Qbot control using iPod's sensors and gesture recognition

This video shows a Qbot mobile robot (based on iRobot's Create platform) being commanded by an iPod Touch held in a user's hand. As the hand is tilted forward and tuned to the right, the iPod's accelerometer data is used to command the Qbot to move forward and turn to the right, respectively. Alternative iPod interfaces allow the Qbot to be commanded to a specified position on the grid.
