[Dprglist] Idea - Line following practice courses

[Clay Timmons]

I was at FedEx dropping off a package and I noticed they have a large format printer.     Aha!  An idea popped into my brain.   Print a small scale test course on the wide paper.   The prices are very reasonable.


I've been working on the line following courses and have tried a couple options for testing at home.    First I make some test courses out of white posterboard and black electrical tape.    I found that electrical tape is difficult to get to nice 6" radius curve and it is very shiny and can easily have bright glare from reflected background lights.    I also borrowed the official club course.    While this is the best for testing it had  a couple drawbacks.   The challenge course is very large and fun to fit that  large cardboard tube into my tiny car.  I also only had one place in my house where I could get the 7'x13' course on a wood floor.

FedEx, Staples,  Office Depot all  offer  "blueprints" /  "architectural" prints in color or black and white in standard sizes including 24"x26" and 36" x 48".    Here are some links.

I plan to design and print some test course on paper.   My idea is not to reproduce the exact DPRG course layout but to print smaller simplified versions for testing purposes.

For the beginner / novice  I'm thinking a simple oval.    If your robot can follow a straight line and a curve with the 6" radius it "should" be able to complete the DPRG course.

For the advanced course I came up with this layout which has all the "elements" of complexity as described in the DPRG line following rules.
Offset,  90 degree,  Gap S,  6" Gap,  Notch.

I'm working on my idea for a simplified version of the challenge course.   The challenge course has many complexities and it will be tricky to get them all into a 36" x 48" course.   For me personally I know where my robot struggles so that is what I really want in a test course.



I just wanted to share my thoughts for any feedback.   I plan to be at RBNO tomorrow evening and would love to have some help on a working out a simplified challenge test course.
I could also use some help laying out the course to get a PDF file for printing.    I used PowerPoint to cobble together my ideas but really need a drawing package like inkscape or adobe.  I have an artist friend who is a whiz with adobe and could knock this out easily but if anyone in the club can help with this let me know.


Cheers,
