"Are you a robot?" was a group project from my first year at university. We were tasked with creating a chatbot using the programming language Rivescript.
It didn't have the best outcome as this was pretty much our first time programming but for the start of a chatbot that is designed with no AI and had to have each potential reply programmed.
We based ours off of HAL 9000 from "2001: A Space Odyssey". Type hello/hi/hey to give it a go.
