Provided is a wheel-shaped self-assembly connection member including a wheel of a circular shape, and having an internal space that is partitioned into a plurality of fan-like shapes; a protruding circular connector of a cylindrical shape protruding from a center axis of the wheel in a direction to perform as a driving axis, the cylindrical shape having a female void performing as a connector; and circular connectors located in the fan-like shapes in directions of north, south, east, and west in the wheel, each of the circular connectors having a center void performing as a connector.

In one example, we describe a method and system for structural basic units and their connectivity devices, apparatuses, or systems. These can be used for games for kids or for instructional purposes for math and chemistry or physics modeling. In another application, it can be used for the real-life situations, e.g., to build strong usable structures for storage, housing, and bridges, using the fundamental bricks and modules or connectors shown here, e.g., in a large size or scale. In another application, we can put glue or cement or concrete or mortar or construction material or other adhesive, as solid or liquid or tape or fluid, between the bricks or fundamental units or pieces or joints, for better adhesion. Other variations, systems, and features are also discussed here.

Provided is an assembly toy including an internal cylindrical body, an external cylindrical body surrounding the internal cylindrical body and having a spiral recess in an internal side surface thereof, and an insertion member inserted to a void in the internal cylindrical body to be engaged with and coupled to the internal cylindrical body. When the insertion member is rotated, the internal cylindrical body moves along the spiral recess in the internal side surface of the external cylindrical body.

Provided is a toy block. The toy block includes a first rotator formed on a body, a second rotator on an outer portion of the first rotator, and a gear portion switching a rotation movement of the first rotator to a rotating movement in an opposite direction to transfer the rotating movement to the second rotator.

A toy figurine mount assembly includes a mounting block having a top side, a bottom side and a perimeter surface. The top side is planar and the bottom side comprises a female interconnection member to releasably and frictionally engage a male interconnection member from a building block system. A coupler releasably engages a foot of a toy figurine. The coupler is attached to the top side of the mounting block.

A framing system for a construction set comprising a number of interchangeable elements which can be arranged to construct a variety of three-dimensional structures, as well as individual, stand-alone floors, which in turn are adapted to be stacked on one another. In some embodiments, the system comprises at least one central unit, a plurality of outer mid-columns, at least one tie beam corner unit, and/or at least one curved beam unit which cooperate to form a variety of stand-alone floors. The system comprises additional components which increase the stability of the construction set, including but not limited to internal corner brackets, cross pins, cross studs, square panels, and rectangular panels.

The present disclosure relates to an IoT-based modular robotics system where a function button for changing from a program mode to an automatic mode is installed in a master block, enabling instant execution of the automatic mode in the master block.

An active lattice capable of self-transforming responsive to a stimulus, such as heat or moisture, includes a plurality of links interconnected to each other at a plurality of nodes. At least a subset of links includes at least two materials that have different coefficients of expansion in response to an external stimulus. The two materials can be arranged in an alternating, periodic or aperiodic pattern. Embodiments can be used in apparel and sportswear, manufacturing, aviation and automotive applications, and furniture and interior products.

In a first aspect, a construction toy element is provided and includes a body and a first circumferential row of arms extending from the body. The body has an axis, and has a first axial end and a second axial end. A first circumferential row of arms extends from the body. Each arm includes a root end and a free end, and has a first connecting member thereon that is configured for connecting the construction toy element to another construction toy element. The root end projects from the body in a direction that is angled towards one of the first and second axial ends relative to a normal direction to a surface of the body.

The present disclosure provides a modeling apparatus having a plurality of modeling devices, each having a generally tetrahedron shape having four faces with an interface element attached to each face. Each interface element cane b removably and rotatably coupled to an interface element of an adjacent modeling device. A combination of modeling devices are selectively couplable to form a variety of structures such as molecular, architectural, artistic, dynamic, and/or any other suitable model. The interface elements can include magnets with distinct or identical polarities, and with selective strengths to emulate the target structure or assembly attributes. They can also be iron or a neutral material such as aluminum. The vertices of the modeling apparatus include a curvilinear boundary tracing a spherical periphery of a sphere having a radius extending from a center point of the tetrahedral shape to a midpoint of an edge thereof.
