A simple tetrahedron prototype was constructed to analyse the corner joints and surface angles. Through the analysis, extendable support (legs), which will be replaced with actuator motors in a 1:1 scale, were adopted to automate the structure. The extension capability allowed the model to contract and expand and subsequently, the order of the extension action of each individual leg allowed the model to automate and ‘walk’. The same system was adopted for the octahedron prototype.
