연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

The rotating toy of claim 1, wherein the hub includes an upper portion above the plurality of counter rotating blades and above the main rotor such that the toy includes a center of gravity above a bottom portion of the outer ring. 3. The rotating toy of claim 2, wherein the center of gravity is positioned above the bottom portion of the outer ring at a distance that is between about ⅓ to 쩍 a diameter defined by the main motor. 4. The rotating toy of claim 2 further comprising a dome positioned on an upper portion of the hub. 5. The rotating toy of claim 1, wherein the motor mechanism rotates a drive shaft connected to the main rotor. 6. The rotating toy of claim 1, wherein the main rotor has a diameter less than an internal diameter defined by the outer ring. 7. The rotating toy of claim 1 further comprising a wireless controller that controls a rotational speed of the main rotor. 8. The rotating toy of claim 1, wherein said end of each blade, of the plurality of blades, includes a first portion connected to said outer ring and includes a second portion positioned about a circumference defined by an internal diameter of said outer ring. 9. A rotating toy comprising: a hub; a plurality of counter rotating lifting blades extending outwardly from the hub, each counter rotating lifting blade, of said plurality of counter rotating lifting blades, includes an end connected to an outer ring; a main rotor positioned below the hub for generating a major portion of the lift therethrough such that the toy is able to fly; and a center of gravity positioned above a bottom portion defined by the outer ring along a central axis defined by the hub. 10. The toy of claim 9, wherein the main rotor includes a diameter less than an internal diameter defined by the outer ring. 11. The toy of claim 9 further comprising a motor mechanism for driving the main rotor, and an internal space defined by the hub for housing at least a portion of the motor mechanism. 12. The toy of claim 9, wherein the bottom portion of the outer ring is below the lower portion of the hub. 13. The toy of claim 12, wherein each blade of the plurality of counter rotating lifting blades, has a downwardly and an outwardly slope from said hub to said outer ring. 14. The toy of claim 9 further comprising a control mechanism for controlling the rotational speed of said main rotor. 15. The toy of claim 14, wherein said control mechanism is controlled through a wireless controller. 16. The toy of claim 15, wherein said wireless controller is an infrared wireless controller. 17. A rotating toy in combination with a remote controller comprising: the rotating toy including a hub having a cavity and a lower portion; a plurality of counter rotating lifting blades extending outwardly and downwardly from the hub to an outer ring, the outer ring having a bottom portion positioned below the lower portion of the hub; a motor mechanism substantially housed within the hub rotates a shaft extending from said motor mechanism, a main rotor secured to the shaft below the lower portion of the hub, and a receiver in communication with the motor mechanism to receive commands for controlling a rotational speed of the main rotor, wherein the rotating toy has a center of gravity positioned above the bottom portion of the outer ring and wherein the main rotor when rotated sufficiently causes the rotating toy to fly; and the remote controller including a transmitter for sending commands to the receiver that control the rotational speed of the rotating toy. 18. The rotating toy of claim 17, wherein the outer ring includes an internal diameter larger than a diameter defined by the main rotor. 19.
