Lego Walker using Lawsin Linkage

Image
The Lawsin Linkage:  Lawsin Linkage Simulation The Lawsin Linkage , sometimes called the Bowtie Truss,  is a double cantilever truss system with connecting elements (links) forming triangular frames. The structure, which forms like a bow-tie or a double inverted king posts, was developed by Joey Lawsin in 1988 to simulate the walking cadence of  his biotronics animals. The linkage was designed to meet the following criteria: 1. It must carry out a walking cadence fluidly like an actual living animal's gait. 2. It can conquer any type of terrain obstacles from carpet floors to seabeds. 3. It can move in different directions with various range of actuated motion or R.O.A.M. 4. Its structure elements must be guided by natural mathematics, eg. geometry. 5. It can be integrated with the arduino platform for virtual consciousness programming. The linkage is consisted of two equilateral triangles that are connected in a common pivot axis known a pin joint. T...
