  1. LabVIEW for FRC Long Island Software Workshop Dec 13, 2008 Robert.berger@ni.com

  2. Agenda • Intro to the New Control System • LabVIEW Basics • little LabVIEW History • What else LabVIEW might be able to do for you • Resources • Hands On Instruction • LabVIEW Project Window • WPI Robotics Libraries for LabVIEW

  3. What is LabVIEW? • It is a tool used by scientists and engineers to measure and automate the universe around us • It is a graphical programming environment • programming – it is a programming language and you won’t be an expert in a day or two • graphical – you draw your code • environment – it is more than measurement and automation, it has analysis and user interface capabilities created for scientists and engineers

  4. Virtual Instruments (VI) • LabVIEW = Laboratory Virtual Instrumentation Engineering Workbench • Programs are called VIs (vee-eyes), they have: Front Panel Block Diagram

  5. VI / Car Analogy – Front Panel • The Front Panel is like the driver’s cockpit • Controls or Inputs to the car • Ignition Key, Shifter, Gas Pedal, Brake, etc. • Indicators or Outputs • Speedometer, Tachometer, Fuel Gauge, etc. • Connects to the engine compartment

  6. VI / Car Analogy – Block Diagram • The Block Diagram is like the engine compartment • Functional Blocks • Engine, alternator, battery, sensors, control modules, etc. • Wires, Tubes and Hoses • Connects everything together • Connects to driver’s cockpit

  7. LabVIEW History • 1986 - Premiered on a Macintosh • It mainly automated electronic instruments – oscilloscopes, multimeters, etc • 1992 - Ported to MS Windows • 1997 - Ported to a Real Time OS • Used by several Universities and Companies in various robotics competitions • VA Tech started using it in 2003 – They finished in 3rd place at the Urban Grand Challenge – late 2007 • 1999 - Robolab was introduced by LEGO & Tufts Univ • 2006 - Ported to run on a LEGO MINDSTORMS NXT • 2008/9 – LabVIEW FTC and FRC

  8. Other LabVIEW uses • Students • Students Projects with LEGO NXT • You’ll see it in many collegiate engineering & science programs • Create NXT-G blocks for your favorite FLL or FTC team* • Teachers • Project Lead the Way • The Infinity Project • Works with your Vernier Sensors • * You’ll need LabVIEW Version 7.1

  9. Other LabVIEW uses • Mentors from Industry • Instrument Control – GPIB, Etc • Industrial Automation – PLCs, HMI, SCADA • Machine Vision • Motion Control • Program FPGAs • Embedded Targets – ADI Blackfin, ARM 7 • Algorithm Engineering

  10. Early Virginia Tech (TORC) successes using LabVIEW in Autonomous System Projects Results of IGVC Competition 1996 –- Did not place 1997 –- 5th place 1998 –- Did not place 1999 –- 7th place 2000 –- 1st place 2001 –- 2nd place 2002 –- Did not place Introduction of LabVIEW 2003 -– 1st Place 2004 –- 1st Place 2005 –- 1st Place 2006 –- 1st Place 2007 –- 1st Place http://www.igvc.org/

  11. Resources • Books • LabVIEW for Everyone – Travis & Kring • Learning with LabVIEW – Robert Bishop • LabVIEW for LEGO MINDSTORMS NXT - Michael Gasperi • Websites • ni.com/first

  12. Logistics • LabVIEW for FRC • 2 DVDs ship with the Kit • You don’t need to load both • Disk 1 = LabVIEW • Disk 2 = Windriver C++ • Version 8.5.1 which is not the latest version • http://www.usfirst.org/frccontrolsystem • LabVIEW FRC software update - VERY IMPORTANT • Control System Manual • H/W and S/W Documentation • If you don’t have your kit – use LabVIEW Evaluation Copy

  13. Hands On Instructions • At first, please do what I do… don’t stray • Listen Carefully… • “left-click” vs. “right-click” • “click & release” vs. “click & hold” • Raise your hand … shout “Help!”
