A system and method is provided for a toy race track. Preferred embodiments of the present invention operate in conjunction with a vehicle affixed to a track, wherein the track is supported in relation to at least one fixed surface via a plurality of support structures. In one embodiment, the track comprises a plurality of flexible sections, allowing a user to construct a track resembling a rollercoaster, having steep curves, upside-down portions, etc. In one embodiment, the vehicle includes a plurality rollers that can be used to both affix the vehicle to the track and propel the vehicle along the track. By affixing the vehicle to the track, the vehicle is prevented from leaving the track during extreme situations (e.g., steep curves, upside-down portions, etc.).

The invention relates to the utilization of magnetism in the roll stabilization and suspension of a radio-controlled car. In small radio-controlled vehicles, in particular, it is difficult to implement the conventional mechanical roll stabilization and a well-functioning suspension due to the small size, the accuracy required, dirt, and the loads exerted on the structures. In the structure according to the invention, the roll stabilization and suspension are implemented by means of magnetism, according to FIG. 2. The magnets at the ends of supporting arms (6) attract each other, implementing the roll stabilization. Magnets (3) are installed under the supporting arm magnets, repelling them and providing suspension.

An activity box includes two pairs of wheels having blind holes, two axles having two ends releasably insertable into the blind holes, and a box defining a space having a defined volume sufficiently large to fit the axles. The wheels include a first magnetically attractable component. The axles include a second magnetically attractable component secured at each end of each axle. The axles have a length spanning a width of the box, which has two pairs of through holes on two opposing sides to accommodate the axles, such that the axles are threaded through the through holes. The two pairs of wheels are rotatably attached to the box by magnetically coupling the first magnetically attractable component to the second magnetically attractable component, such that the activity box is configured to be used as a cart that can be rolled over a surface.

Robotic systems according to the invention include a frame or body with two or more wheels rotatably mounted on the frame or body and a motor for independently driving each wheel. A system controller generates a signal for actuating each motor based on information provided by one or more sensors in communication with the system controller for generating feedback signals for providing reactive actuation of the motors for generating one or more functions selected from the group consisting of forward motion, backward motion, climbing, and balancing. A power source is included for providing power to operate the drive motors, system controller and the one or more sensors.

Disclosed in embodiments of the present application is a toy car, including: a chassis, where the chassis includes a first end portion, a middle body portion and a second end portion which are arranged in a first direction; two first wheels arranged at the first end portion and spaced apart in a second direction; two second wheels arranged at the second end portion and spaced apart in the second direction; and a first driving member and a second driving member which are both mounted at the middle body portion, where the second driving member and the first driving member are arranged in the first direction and/or the second direction, and the second driving member is configured to drive the two first wheels to turn. By means of the toy car provided in the embodiments of the present application, the situation that the mass and size of the first end portion are far greater than the mass and size of the second end portion can be reduced, thereby reducing the rollover probability of the toy car during traveling. In addition, the structure of the present application has the characteristic of high adaptability, and can be adapted to various low-height sports car simulation models with space limitations, thereby increasing the degree of simulation of the toy car, and improving the playability of the toy car.

A propulsion system for an aerial vehicle or toy aerial vehicle includes a bladeless fan drive and a peripheral ground-engagement part. The bladeless fan drive operates in a plane (x′-y′) and is configured for producing thrust. The peripheral ground-engagement part comprises a hubless wheel and a rotatable tire component. The bladeless fan drive is secured within the hubless wheel by two pivot points on opposing sides of the bladeless fan drive, such that the plane of the bladeless fan drive is pivotable about a pivot axis (x′) spanning between the two pivot points, the pivot axis (x′) being orthogonal to a hubless wheel axis (z) of the peripheral ground-engagement part.

A clearance compensation device for a model car includes: a guide part which is provided on the bottom surface of the model car and has a guide rail formed along the vertical direction; a clearance compensation part which is provided to the guide part, has a bottom surface that is in contact with the upper surface of a panel having a runway formed therein, ascends and descends along the guide rail in response to the shape of the upper surface of the panel when the model car travels, and is configured to compensate for a clearance between the bottom surface of the model car and the upper surface of the panel; and a magnetic body which is provided to the clearance compensation part and provided at the lower side of the panel with the panel therebetween to be coupled with the lead member movable in the horizontal direction.

A body mounting assembly, model vehicle, and method for engaging a model vehicle body to a model vehicle chassis are provided. The body mounting assembly includes a latch assembly. The latch assembly further includes a latch member with a latch engagement surface. The body mounting assembly also includes a retainer assembly. The retainer assembly further includes a retainer engagement surface. The latch assembly is releasably engaged to the retainer assembly when the latch engagement surface and the retainer engagement surface are interlock together. The latch engagement surface and the retainer engagement surface comprise negative engagement angles. A body mount able to be coupled to a model vehicle body includes one of the latch assembly or the retainer assembly and a chassis mount able to be coupled to the model vehicle chassis includes the other corresponding retainer assembly or the latch assembly corresponding to the body mount.

A model vehicle with body mount components are provided. A tongue member attached to a model vehicle body with a first and second tongue member is configured to engage a first securing member attached to a model vehicle chassis. A top surface of the second tongue member draws the model vehicle body towards the model vehicle chassis when the second tongue member engages the first securing member. A lever member with a lever handle, jaw clamp, and a lever pivot is configured to pivot between an engage and an unengaged position. The jaw clamp engages with a second securing member in the engaged position. The lever member further contains a retaining mechanism that is configured to rotate between a retained and unretained position. The retaining mechanism inhibits the lever handle from moving from the engaged to the unengaged position when the retaining mechanism is in the retained position.

In one aspect, there is provided a toy vehicle that includes a vehicle body, at least one motor and a plurality of wheels. The at least one motor is mounted to the vehicle body, and is sized to have a selected amount of torque. The plurality of wheels includes at least one driven wheel which includes at least one flip-over wheel which has an axis closer to one end of the vehicle than the other end. In an upright orientation the vehicle body extends above the plurality of wheels. The toy vehicle has a centre of gravity that is positioned, such that, application of torque from the at least one motor causes the vehicle body to drive rotation of the vehicle body about the axis of rotation from an inverted orientation over to the upright orientation.
