The wings only help because the robot was designed poorly. When the robot moves without wings the body of the robot jumps up and down and it rotates along a vertical axis, and that makes it hard for the robot to move. The wings stabilize the motion of the body and presses it towards the ground, and that allows the robot to move faster.

Therefore this experiment does not prove a lot. The team is asking the right question, but they did not come up with a denifite answer.
