Gyroscopic precession is the resultant action of a spinning object when a force is applied to this object. This action occurs approximately 90° in the direction of rotation from the point where the force is applied. Gravity pulls it down and angular velocity Torque lifts it up, keeping it afloat while spinning. We design and build a prototype "VEX IQ BeyBlade" using VEX IQ 60T,12T,Linear gears: transferring up to 3000 RPM to the spinning Top

Gyroscopic precession is the resultant action or deflection of a spinning object when a force is applied to this object. This action occurs approximately 90° in the direction of rotation from the point where the force is applied. In nature this act is evident when leaves falls from tree. When spinning, the leaf takes more time to hit ground, like resisting the gravity. This is the force that acts opposite to spinning Top that keeps it afloat while spinning. But there must be some minimum speed requirement. The formula for calculating minimum revs per sec, required to keep top spinning is "square root of ratio g/a" , where "g" is gravity and "a" is radius of spinning top. We made a VEX IQ BeyBlade using linear gear and circular gears to het 1:25 gear ratio. We can get up to 3000 RPM on the spinning top, keeping it spinning and floated.
