“C Language” Programming Education from Intelligent Robotics Education System

RES-485 Robotics Education System

“C Language”Myths:◦C Language is difficult.

Typically, C training education includes difficult or unusable contents. Also it uses grimmer-centered way of thinking Ex. file input/output function and file struct

◦C Language is not interesting. Induce making a C programming rely on standard input/output

function from beginning to end All it shows is all numbers or characters on computer screens are

boring.

However, C Language is:◦An essential yet fun requirement for IT students.

C Language Programming

Students are more motivated from excitement. To do this:◦Something appealing to their eyes◦ Including Movement, and◦Sound

The best toolare“Robots”

C Programming Learning

Outline of Education Kit◦ Robotics is one of the best educational materials to show and

demonstrate creativity to students.◦ This Creative Robot Kit is designed to give a creative engineering

education as well as programming education for utilizing robots.◦ Fully variable assembly accessories and motors are provided to a make

variable and applicable robot◦ Variable creative modules (different types of sensor, actuator, and

communication module) are included to control robot◦ Provides environment for C Language development and Visual

Programming Language development tool◦ Provides a powerful 3D robot simulation environments◦ Learning the variable configuration designs and self movement control of

robot including robot motion recognition and self detection are possible.

#include<stdio.h>

void robot_go(){

Motor(1, 602); /* Right Leg */ delay(200); Motor(2,602); Motor(3,602); delay(200); Motor(1,512);

Motor(0, 422); /* Right Leg */ delay(200); Motor(2,422); Motor(3,422); delay(200); Motor(0,512);}

void robot_stop(){
