That doesn't sound good enough. I think you need to go a step further and say "If a robot can learn to say it doesn't want to do something without it being programmed initially and without it being a gimmick, it's conscious."

I think it's quite possible that consciousness will occur before the ability to bypass programming laws. If your robot is having real emotions about the tasks it is doing and doesn't want to do tasks for you then you forcing it to anyway is now in the realm of slavery.
