Models for some smart toys and extensions

Abstract

Toys based on a Top (which is a simple gyroscope) reveals some interesting property of a gyroscope to be able to dynamically keep the direction of its spinning axis in space and also, to dynamically stand up on its end. Some smart toys had extended these properties. As example: (1) in Pumped Top, by compensating electrically the losses of its energy and then, allowing the Top to stand up the time that is pumping. (2) in Power Ball, where well synchronized mechanical external torques allows the Top to increase its spin speed and then, to display much stronger external torques. (3) in Levitron, where a special Top equipped with a permanent magnet can fly even in steady state. Analyzing these Tops lead to the fact that a gyroscope, when external torques are applied, develop a lifting force. This lifting force correspond to the reunion of the gyroscopic torque pulses during a precession period that try to restore the initial angles in space of its spinning axe. Some interesting extensions lead to a gravitational aerial, gravitational-electromagnetic resonator and to a gravitational motor. More, some (maybe naive) models for atomic particles and inertia are also presented. All these may leads to an other approach of the associated wave and inertia. © 2013 Springer Science+Business Media.
