Methods and apparatuses are disclosed that rotate a first member about a first point relative to a chassis, wherein the first member is rotatably coupled to a second member at a second point. A second member is counter-rotated at a ratio of the rotational speed of the first member wherein the second member is rotatably coupled to the third member at a third point. The third point is translated in response to the counter-rotating second member in oscillatory motion along a path. The third member is pivoted at a third point and fluid is moved in response to the motion of the third member. A force is applied to the chassis due to the interaction of the third member and the fluid.

What is claimed is: 1. A method comprising: rotating a first member about a first point, wherein the first member is rotatably coupled to a second member at a second point; counter-rotating the second member at a rotational speed that is related to the rotating wherein the second member is rotatably coupled to a third member at a third point; translating the third point in oscillatory motion along a path wherein the translating is responsive to the counter-rotating; and pivoting the third member at a fourth point. 2. The method of claim 1, wherein the rotational speed of the second member is twice the rotational speed of the first member. 3. The method of claim 1, further comprising: moving the third member through a fluid wherein a force is imparted to the third member. 4. The method of claim 3, wherein the fluid is air. 5. The method of claim 3, wherein the fluid is water. 6. The method of claim 1, further comprising: changing a stroke path angle of the third member while the third point is being translated in oscillatory motion. 7. The method of claim 1, further comprising: varying a pitch angle of the third member during the counter-rotating. 8. The method of claim 7, further comprising: moving the third member through a fluid wherein a force is imparted to the third member. 9. The method of claim 8, wherein the fluid is air. 10. The method of claim 9, wherein the fluid is water. 11. The method of claim 7, wherein the varying provides a pitch angle that is constant. 12.
