Stem relates to doing robotics. Math relates to robotics because making the robot go so many inches, yards, feet or wheel rotations is math. Calculating the robot to go a foot and a half has to be calculated to wheel rotations. Engineering is the building of the robots making it have the right things just to make it do what it does. Technology is the class we are doing it in. Technology is using the computer to program the robot and to download it onto the robot. Science, if this robot was actually doing work in the fields its science making the robot do that. If there was a robot on mars exploring and analyzing data that is science. That is how Science, Technology, Engineering and Math relate to robotics.
