A toy construction system comprising toy construction elements comprising coupling members (20) for detachably interconnecting the toy construction elements to create spatial structures (40), the toy construction system comprises at least a first type of toy construction elements (10), the first type of toy construction elements can be coupled to each other, wherein that the first type of toy construction elements is configured to be detected by a touch screen (60), and when toy construction elements are coupled to each other so as to form a spatial structure, the toy construction elements of the first type define a touch point pattern recognizable by the touch screen.

Implementations described and claimed herein provide systems and methods for delivering a customizable feedback stimulus. In one implementation, a custom feedback device comprises a shell housing having a first shell and a second shell. The shell housing opening extends between an outer surface of the first shell and an outer surface of the second shell. A plurality of protrusions extends between the first shell and the second shell, and at least one receiving area is defined by the plurality of protrusions between the first shell and the second shell. The receiving area is adapted to house a customized portion.

A structure comprising two shell parts connected to each other with at least one snap connection, the two shell parts comprising, on the inner side, mutually complementary male and female snap means configured to form a snap connection, and complementarily configured abutment faces that abut on each other when the male and female snap means are interconnected. The male and female snap means comprise an external spiral-shaped protrusion configured on the male snap means, and a complementarily configured, internal, spiral-shaped protrusion configured on the female snap means configured to engage. The structure comprises rotation-preventive means configured such that the two shell parts are unable to rotate relative to each other when the male and female snap means are interconnected to form at least one snap connection.

Circuit blocks are provided. A circuit block may include a substrate and at least one electrical component mounted on the substrate. The circuit block may also include a non-conductive frame coupled to the substrate, and at least one post coupled to the substrate and extending from the substrate and through at least a portion of the frame in a first direction substantially perpendicular to the major surface of the substrate. Moreover, the circuit block may include a contact coupled to a second, opposite surface of the substrate and including a corner section projecting outwardly from the frame and extending in at least two directions substantially perpendicular to a longitudinal axis of the at least one post. The block may also include at least one magnet positioned proximate the flexible corner section of the contact and configured to magnetically attract at least one other circuit block.

A set of interlocking blocks consists a plurality of first blocks and a plurality of second blocks capable of forming kinematic interlock. Each of the first blocks and second blocks comprise at least one male joint and female joint for mating with its counterpart. The motion of the first blocks and second blocks are constrained by joints. Subsequent first blocks and/or second blocks reinforce and immobilize prior first blocks and/or second blocks. Assembly of an interlock structure consisting the set of interlocking blocks may be performed via translation motions.

A modular wing, adapted to be used on a flying device such as a toy airplane, drone, or other small fixed wing flying device, or form a part of a wind turbine or any other apparatus that requires a wing or blade, that is compatible with all block-based toy systems such as LEGO, DECOOL or KAZI. The modular wing is comprised of a series of modular aerodynamic surfaces that may be suitable for manufacture by a low-cost method such as molding or additive manufacturing such as 3D printing, typically but not necessarily from plastic, to form wing sub elements which, when assembled together, form a wing or blade such as an airplane wing or turbine blade. The modular wing may comprise cambered or symmetric wing shapes. The modular wing may be used in a static display model fully flying aerodynamic aircraft, sailing hydrodynamic boat, or aerodynamic functioning turbine.

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.

A toy building brick system includes a brick having an upper wall and an outer wall that is attached to and extends downwardly from the upper wall. The outer wall has a bottom edge that is a free edge. The outer wall bounds a receiving space configured to releasably engage a male connector such that the outer wall and the receiving space defines a female connector. The outer wall has a first notch and a second notch therein each extending upwardly from the free edge and to the upper wall. The first and second notches form grips to facilitate removal of the brick from a male connector.

A toy building brick system includes a brick which has an outer surface including a plurality of outer walls. A male peg is attached to one of the outer walls. The male peg is configured to engage a female connector and includes a post having a terminal end. The terminal end has an outer peripheral edge. The outer peripheral edge has a notch positioned therein. The notch faces an adjacent edge of the outer wall attached to the male peg to prevent adjacent male pegs of adjacent bricks from abutting in such a manner that the male pegs bias the adjacent bricks apart from each other.

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.
