Tensegrity, tensional integrity or floating compression is a structural principle based on the use of isolated components in compression inside a net of continuous tension, in such a way that the compressed members (usually bars or struts) do not touch each other and the prestressed tensioned members (usually cables or tendons) delineate the system spatially.
Tensegrity structures absorb energy and with wheels on it, could act as an excellent chassis, being rigid when it needs to be and plastic when huge loads are placed on it.
