Abstract

This invention relates to an intelligent mathematic instrument. It includes an axis portion, a rotatable rod portion, an outer diameter adjusting bar, a central processing portion, and a power supply. The rotatable rod portion is pivoted on the axis portion and can rotate around. The outer diameter adjusting bar is disposed on and movable along the rotatable rod portion. A drawing tool can be mounted on the outer diameter adjusting bar. The central processing portion is able to control the rotatable rod portion and the outer diameter adjusting bar so as to draw a predetermined line, curve, etc. So, this invention can automatically draw many kinds of lines or curves. In addition, it is easy to use.
