‘Smart rolling-ruler’ it is a portable size but it can draw a limitless line as the flexible display of the ruler rotates 360 degrees and moves forwards like the caterpillar tracks.
The display shows the changing gradations and measurements to measure them clearly.
The smart device rolling-ruler is marked in various units as well as the basic unit of cm, and has the automatic transformation function.
The measurements are marked in the display automatically at the time of measuring the length.
Because the ‘smart rolling-ruler’ has a wide range of functions such as a unit conversion, a calculator, and a memo as well as a ruler, it plays the role of a smart educational device.

Problem 1
It is inconvenient to carry a 30cm ruler, and it is difficult to measure a larger size than 15cm or to draw with a portable 15cm ruler. If a line is drawn with the 15cm ruler while in motion, it is slanted or it is difficult to draw.
Problem2
We use different size of rulers, calculators, and pens in various situations such as drafting, drawing, designing, making a blueprint, or calculating figures in math.
