As the shuttles move back and forth, each along its channel, all points on the rod move in elliptical paths. The motion of the rod is termed elliptical motion. The semi-axes a and b of the ellipses have lengths equal to the distances from the point on the rod to each of the two pivots.
the foot has to touch the ground for at least half of the cycle for a two/four leg mechanism [1] or respectively, a third of the cycle for a three/six leg mechanism; minimized moving mass; vertical center of mass always inside the base of support [1] the speed of each leg or group of legs should be separately controllable for steering [6]
Side view of the LH-10 Ellipse exhibited at the 2008 Farnborough Air Show. The LH-10 Ellipse is a low-wing, tandem two-seat light kit aircraft, powered by a 100 hp Rotax petrol engine in a pusher-propeller configuration. Its low weight and unusual configuration is designed to deliver a very high cruising speed with exceptional fuel economy. [2]
Theo Jansen's linkage. When the blue line at the right end of the picture is driven in a clockwise rotary motion, the leg (blue triangle at the bottom) executes a walking motion.

The FM H-10-44 was a switcher locomotive produced by Fairbanks-Morse from August, 1944–March, 1950. The units featured a 1,000-horsepower (750 kW), six-cylinder opposed piston prime mover , and were configured in a B-B wheel arrangement mounted atop a pair of two-axle AAR Type A trucks , with all axles powered.
Various forms of actuation and force transmission can be achieved through these inspired designs, including rotation, lifting, and even damping effects. [8] The passive nature of the hydraulic and elastic extensor mechanisms employed have found use in orthotics projects aimed at assisting joints weakened by age or disease.
