Of course we expected complications. We also expected unexpected complications, but somehow they still caught us by surprise. Our most recent of these particularly difficult problems is the arm.

I can safely say that we are thrilled to have an arm on our robot. I can also safely say that the arm we have is far from what we were shooting for (no pun intended). Our current model works more as a navigation and terrain tool than it does a catapult. We were aiming for the high goal, (pun intended) but our high speed motor can’t even come close to producing enough torque.

Because of the awkward timing and shortage of parts, we attacked this problem indirectly. We kept the motor, but added some medical tubing. This is sort of like a giant hollow rubber band. You’ve probably seen this on heavy duty slingshots. Now our robot even further resembled a catapult. Our motor still didn’t have enough tourque to make the shot. Not only that, but it couldn’t even pull back the arm against the tubing. To make this work, we tried several different positions, but to no avail.

Mr. Anderson then crafted a custom gear for us. Honestly, it was sub-optimal, no offense. On the bright side, it could now make the shot with ease. The last remaining flaw was the medical tubing. Our robot couldn’t pull back the arm, even with our special gear! We had to have the robot done by the next night. Had we forseen this problem, we could’ve been shooting goals a full day earlier!


We tabled the problem, and satisfied ourselves with obliterating defenses and shooting low goals.
