How to build a simple robotic arm from Lego Mindstorms NXT?

Today, I will tell you how I built my robotic arm from Lego Mindstorms NXT. In fact, I wanted to build a robotic tripod for my camera. I found out, that it's more difficult then it looks.

After some experimenting I build this simple robotic arm. I you want to build it too, you need: - Lego Mindstorms NXT kit - a computer - time...? There are only two rules you have to follow while building ANY robot: 1. Rule: KISS (Keep it simple, stupid!); 2.

Rule: "The triple-F" rule a.k.a. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
