If I were to list some of the most dangerous habits observed in the way programmers work, I would definitely put making assumptions on this list. Let me explain. Recently, I have been debugging this one unit test that was showing signs of being a false positive. Turns out I was right about that and the reason was really simple – someone made an assumption that turned out to be false. Let’s face it – we have all been there at least once in our career (even once sounds too good to be true 🙂 ). We assumed that certain situation, outcome or combination of several factors is simply not going to occur only to receive a bug report confirming that this assumption was wrong. This often unconscious practice is really common and causes trouble all over the world.
Now, that the arm is assembled it is time to take it to the next level. It is time to unleash the beast and gain full control of the whole robot arm. By the end of this post you should have an idea of how to program this robot arm to do what you want it to do. To see how I got here please visit my previous article describing the assembly process – Build your own robot arm – assembly.
