The Goal To Work Towards:
The Goal To Work Towards:
First Technical Challenge(FTC) provides a new and unique goal each and every season. Fundamental building blocks are always applicable and teams can develop experience.
http://www.usfirst.org/roboticsprograms/ftc/registration
For training it works well to have one complete robot set per group of (2-5) students. Note that there is a maximum of 10 students on an FTC team(Grimsley runs 2 FTC teams to support the student interest base)
FTC Competition is 2 vs 2, so 4 sets allow a complete scrimmage match.
There are classroom packs available which are geared towards curriculum integration.

The programming environment
The programming environment
Two options, Labview and RobotC, both have merit and benefits.
A site license for Labview for Lego Mindstorms is a reasonable cost. Labview is a graphical programming language that is easy for anybody to understand and get started quickly. Labview is used professionally in automation and data collection environments. Labview does not handle complex loop structures well and can make advanced logic function difficult to read and follow. Grimsley has used Labview because:
Labview is a fully functioning, industry used language
National Instruments provides a tremendous amount of support for FRC
National Instruments makes the brain of the FRC control system which is primarily designed to work with Labview(But works well with Java and C++ also)
There is little to no “syntax” to learn with Labview therefor a low barrier to entry for newcomers without previous programming experience
The level of abstraction is appropriate, but not restrictive. It’s easy to get complicated functions working with the provided building blocks, but the Labview environment allows digging in deeper if desired
Robotic control concepts in Labview The slides use an older version but the concepts are still very useful.
Robot C is the second programming language.
Well supported traditional text based language
Good tools and getting started guides
More readily transferable to future programming language since the students must learn to debug line code
Easier for Mentors to spot simple logic or syntax mistakes
Not as easy for newcomers to pick up and run with, but a really great introductory environment
How to get there:
How to get there:
Mechanical advantage(Leavers, pulleys, gears) and structural building blocks are key principles that should be learned.
Work through this curriculum, emphasizing the principles more than the outcome. http://www.tetrixrobotics.com/GettingStartedGuide/intro.htm
