safely connect two known locations in its mapping computer, which also has a limited range of information based on Time as shown in the movie “Nobita’s Dinosaur.”
One of the main modes of transportation for the various characters is the take-copter, which combines the words taketombo (bamboo dragonfly, the Japanese name for the bamboo-copter), and part of the word herikoput which means helicopter. The take-copter was also called the heri-tombo in early stories. The device is a propeller attached to a tiny suction cup which can be attached to enable flight. Ever since the first few Doraemon stories, the take-copter is seen attached to the head instead of the waist, similar to a propeller beanie, due to a mishap with Nobita’s shorts. The take-copter has also been attached to objects to enable its flight. One of its disadvantage is its short battery life. Have a build in batteries, speed 80km/hour of 8 hours continous operation possible, if fly slower the battery will last longer. Have some sort of anty-grafity mechanism to blog earth’s gravity. How to use: Just imagine the direction and speed and your thought will transmitted to the mechine. it can move / fly freely. In the first appearence it was called “Dragonfly Helicopter” but after that it was called Take Copter.
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, and a clock with five hands overhanging the 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. The time machine can create an exit in a specific place spatially as well as temporally. An alternative to the time machine is the time belt, which does not change the wearer’s location relative to Earth. The presence of this machine is not known by Nobita’s mother.
This time mechine is invented in 2008. How to use: select the button to chioose the destination time, then check the sensor and start the mechine. The lever in the left is for speed control. This mechine also have the voice recognition, just say the destination and the mechine will start. In the Long Story ” Nobita and the Robot Kingdom” Doraemon make a modification to the navigation mechine so it can also move in time and space (super space).
Size of the time mechine: length: 2.2m, height: 1.28m, width: 1.6m, weight: 538kg.
The mechine need soem time to start.
Dorami also have the similar time mechine: Space Time Tulip.
Fourth-dimensional pocket / 4D PocketThe inside of this pocket connects to the fourth dimension and acts like a wormhole. It is usually shown attached to Doraemon’s abdomen. Doraemon has a spare pocket which connects to the same location. Nobita has used the spare pocket on ocasion, often for mischievous purposes but sometimes for helpful purposes (for example, he used it to save Doraemon on the movie Nobita and Tin-Plate Labyrinth).
