The pressure is on for these LEGO robots, and the tech-savvy middle school students who created them.

"I feel pumped up I mean, we're the best of the best," said one student.

The best in New York City, and possibly the world. 

IS 192 in St. Albans won the F.I.R.S.T. LEGO League Citywide Robotics Contest.

Now, they're preparing for an international championship in St. Louis, Missouri. 

"We're putting our A-game on right not we're working like 110% right now," said a second student. 

The competition is organized by non-profit NYC First. 

The goal is to get students to pursue careers in science, technology, engineering, and math. 

"We sketch our ideas, and we also virtually design everything we do before we do it," said a third student. 

This years theme is 'Trash Trek.'  Students program their robots to complete various tasks focused on recycling.

The competitors also have to identify a trash-related issue, and propose a way to solve it.  I.S. 192 students discovered recycling machines frequently jam. 

"So their solution was to add color to the bar codes that the bottles read, and that way the machines wouldn't break down as much," said Eric Greene, who is a Robotics & Technology teacher.

The students are also judged on the league's core values including teamwork, professionalism and cooperation. 

"These kids, there's something magical about these kids, they wouldn't settle for mediocre, every time they were working good enough was not good enough it had to be excellent," said Greene. 

"It is really competitive you have teams from all over the world, and we're in it to win it like, serious," said another student. 

But they still make time for fun. 

The team has set up an online fundraising page for the trip.

The World Championship starts on April 27.
