Re: Robot bumpers

Often times, when people discuss the 'weight bonus' that comes with using bumpers, what they're talking about is the benefit that an additional 15 lbs. has when calculating the force of friction between the playing field and your robot's traction surfaces.

Force of friction is calculated as some coefficient of friction (mu) times a normal force. In this case, that normal force is the weight of the robot, so a higher weight provides for a higher force of friction.

More friction makes it more difficult for others to push your robot when it's standing still. The added weight doesn't allow for any benefit to mechanism design or robot function, however.
