The class will be divided evenly into relay teams and each team will stand in a straight line. There should be ample distance between teams. Each team should have the same objects and the objects should have similar placement across the teams. The first person in line is the robot. The last person in line is mission control.
All teams begin at the same time.
Mission control needs to decide what commands need to be given to the robot, one command at a time, in order to have the object retrieved. The robot performs the command and tells the person behind him or her that he or she has done so. That person informs the person behind him or her, and so on, until the message reaches mission control. Mission control sends another command in the same manner. When the robot has retrieved the object, he or she goes to the end of the line and becomes mission control.
