 artificial intelligence. It deals with design, construction and programming of the robots. Here we at Elpro International School emphasize on robotics for primary as well as secondary level where students work in team and learn the cooperative skills in making their projects. Students learn to work in team and it's really nice to see them working in groups and it enhances their cooperative skills. It is so interesting to see students getting excited to see their models work. The line for our program it basically just follows the line. We have used our color sensor in which it is a mode which is RLi which is a reflected light. Basically when the color sensor gives out a red light and then that light is reflected back to the sensor which figures out how dark or light it is and according to that it gives the color a certain value which is then used to perform some certain tasks. What we have done is that we've taken the average of both of the colors. One is the color of the table which we took as brown and the other of the tape which is blue and we calculated both of their averages and then we took that as a base value. So we're telling the robot that if it's below that bar value then you have to move in certain direction and if it's above then you have to move in the opposite direction and according to that it follows the line. Pyrograph, a drawing robot. Wispy, a pyrograph is a geometric drawing toy that produces mathematical roulette curves of a variety. A robotic pyrograph makes these curves. We constructed an EV3 model which helps us in fetching a object so in this case we have built a small object in which the EV3 model goes up to a particular distance along with the touch sensor it brings the object back and releases it. It works like bomb, release and press. So what happens is the touch sensor presses and releases the object.
