A three-dimensional (3D) self-reconfigurable system made of identical units is proposed. Each unit has six arms on the surface of its base cube which can connect to neighboring units mechanically. By the connection, a cubic-lattice structure is formed. A unit can carry its neighborunit from one node of the lattice to another by rotating its arm by 90°. Repeating this movement, the structure can reconfigure itself to realize various 3D structures. The general process of reconfiguration was proposed for this system. A prototype system including six units was madeand basic motions of self- reconfiguration were verified.
