Huddersfield have now gone five without victory, and Robins says that his players are making it too easy for their opponents.
"Another day in the football factory and a few more mistakes. It's one of those things you can't legislate for," Robins told reporters.
"We've got to expect them making mistakes. When we give them a chance we really give them a chance.
"I thought the game generally was a decent game of football and we've just gifted them two goals. All season I have said we have got to take the mistakes on the chin."
Huddersfield are 16th in the league table.
