Fig. 2: Representation and Elements of a metatruss Design.

a A 1D integer array serving as the design representation. This array encompasses C-network indices, contraction levels, and on/off control signals. b In a quadruped robot example, each beam designated a unique C-network index indicated by color. c Preset contraction ratios r derived from the product of contraction level and a fixed increment, Δ = 0.12. d Task-specific sequences of on/off control signals assigned for actions like walking and turning.
