You ask either of the robots "What would the other robot say if I asked it which is the door to freedom?"

If you as it this question, you will get the same answer from either robot. This is because the truth robot would want to tell you the truth, but because the other robot lies, it would have to lie too.
If you asked the liar robot this question, he knows that the other robot would tell the truth but he would lie.
So if you asked either robot that question, they would both point to the door to certain death.
