Adam Clayton's 85th minute goal sealed victory for the Terriers and hit the Latics play off hopes in the process.
"I am delighted with the win because the conditions were so tough," said Robins.
"At times it looked like no one had played the game before but I thought what quality there was on show came from us. The game was just strange and surreal and the conditions dictated it.
"For a long time it looked like it would be a mistake that settled the game, and a goal would go in off the back of someone's head or their backside."
"We have beaten a good side in Wigan. They are one of the teams who will be in the shake-up come the end of the season."
The result sees Huddersfield move within three points of the Latics whils Uwe Rosler's side remain seven points away from the playoffs with two games in hand.
