We have used for loop used which is a repitition tool, since there for the arm 2 or link 2 creates different angle for the same angle of link 1, without using for loop, the prohram will be lengthy and difficult to interpret.

PS: I was travelling for the past week, so couldn\'t submit the project on time and also I don\'t know how to attach the animation video file. I\'ve atatched the screen shot from the anime file. I kindly request you to provide me with the week 3 and week 4 of the matlab videos.
