In Saturday of this week in Isai ambalam school, students are doing different tasks. One group of students was building EV3MEG robot using Build a Robot documentation of MINDSTROMS EV3. The day before (Friday) students had partially completed the Robot structure. Remaining structure of Robot is finished on Saturday and they played with a Robot manual by controlling motors on EV3 brick. Students felt it is annoying and they want It to do task automatically by programming. But there is problem in a laptop which was used to program it. Then they found out LEGO MINDSTROMS commander mobile app with help of volunteer in their school. Using the mobile app (which had GUI mode) they created GUI command for controlling motors and they connected their Robot with mobile app using Bluetooth and presenting their Robot to all students and teachers in school.
