When the robot has retrieved the object, he or she goes to the end of the line and becomes mission control. The person at the head of the line now becomes a new robot. Repeat until all objects have been retrieved. When the game is over, return to the classroom and discuss what happened. Discuss what things worked for communicating effectively and efficiently with your robot.
E-mail a direction for someone in the other class to follow.
After they have followed your direction, they will send e-mail back to you, letting you know that they have completed the task. Keep track of how long it takes to communicate this way.
