I had been working with Poya and Hayato for these couple months before the tech fair. During these months we have built a robot which could solve a rubik's cube in under 3 minutes. From scrambled up to solved in less than 3 minutes.

My partner, Poya was presenting it while I was away for the ski trip, he had turned it into a shooter which was based off a motor rotating and pushing a stick at force to shoot plastic balls. He appeared to have designed a score board to shoot into and accumulate points. Below is a picture of the shooter
