Doraemon: Explanations for sleeping habits and gadget usage

Explanations have been provided regarding the lifestyle and behavioral constraints of the character Doraemon from the popular series.

Doraemon sleeps in a built-in wardrobe in Nobita's room rather than a proper bedroom. This is attributed to his feline-like instincts, as cats often prefer small, dark spaces. Additionally, the limited space in Nobita's home and Doraemon's significant weight of 129.3 kg make sharing a bed impractical.

Regarding the use of futuristic gadgets for financial gain, Doraemon is prohibited from using his tools to make money. Using time travel to manipulate events, such as buying winning lottery tickets, is considered a violation of future laws. Such actions are monitored by the Time Police to prevent the disruption of social order and historical progression.
