This robot arm has a story behind it!

I decided to build this robot to fancy the girl I'm crushing on in the university.

So I rememberd that there is a problem while we present a presentation on front of the class, that we always need a friend to switch the slides for the presenter. I designed this bot to click next button on the keyboard to switch me the slides! watch it while it works here: https://youtu.be/l1ofJZVoFAU

Luckely she was amazed but I never saw her again :'( but it still a cool project to share with you guys :)

I used arduino mega and Bluetooth shield that helps me to control it wirelessly. and positioned it in front of the next button on the keyboard, so when it lays down it presses the button perfectly.

Using 3 servos to control the bot:

x2 MG995 servos x1 Micro servo I only controlled one servo on this project as I only need to lay down for the keyboard. Other servos can be used in any other mission if needed.
