The present invention provides a spinning toy comprising novel structure and design. The spinning toy includes a main body provided with blades, each of which can be provided with weight modules. The weight modules are provided with counter-weight members, of which the positions are adjustable. A bearing having an upper finger cover and a bottom finger cover is mounted in the center of the main body. By pinching the two finger covers via fingers, a user can hold the toy and suspend the main body between the fingers, and then slightly flicks the blades with the other hand to enable the blades to spin; and when the positions of the counter-weight members of the weight modules are adjusted, as the gravity center is no longer evenly distributed, the user can make the blades spin for a long time by swinging the toy in a proper rhythm. This structure not only allows the spinning toy to spin for a long time, but also renders it possible for the user to adjust the spinning speed by swinging the toy in a proper rhythm.

A combination finger ring, movable spinning object and a hard candy fixed in position by an exterior post. The finger ring may include a novelty ring housing. The exterior post extends from the finger ring and supports the movable spinning object at the exterior post between the affixed hard candy and the finger ring. The exterior post may include an axle portion supporting the movable spinning object. The movable spinning object may include a circular rotary object propelled into motion by the flick of a finger or by blowing on the movable spinning object which is freely movable and spins relative to the finger ring. The movable spinning object may include a round disk, the surface of which may include a printed design, label or sticker with colors or patterns on the round disk. A rainbow swirl image or the like may be generated while spinning the disk for further amusement.

A method and apparatus for charging a battery with a finger actuated low mass spinner electromagnetically converts the mechanical spinning energy to the desired battery charging voltage. The charger may be a self-contained portable battery charger unit for use with any of multiple devices containing respective batteries, or it may be a permanent part of such a device. The spinner may be a modified fidget spinner to which a shaft or axle is fixedly attached to rotate about that axis with the spinner and has one or more permanent magnets secured for rotation therewith. Alternatively the spinner may be more like the fidget spinner, without an axle rotating therewith, and having magnets on its rotating arms. In either case, the magnetic fields of the rotating magnets induce voltage in one or more induction coils to generate a battery charging voltage.

A fidget tool phone case having a case body, a spinner assembly comprising a spinner housing, a spinner base, a bearing, a spinner arm, and a spinner hub, a click wheel assembly comprising a wheel housing, a wheel housing cover, a plurality of springs, and a plurality of wheels, a slider assembly comprises a slider housing, a slider housing cover, and a slider, and a button assembly comprising a plurality of button housings, a button housing cover, a plurality of button bases, and a plurality of buttons. The spinner arm spins freely relative the case body. The plurality of wheels rotates with resistance from the plurality of springs. The slider moves along a channel aperture of the slider housing. The plurality of buttons is depressible through the plurality of button housings. The fidget tool phone case thus provides a plurality of engagement options for a user.

A handheld spinner includes a housing, a holder, a ball bearing, and a stationery item. The stationery item is disposed on the housing and includes a pencil, a pen, a marker, a highlighter, a crayon, a brush, a stylus, a stamper, an eraser, and/or chalk. The ball bearing is disposed in the holder and the holder is disposed in the housing. In one embodiment, the handheld spinner includes a cap disposed on the holder and the ball bearing. In one embodiment, the handheld spinner includes a holder, a ball bearing, and a stationery item. In one embodiment, the stationery item is a plurality of stationery items spaced apart by discrete angles. A user rotates the handheld spinner about the rotational axis of the ball bearing, which spins the stationery item or items. The handheld spinner is useful as a fidget toy and houses multiple stationery items on a single device.

A robot is provided. When a value obtained by excluding a gravitational component from an acceleration detected by an acceleration sensor is continuously less than a reference value for a certain time, a travelling state of the robot is determined as frictional surface travelling. A control circuit calculates an attitude angle of the robot from an angular velocity in a pitch direction, which is detected by an angular velocity sensor. When the calculated attitude angle is a lower limit angle or more for a determination time, the control circuit sets the attitude angle at the end of the determination time as an attitude control angle. When the travelling state of the robot is determined as the frictional surface travelling, the control circuit moves a counterweight frontward by a movement amount corresponding to the attitude control angle.
