FIRST Robotics Competition with CompactRIO and LabVIEW
Application: A controller for the next-generation FRC
   robot control platform.                                                                         Video

Challenge: Providing a flexible, powerful robotics
   design platform for more than 40,000 high school
   students competing in the FIRST Robotics
   Competition (FRC).

Products: LabVIEW, CompactRIO

Key Benefit: By adding CompactRIO and LabVIEW to
   the robotics platform of the competition, we
   increase the technical capabilities of the teams’
   robots while making the programming more
   accessible to a much larger and diverse group of
 "With the CompactRIO controller, we expect students to rapidly design and build advanced robots during
   the six-week build period. The robots they build with this control platform will need to solve complex
      challenges and must be smart, fast, flexible, rugged, and easy-to-program." - Bill Miller, FIRST
