    • The present invention relates to a drifting electric scooter and, more specifically, to a drifting electric scooter, wherein: a sensor unit is installed at a controller and the movement of a scooter is controlled according to the moving direction and angle of the controller, and thus a short control section for acceleration and stopping of a conventional electric scooter is widened, so that the problems, such as abrupt start and abrupt stop, of the conventional electric scooter can be solved; the drifting electric scooter allows riders to more precisely control the speed and enjoy riding such that the riders can easily and safely control acceleration and stopping by simple upward/downward movement of the controller; a human body detection sensor is attached to a handle portion of the controller, and thus the scooter stops to prevent malfunction of the scooter when the controller is separated from a user's hand, so that safety is ensured and thus safe riding is possible; and multiple switches for selecting various riding modes are installed at the controller, so that more pleasant and interesting riding than in conventional scooter riding is possible.

    • A machine and a method for grinding a spacer grid of a nuclear fuel assembly. The machine includes a spacer grid holding unit, a first rectangular coordinates robot for grinding an outer surface of the spacer grid, a second rectangular coordinates robot for grinding a corner of the spacer grid, and a control unit. The spacer grid holding unit includes a holding jig onto which the spacer grid is seated and held, and a rotary index table which is coupled to the holding jig to rotate the holding jig. The first and second rectangular coordinates robots are provided at predetermined positions adjacent to the spacer grid holding unit. The control unit controls the spacer grid holding unit, the first and second rectangular coordinates robots and all programs required to conduct the operation for grinding the spacer grid.
