Obviously robots are evolving much faster than humans are and will eventually catch up to humans in intellgence but not in those things that make people act stupid like sex, suicide over a "broken heart", suicide over PTSD, laziness.
It is too soon to concern ourselves with the robots taking over. But is important to remember what too look out for. First you would have to see early signs of a revolution where robots would demand the vote for themselves. Before the American Revolution, the British taxed the tea being consumed in America without giving any representation to the residents of America in the governing of the Americans. The Battle cry was "No taxation without representation." So, before the robots rebel, you would have to see someone suggest that robots be taxed. That would signal the beginning of the end.
