Problems solved by technology

[0002] Aiming at the fatigue of teachers who stand on the podium for a long time in class, it will reduce the efficiency of class. Some courses need to draw pictures on the blackboard constantly, which often results in a lot of class time wasted on drawing pictures. During the process of drawing pictures, the dust generated by chalk will be sucked into the teacher’s mouth. Cause respiratory diseases, so there is an urgent need for a machine that can help teachers draw pictures and write, and can make teachers sit down
