The independent variable was the surface. The dependent variable was the speed. The controlled variables were the robot and the code or program. An independent is something that is changed in an experiment. A dependent variable is what changes depending on the independent variable which in this case is the floor surface. The controlled variables are the factors that stay the same.
Independent variable = carpet, tile, blacktop
Dependent = Speed
Controlled variable = robot and program
