What Can I do with LabVIEW?

Odin – 3 rd Place Winner Virginia Tech Powered by LabVIEW and CompactRIO 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

LabVIEW / RIO for Robotics Virginia Tech (LabVIEW + CompactRIO) Do-it-yourself MIT (C with a 40 core Linux cluster) 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

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. As seen on Good Morning America (abcnews) "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."

LabVIEW vs. Text Based Languages

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

Example: Sort 1-D Array C

Black Box

Example: Random Number C

Example: Read Lines from File

Example: FPGA Count Edges VHDL
