Abstract: A movable robotic module including a framework defining a set of vertex elements, a set of edge elements, or a set of face elements, with the framework substantially shaped to permit face centered cubic packing. Each module includes a pivot mechanism on its framework to permit rotation of the framework with respect to other movable robotic modules. A power unit supplies operational power to each module, the power being used for rotation of the module, sensor and/or a control unit connected to the pivot mechanism and/or the power unit to control rotation of the framework.
