Scenario

First we had the initial idea for the project, making several sketches on paper, physical prototypes and elaborating on the project with the entire team guesses until we have a final model of scenario that would be perfect for the gameplay and trying to get a good user experience for control of robot .
To implement the idea, use cardboard boxes for the installation of roads, white ribbons in order to delimit the runway and build some obstacles that determines the difficulty of the game. The closer the end of the scenario, the harder it is the obstacle.

Programming

The player, in case the robot will track the user, is controlled from a device that has the Android OS installed, along with the NXT Remote Control application found for download on Android Market for free.
Already the autonomous robot, or the opponent of the player, is controlled by programming based on an ultrasonic sensor that when viewing the player coming close to him, it triggers a sequence of commands that makes walking around the scene, there is a dispute with the User to reach the other point of the scenario, or the finish line.
