Intro

• Joe A Varnell – mentor for team 704 SGP Robotics

• Lockheed Martin - Test Engineer – Have been a software and systems

• Worked with NI equipment for 10 years– LabVIEW on and off for 6 years– LabVIEW core I, II, and III

Starting off

To start a new project

Open an existing project

NI Areas for help

Sensor, motor, robot operation examples

The Robot Project

-Give meaningful name to project-Everything under “My Computer” does not-Everything under “RT CompactRIO” goes on the cRIO

-Front Panel-Block Diagram-Flow left to right

-NI Code provides info on diagram-Context Help to see -Double click to dig down into blocks

-Open block going to a refNum register block with meaningful name-Autonomous code-Drag down comment blocks-Dropdowns control operations-Watch dog; Feed the dog

-Get refnum using name-State machine to control execution of teleop-reads joystick and operates on it

-Each loop runs independent of the other (parallel execution)-get reference outside of loop

-Anything outside executes once-Anything inside the loops is repeated
