Abstract: The present disclosure discloses a measuring and drawing device. The measuring and drawing device comprises a supporting frame, a rotation driving portion, a reciprocation driving portion, a drawing member, a distance measuring sensor, an angle sensor, and a control module. A first motor is configured to drive the rotating arm to rotate relative to the supporting frame, and a second motor is configured to drive the drawing member to reciprocate along the rotating arm to enable the drawing member to move in two dimensions. The distance between the first motor and the drawing member is measured through the distance measuring sensor to achieve measuring of a length of a line segment, and the rotating angle of the rotating arm relative to the first motor is measured through the angle sensor to achieve measuring of the rotating angle.
