Simone Giertz wanted to build and program a robot to feed her breakfast. She bought a robotic arm and taught it to pour cereal, pour milk, and dip a spoon into it and feed her. If you want to try this yourself, she posted a tutorial at Motherboard with all the steps, with photos and more videos.
In retrospect I would probably recommend making a sandwich instead of milk and cereal. That process doesn’t contain any fluids which is preferable when dealing with electronics (and people). Bread is also a great excuse to eat butter.(via Tastefully Offensive)
All in all, preparing breakfast with a robot arm gets 4/10 stars. Messy. Crazy inefficient. Didn’t actually manage to feed me anything. But fun and made me not feel guilty about buying a pretty pricy robot arm.
