Abstract: A construction kit comprises a plurality of building modules, wherein at least one of the building modules is functional and adapted to perform a specific behavior. In some embodiments, each of the building modules includes at least one connection face adapted to pass either data or power from a first face of a first building module to a first face of a second building module. In certain other embodiments, each connection face of the building modules is electrically connected with each of the other faces. The kit includes at least one connector adapted to couple the at least one functional module to at least one other module while providing up to three degrees of freedom between the functional module and the at least one other module.
