The club-record January signing from Bradford City ended a 10-game goal drought with his third strike for the club in Saturday's 4-2 defeat to Blackburn Rovers.
Robins hopes that the Bermudan will now feel more relaxed in front of goal.
"He is getting to grips with things, and I've been really pleased with his recent performances," the Huddersfield Daily Examiner quotes Robins as saying.
"It's not all about scoring goals, and Nahki has been doing a lot of good work for the team.
"But he's a striker at the end of the day, and I was delighted he scored against Blackburn. You could sense some tension was released when the ball hit the back of the net."
Despite the defeat, Huddersfield look on course to avoid a repeat of last year's final-day heroics as they are 12 points above the bottom three with 10 games left of the season.
