Gripper for a robotic arm.

The motivating factor for the construction of this robotic arm originally came from a tour of the Volvo factory in Göteborg, Sweden. It was during this factory tour that I first saw the massive robotic arms used to pick up car parts and weld them on to the car body. With sparks flying, these were some of the most impressive robots I had ever seen, and if you ever have a chance, take the tour!

Fast forward one month, and I was the proud owner of my first robotic arm kit, a Lynxmotion AL-5D, with the heavy-duty wrist rotate mechanism. Oh boy did I have big plans for this arm! Having some previous experience with Arduino boards, I immediately connected an Arduino Uno to the SSC-32 servo controller that came with the arm. With a little bit of web searching, I was able to find instructions and sample code which had me sending basic commands to each servo. It took another couple of weeks, but I had finally gotten the arm to move the way I wanted. Continue Reading
