Who acts: Lidar, spinning laser, light · What happens: spin, be, measure, time, take, come back · To what, where: spinning laser, distance, 3D picture
This is a sentence of the lesson «Self-driving cars and machines that run themselves» of the technology course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (Lidar, spinning laser, light), what happens, when and where, as Mova's frames read it from the tree.
