A radio-controlled model vehicle is provided including a model vehicle chassis, a vertically mounted motor, and a rear axle, configured to pivot in a vertical direction relative to the model vehicle chassis via one or more rear axle linkages. The rear axle also includes a vertical rear axle differential. The model vehicle further includes a gear reduction transmission including a spur gear comprising spur gear teeth offset from a spur gear center portion, and a pinion gear engaged with the spur gear teeth. In addition, the model vehicle includes a vertical, extendable driveshaft that has one end attached to the spur gear center portion and another end attached to the rear axle differential. Wherein the driveshaft extends through the spur gear and the motor powers propulsion wheels coupled to the rear axle via the gear reduction transmission, driveshaft and rear axle differential.

A rotating joint assembly such as an interface device in a master device or remote manipulator for a puppeteering device or other mechanical system operating in response to operator input and requiring more than 360 degrees of rotation. The rotating joint assembly includes a hard stop assembly that limits the rotation of its rotating component(s) to a predefined maximum amount of rotation such as to less than two full revolutions, e.g., some rotation amount between 360 and 720 degrees. The hard stop assembly includes a Geneva drive body or driven wheel with a hard stop body rigidly coupled with the Geneva drive body to rotate it between a disengaged position (during the first revolution) and one of two engaged positions by rotation of an inner ring (at some point during the second revolution in either direction).

An animatronic doll having a motor, a head frame pivotally mounted to a neck carrier, a bevel gear and a pinion gear connected to a head shaft, a first gear, and a second gear. The pinion gear is engaged with a rack of the head frame. The first gear is configured to be driven by the bevel gear and is rotatable between a first position, a second position, and a third position. The first gear does not drive the second gear when the first gear is rotated between the first position and the second position. The first gear drives the second gear when the first gear is rotated between the second position and the third position. Rotation of the head shaft rotates the pinion gear and pivots the head frame. Rotation of the second gear may rotate arms of the doll. The arms may include friction clutches.

A gear mechanism having a shuttle gear adjacent both an auxiliary gear and an action gear and a cam plate, having a shuttle lock adjacent the shuttle gear and including a cam follower riding back and forth along a first cam pathway with an action element in mechanical communication with the action gear. A motor operates the shuttle gear with rotation of the motor in a first direction rotating the shuttle gear into engagement with the auxiliary gear, activating the shuttle lock to maintain the engagement throughout a predetermined rotational range of the cam plate and rotating the cam plate back and forth driving controlled back and forth movement of the auxiliary elements, with rotation of the motor in a second direction rotating the cam plate beyond the predetermined range releasing the shuttle lock.

A turntable toy includes a housing and several turntables, a toggle assembly, a transmission assembly and an elastic member. The housing is provided with an accommodating chamber, an opening, and a sliding chute. Some of the turntables are accommodated in the accommodating chamber. An accommodating space is further provided in the housing. The toggle assembly is located in the accommodating space. The toggle assembly is rotatably connected to the housing and is rotated between an initial position and an end position. A driving end of the toggle assembly is at least partially threaded out of the sliding chute. The transmission assembly is located in the accommodating space and corresponds to the opening. The elastic member is connected to the housing and the toggle assembly. The elastic member enables the toggle assembly to have a motion tendency to move from the end position to the initial position.
