Tetrahedron Machines 3D Tetrahedron

Printer-friendly page

The Tetrahedron Machine is the simplest Platonic solid brought to life as a dynamic mechanism. This polyhedral sculpture has four corners, four sides, and six edges made of air cylinders connected by flexible joints. Under air pressure the cylinders extend and contract, changing the shape and volume of the robot in interesting ways. Three Tetrahedron Machines have been built so far, conceived as interactive art under human or computer control.
