There was this short animated film (<15 min) I watched once, I think on Youtube, and I'm trying to identify it. It was made relatively recently, most likely within the past decade. The details are:
- A small dinosaur-like robot wakes up in a forest, and explores a post-apocalyptic world where all the humans are gone and everything is overgrown.
- The exploration of the world is interposed by flashbacks to the past, where the robot's inventor is creating a video log about his creation, and his hopes and dreams for it.
- The film ends on a scene where the small robot explores a city and stumbles upon a scene where the overgrown wreckage of a much larger and dangerous-looking version of the small robot is preserved in a scene of combat, with several ancient human corpses around it. Meanwhile, the audio of the scientist's vlog continues, finishing over the scene with the words "Some day, you'll change the world."
