meArm User Interface: (3) Testing the Crane Game

Testing the crane game.  For our specific function/task, we wanted our robot to replicate the movements of an arcade crane/claw game.  If you watch the video, you can check out some of our crane game shenanigans; we weren't ever actually able to grab the candy off my hand, but hey, these crane games are supposed to be difficult!  It adds to its charm.

Above is what our code looks like every time the "Pickup" function of the crane game is run.  It functions as a series of five steps: (1) the opening of the claw, (2) the lowering of the claw, (3) the closing of the claw, (4) the raising of the claw, hopefully with item in tow, and (5) returning the claw to its starting position.  Getting the code to run smoothly was tricky at first, but the code we wound up with seems to work quite well.

The next blog post will demonstrate the cleaned-up UI, with not only just the crane mode but the completed free mode as well.  After that, we're ready to take on the ROBOlympics with our MeArm and custom UI!
