A mobile, spherical robot includes a spheroid shell, an internal assembly secured to the shell, and a head disposed atop the shell. The internal assembly is disposed within the shell for propelling the mobile robot. The internal assembly includes a base, a flywheel assembly rotatably secured to the base, a drive assembly rotatably secured to the spheroid shell and configured to propel the mobile robot by rotating the spheroid shell about the base a pivoting arm pivotably secured to the base, and the pivoting arm. The head is secured to the magnetized end of the pivoting arm through the spheroid shell. The head is configured to move relative to the spheroid shell and relative to the base by the pivoting of the pivoting arm.

A toy vehicle launcher comprising a housing defining multiple inlets and an outlet. The housing further defines a cavity in which a resilient rotating member is located. The resilient member is positioned to engage an upper surface of a toy vehicle passing through the housing. A crank arm is coupled to the housing and movable by a user to rotate the resilient rotating member to propel the toy vehicle.

The present invention provides a self-righting model vehicle.

A hand-held gyroscope toy or gyroscopic muscle conditioning device with an outer shell containing a drive assembly with a spring-loaded drive button at one end that charges and discharges the gearing inside to provide an accelerated rate of rotation to a flywheel inside the outer shell. The resulting high-speed rotation causes a gyro effect that can be employed as either a fidget-type toy or a resistance device for fine motor or muscle development.

A process for self-righting an inverted remote controlled model vehicle is provided. The process includes the method of determining a current pitch angle and a current angular rocking rate of the model vehicle and accelerating or decelerating a mass on the model vehicle based on the current pitch angle and the current angular rocking rate of the model vehicle to create a rocking motion by the model vehicle. In addition, the method also includes terminating the self-righting process when the model vehicle is upright. In which, the model vehicle body contacts the ground and provides a fulcrum for the rocking motion by the model vehicle.

Provided herein are devices for propelling string through the air. The device includes two wheels, a motor, a head, a handle, a detachable cover, and at least one UV light source. At least one of the two wheels can be operable to be driven by the motor. The two wheels can be rotatably mounted to the head and form a gap operable to receive a portion of the looped string. The device can further include one or more heat sinks coupled to the at least one UV light source and/or motor.
