Scientists at MIT's Media Lab in the United States have invented an alarm clock called Clocky to make even the doziest sleepers, who repeatedly hit the snooze button, leap out of bed.

After the snooze button is pressed, the clock, which is equipped with a set of wheels, rolls off the table to another part of the room.
