Maybe not useful (to anyone else at least), but I've built a couple of small wheeled robots with cameras to do some experiments with Computer Vision. Unless you're doing computationally intensive tasks, I find a Raspberry Pi 3 is overkill. If you go with the cheaper models like one of the low end Orange Pi's, you don't mind dedicating them to projects, even if the project is pretty useless.
