Abstract: A system includes multiple assembly modules and one or more connectors. Each assembly module includes at least one connection interface, and each connector includes two open ends adapted to fitting into the connection interfaces of the two assembly modules, respectively. Each connector is configured to mechanically and electrically connect two of the assembly modules via the respective connection interfaces of the two assembly modules. The assembly modules include at least a control module having a communication unit and a processor. The communication unit is configured to obtain a set of host instructions from one or more hosts. The processor is configured to generate a set of operation instructions for each assembly module based on at least the set of host instructions.

Abstract: The toy vehicle is characterized in that a rear excavator is fastened to the toy vehicle, that a seat boom is rotatably arranged on a receiving block which is fastened to the toy vehicle, that a support leg is mounted on the receiving block and is pivotable between a raised position and a lowered position in which the support leg rests on the ground, and that the receiving block has mounted thereon a securing hook means which in a first position locks the support leg in the raised position and, at the same time, locks the seat boom in a predetermined angular position and which in a second position secures the support leg in the lowered position and, moreover, releases the seat boom for rotation. The toy vehicle can also be operated by small children and meets high safety standards.

Abstract: A mechanical arm generally intended for use as a toy or game element comprises a base rotatably supporting a turret. A first link connected to the turret by a shoulder joint, a second link connected to the first link by an elbow joint, and an end effector connected to the distal end of the second link. A first lever with a handgrip drives the first link, a second lever with a handgrip drives the second link using a drive cable and pulleys mounted in the interior of the first link. The end effector is controlled by a lever attached near the second handgrip. A control cable is threaded through the hollow interior of the mechanical arm to operate the end effector.

Abstract: An assemblage of robotic modules includes a plurality of robotic modules, with each robotic module having memory capability, an actuator, a joint position sensor, and communication means. The assemblage of robotic modules also includes a distributed control unit, which is defined at least in part by a plurality of individual central processing units, with each robotic joint module having at least one central processing unit.

Abstract: A rope drum gear for a child's toy, for example a toy crane, is constructed such that a child can operate an elevating mechanism and a grab spade by way of ropes via the drum gear. A crank handle for actuating the mechanisms is connected to a split rotating drum by way of crank case wheel. The hub of the crank case is constructed as a sun wheel of a planetary wheel gear, which planetary wheel gear is in turn connected with a first half of the split rope drum. The first half of the split rope drum is connected via a rope to the grab spade operating mechanism. The first half of the drum when rotated engages the second hair by way of a clutch mechanism, the second half of the drum connected by a rope to the elevating mechanism of the crane. In this way, a child can reproduce the operation of a full-scale crane in a manner easy to operate and understand for the child.

Abstract: A combined snow shoveling device and cart for removing snow from surfaces in one mode of operation and for hauling debris in another mode of operation includes a scoop arranged with a reinforced front edge for scooping snow or other material from a surface and temporarily holding the collected material, a support frame arranged with a handle portion and four wheels which are designed for movement across a surface. A first linkage member is attached to the scoop and to the support frame such that as the support frame is pushed across the surface by means of the four wheels resulting in movement of the scoop across that surface. A second linkage member is attached to the first linkage member and to the scoop and is arranged in order to change the orientation of the scoop such that any collected debris or snow can be elevated and moved to a remote site and then the orientation changed again into a dumping mode so as to empty the scoop of any collected material.

Abstract: A toy mechanical digger includes a base frame member, a longitudinally-extending base beam pivotally mounted on the base frame for manually-actuated, 360.degree. slewing action relative to the base frame, a seal longitudinally slidably mounted with respect to the base beam; a primary boom having a pivoted end, and intermediate end, and a remote end, the pivoted end being pivotally mounted to the forward end of the base beam, such that the remote end can be raised and lowered, the intermediate end pivotally mounted to the forward end of the seat such that forward and rearward longitudinal sliding movement of the seat is linked to the lowering and raising movements, respectively, of the primary boom; a secondary boom having a pivoted end and a remote end, the pivoted end mounted on the remote end of the primary boom for pivotal movement relative thereto.

Abstract: A dumping mechanism for a dumping toy truck with a rear deck is disclosed, which is provided with a covering element for preventing invasion of dust and gravel through a large hole for a lifting rod, as well as a buffering pad for a bearing shaft for the rear deck and a flexible buffer at the lower end of the lifting rod for absorbing any sudden shock or loading applied by an infant.

Abstract: A toy having a pivotable component in the form of a construction wheel loader having a shovel, the toy including a manually actuable handle cocking a spring coupled to a slidable member having a rack portion for operating the shovel. Movement of the slidable member during cocking of the handle simultaneously moves a coupler connected to a piston slidable axially within a stationary closed ended cylinder. The piston has a minute aperture in the face thereof with a larger aperture in the skirt thereof with the apertures being on opposite sides of the piston seal. A locking lever coacts with the coupler for retaining the parts in the powered position against the force of the spring. Manual release of the locking lever permits the spring to urge against the slidable member with the two apertures in the piston providing speed regulation during movement of the piston into the cylinder for moving the slidable member gradually.

Abstract: A toy shovel is provided. The shovel comprises a seat, a first arm pivotally mounted on the seat and extending forwardly therefrom, a second substantially vertical arm pivotally mounted at its upper end on the first arm, a shovel mounted for pivotal movement on the lower end of the second arm, a first handle pivotally mounted on the seat and secured to the first arm for controlling the depth of the cut made by the shovel, a second handle pivotally mounted on the seat, and linkages interconnecting the second handle and the shovel for controlling the pivotal movement of the shovel.
