Is there any well documented robot interaction language? I would imagine something like taking a user's speech in English, parsing it using some natural language processing like NLTK or Stanford NLP and then building a new sentence understandable by the robot. Does something like this already exists?
I recently found ROILA http://roila.org/language-guide/ but it seems like it is a whole different language and not just a reformulation of sentences using English words with less grammatical complexity.
