Petitcat calibrates his intuitive physics engine

Petitcat calibrates his "intuitive physics engine in the head" by playing with a dot on the floor.
As before, he has a hard-coded reflex to withdraw when he detects a black shape on the floor that prevents him from escaping his arena and from falling when he is on a table. His "eyes" are not cameras but a sonar: he cannot "see" the black shapes but only "feel" them with his luminosity sensors when he passes over them. The sonar detects objects in the surrounding that somehow distract him but he manages to keep his attention on the black dot.
Top right: his internal egocentric memory. Bottom right: his allocentric memory in the reference frame of the black dot.
Watch the color LED throbbing on his back (also represented as a small square on his back in the memory views).
At the beginning, the LED is green meaning that he is happy and explores the world.
TC 0:04, he stumbles upon the black dot, the LED becomes white meaning that he is feeling playful and plays with the black dot. TC 0:37, he looses the black dot, the LED turns red meaning that he becomes vigilant and searches for it. TC 0:42, he finds the dot again and the LED returns to white. TC 2:10, he has enough playing, the LED turns green again and he happily leaves for new adventures.
