This does not appear to be a recognized English word in standard dictionaries.
This appears to be a non-standard or fabricated form, possibly combining 'automaton' with pluralization or Latin endings, but no established usage exists in English linguistic or technical references.
When you encounter words that don't exist, it's a reminder that language evolution happens through consensus—if enough people started saying 'automatonta,' it might eventually become real, just as 'selfie' went from made-up to dictionary-standard in a decade.
