Abstract: An assembly block with a servomotor includes: a block main body having at least one connector including a protrusion or a recessed portion; a servomotor; and a rotation shaft which is configured to be rotationally driven by the servomotor. The assembly block with the servomotor is connectable to a basic block by fitting the at least one connector of the block main body to one or more connectors of the basic block. The assembly block with the servomotor includes a rotary block which is defined as a polyhedron, has, on a surface thereof, at least one connector including a recessed portion or a protrusion, and is fixed to one end of the rotation shaft such that the rotary block can rotate. An assembly block kit includes the assembly block with the servomotor, and basic blocks connectable to the assembly block.

Abstract: An assembly block with a servomotor enabling assembly of various works without requiring special parts used for a drive shaft only includes: a block main body having connection means including a protrusion or a recessed portion; a servomotor; and a rotation shaft rotationally driven by the servomotor. The assembly block with the servomotor is connectable to a basic block by fitting the connection means of the assembly block to connection means of the basic block. The assembly block with the servomotor includes a rotary block which is formed of a polyhedron, has, on a surface thereof, connection means including a recessed portion or a protrusion, and is fixed to one end of the rotation shaft and rotates. An assembly block kit includes the assembly block with the servomotor, and basic blocks connectable to the assembly block.

Abstract: To provide a block having a simple shape by itself with which various three-dimensional structures can be obtained by devising connection states, the invention is directed to a regular hexahedral block connectable with at least another block by fitting a protrusion provided on a surface of one of the blocks into a recessed portion provided in a surface of the other block, in which one protrusion having a square cross-sectional shape is formed at the center in one quarter section of a surface of the regular hexahedron, and in which a recessed portion into which the protrusion is fittable is formed at the center in each of two to four quarter sections of any other three surfaces of the regular hexahedron.
