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.

A cart comprising: a platform configured to support something being transported;a motorized propulsion mechanism;primary wheels including two or more rows of three or more non-swivelable wheels wherein the lower-most points of the wheels in a row form an arc;wherein the primary wheels are disposed on one or more runners extending longitudinally along at least a portion of the platform;wherein the profile of the arc allows the cart to rock on the wheels;wherein the radius of the arc extends above the platform; andwherein one or more primary wheels, each at the end of the two or more rows of three or more non-swivelable wheels, protrude longitudinally past the edge of the platform; andan electronic speed limitation device. 10. The cart of claim 9 wherein the one or more runners are arced. 11. The cart of claim 9 wherein the primary wheels are disposed on a non-arced surface and are attached to the non-arced surface such that the bottom most points of the primary wheels in each row form an arc. 12. The cart of claim 9 wherein the cart is collapsible. 13. The cart of claim 9 wherein the length of the two or more rows of primary wheels spans at least 80% of the cart length. 14. The cart of claim 9 wherein the cart is a personal motorized platform device. 15. The cart of claim 9 comprising an adjustable handle. 16. The cart of claim 9 further comprising an electronic stabilization mechanism. 17. A cart comprising: a platform configured to support something being transported;a motorized propulsion mechanism;primary wheels including two or more rows of three or more non-swivelable wheels wherein the lower-most points of the wheels in a row form an arc;wherein the primary wheels are disposed on one or more runners extending longitudinally along at least a portion of the platform;wherein the profile of the arc allows the cart to rock on the wheels;wherein the radius of the arc extends above the platform; andwherein one or more primary wheels, each at the end of the two or more rows of three or more non-swivelable wheels, protrude longitudinally past the edge of the platform; andan electronic stabilization mechanism. 18. The cart of claim 17 wherein the cart is a personal motorized platform device. 19. The cart of claim 17 comprising an adjustable handle. 20. The cart of claim 17 wherein the cart is collapsible. 21. The cart of claim 17 wherein the one or more runners are arced. 22. The cart of claim 17 wherein the primary wheels are disposed on a non-arced surface and are attached to the non-arced surface such that the bottom most points of the primary wheels in each row form an arc. 23. The cart of claim 17 wherein the length of the two or more rows of primary wheels spans at least 80% of the cart length. 24.
