Well, the story of Doraemon is really extensive. Doraemon was sent back in time by Nobita's great - grandson because Nobita was having such a hard time in his present life. Doraemon uses his various gadgets like the 'Anywhere Door' which can take you to any place you want instantly, and the 'Memory Bread' that helps Nobita study (although with some comical side effects). It's a story full of friendship, adventure, and lessons about growing up as we follow Nobita's experiences with Doraemon by his side.
Briefly, Doraemon is sent to Nobita from the 22nd century. He has a pocket full of gadgets. They deal with Nobita's school and life problems and have fun adventures.
