  1. Agenda • What can I do with LabVIEW? • Why LabVIEW (text based comparison) • Re-visit the State Machine • Intro to common LabVIEW Architectures

  2. A Highly Productive Graphical Development Environment for Scientists and Engineers Hardware APIs Built-In Libraries Custom User Interfaces Deployment Targets Technology Abstractions Programming Approaches G .m

  3. What Can I do with LabVIEW?

  4. DARPA Urban Challenge • Autonomously navigate 60 mile urban environment • Follow all traffic laws • Safely navigate around obstacles/barriers • Safely interact with other UGV and manned vehicles at stop signs during passing, parking Odin – 3rd Place Winner Virginia Tech Powered by LabVIEW and CompactRIO

  5. Do-it-yourself MIT (C with a 40 core Linux cluster) LabVIEW / RIO for Robotics Virginia Tech (LabVIEW + CompactRIO) • NI dramatically reduces the cost of robotics system design, deployment, and testing • Key strengths: • Rapid development software • Extensive, integrated I/O support • Tightly integrated system design platforms • World class support

  6. 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

  7. NASA Mars Rover Robotic Arm LabVIEW Robotics and cRIO for complex mechatronics

  8. Robot-Assisted Laparoscopy with LabVIEW The Challenge:Training doctors to perform robot-assisted laparoscopic surgery using the da Vinci Surgical System (dVSS). The Solution:Using NI LabVIEW to develop a platform to ensure medical students and new surgeons perform robot-assisted laparoscopic surgery using the correct movements to maintain the highest level of patient safety. "The inherent ease-of-use of the LabVIEW platform was enhanced by the numerous training courses offered by NI, which was a component other solutions could not provide." As seen on Good Morning America (abcnews)

  9. LabVIEW vs. Text Based Languages

  10. Benefits and Cons • Black Box scenario • Less flexible (complex) • National Instruments • Lack of Familiarity • Doesn’t feel like a programming language • Shorter learning cycle • Can execute just as fast • UI Integration • I/O Integration • Community • National Instruments • Intuitive

  11. Example: Sort 1-D Array C

  12. Example: Sort 1-D Array Black Box

  13. Example: Random Number C

  14. Example: Read Lines from File

  15. VHDL Example: FPGA Count Edges
