                        Analyzing Your Walker

                        This model is made so that it can perform the correct walking
                        motions on only one motor. An essential part of this walking
                        mechanism is the opposite-pointing cams. What if the cams were
                        not pointing in opposite directions? How would the walker walk if
                        the cams were pointing in the same direction? Or in perpendicular
                        directions? You can test these motions with the hand crank at the
                        back of the model or by running the motor.
