We used an Oddwerx Robot (www.oddwerx.com), to complete the task of playing Tic-Tac-Toe as a virtual avatar. You play the game through a website which talks to the MyRobots.com cloud, and then the Oddwerx robot also talks to the cloud and finds out what the latest move was made, and places physical blocks on a physical game board. This is our video submission to the Hackathon. We had 48 hours to implement this game. We started on Friday night, and were done on Sunday afternoon. The only thing we had was a plan, and ended with a working game at the end, after some late nights, and lots of hard work.
We have launched a Kickstarter to make Oddwerx robots into a reailty. Sign up and get your robot! http://www.kickstarter.com/projects/ologic/oddwerx-autonomous-smartphone-robots
