A method for providing host instructions to a control module of a modular assembly system is provided. A graphical programming environment including sets of first and second graphical representations is presented to a user. Each first graphical representation corresponds to a statement block comprising a parameter. Each second graphical representation corresponds to one of assembly modules associated with a property. A user is facilitated to select at least one of the first graphical representations and provide values to the parameter of each selected first graphical representation. The user is facilitated to provide values to the property of one or more of the second graphical representations. Based on at least the selected first and second graphical representations and the provided values thereof, a set of host instructions are generated. The set of host instructions are transmitted to the control module for controlling operation of the assembly modules.

A toy comprising a frame and an inverting toy. In some embodiments, the inverting toy includes an invertible shell having a first surface and a second surface, the invertible shell configured to protrude outward in a first direction with respect to the frame until a depressing force on the first surface or the second surface in a second direction causes the shell to invert and protrude in the second direction with respect to the frame, wherein the first direction and the second direction are substantially opposite, an edge member formed at an edge of the invertible shell and configured to secure the invertible shell to the frame, and a pulling member formed on and protruding outward from the first surface of the invertible shell.

An assembly unit includes side plate having first coupling member on first side, second coupling member on second side, and third coupling member on each of third and fourth sides, top plate including fourth coupling member and top stud, and bottom plate including fifth coupling member and bottom stud. The first coupling member is engaged with the second coupling member of neighboring side plate. The fourth coupling member is engaged with the third coupling member. The fifth coupling member is engaged with the third coupling member. The first coupling member includes protrusion. The second coupling member includes groove. The protrusion is fitted into the groove of the neighboring side plate. The third coupling member includes thread. Each of the fourth and fifth coupling members includes thread. The fourth and fifth coupling members are engaged with the third coupling member in a screwed manner using the threads.

A wearable toy system comprising a wearable component, a toy housing and at least one replaceable toy; wherein the wearable component comprises at least one fastening member for securing the wearable component to a part of a user's body; wherein the toy housing comprises a toy-receiving base and a cover, the toy-receiving base being adapted to receive at least a base member of the replaceable toy, the toy-receiving base and the cover together defining a void for accommodating at least a part of the replaceable toy when the base member is received by the toy-receiving base and when the cover is in a closed state; wherein the toy housing defines at least one opening when the cover is in the closed state, the opening allowing one or more parts of the replaceable toy to extend out of the toy housing.

A toy construction set comprising a number of toy building blocks with one or more coupling knobs and coupling sockets adapted for releasable frictional engagement with the couplings knobs on another building block in the toy construction set, and wherein the toy construction set further comprises a building element comprising a bistable band, and where the band has a first stable shape where it is curved about a first curvature axis extending parallel with the longitudinal direction of the band and at a distance from a first side of the band, and a second stable shape where it is curved about a second curvature axis extending substantially perpendicular with the first curvature axis, and where the bistable band on the first side of the bistable band comprises multiple coupling knobs arranged in a uniform, preferably square pattern, and where each coupling knob is adapted for frictional engagement with a coupling socket of another building block in the toy construction set.

A multi-function modular robot apparatus provides a wide range of entertainment and functional use options that may be tailored by a user to the specific entertainment and functional purposes so desired. The specific entertainment and functional purposes of the multi-function modular robot apparatus are obtained through inclusion of multiple stackable modules. The interlocking mechanical and electric communications connections for each stackable module act as a power and electronic communication pass through to allow for each module to be arranged in any order and in any combination while still maintaining power and function.
