Darren built this robotic arm for a high school project. it can be controlled either via Bluetooth using a smartphone or via IR using a TV remote control.
So how did the idea of a robotic arm come to me? Well, the first thing I remember is our chemistry teacher (!) coming to me yelling that she has a project for me. It was for science Olympiad, however, apparently it was different from all the others, “something related to electronics” (that’s what she said!) and since I had a bit of a reputation in the school for my skills with robots, she thought I would be the right person to ask from!
And well, what could I say to the teacher? I accepted, and she put me in the team. Next thing I remember is my dad yelling at me for the $200 I spent for the equipment I needed, and next… well, the robot was built!
