No one has mentioned the Bluetooth wireless link that is missing from the
educational versions!  Unless someone can explain how to find this feature
in the educational versions of the software, I would highly recommend buying
only the retail version.  While wireless is not permitted during competition
it is a very valuable feature while teaching and during the program
development phase.  Not only can programs be very quickly downloaded without
plugging in the bot, this bi-directional wireless link can also be used to
read motor positions and sensor values from a live robot.  For example, you
can move the arm and read exact number of degrees of rotation.  Then plug
that value into your code and you are done.  No more time wasting
iterations.  This can work for wheel rotations too.  You can also read
sensor values to determine what the robot is sensing, in real time!

 

I feel Lego's decision to delete this wireless feature from the educational
version was a big mistake.

Wendy,

 

Nice summary. Attached is part of a presentation that I put together. This
particular slide helps summarize the same information in a matrix for easier
comparison. 

As you mention, the biggest differences in the kits are:

.        Color sensor vs. Light Sensor

.        Batteries

.        Included?

.        Rechargeable?

.        Software license

.        None

.        Single Seat

.        "FLL Team License"

 

Also, this blog, from Northern California, discusses the differences:

Thanks,

Bill

Below is information I sent to some friends a while back.  The product
number for the Resource set changed & prices went up, so the differences
listed below may not be exact,   but generally speaking  FLL Robot set =
Retail kit (8547) + Resource Set (9695) with a few differences...

____________________________________________________________________________

The "FLL Robot Set" consists of:  

LEGOR  MINDSTORMSR Education NXT Base Set Product ID: W979797

LEGOR  MINDSTORMSR Education Resource Set   Product ID: W979695

set/2214>

LEGOR  MINDSTORMSR Education NXT Software

re_2_1/2240

(Purchasing thru FLL provides the FLL Team license )

 

 

The retail kit (8547), which you find on the web for $250-$270, is
essentially the NXT Base Set above with just a few differences as follows:

Retail kit does not come with the rechargeable battery.

Retail kit has color sensor.  The Education set has just plain light
sensors.

Retail kit comes with the software, but not the license for loading it on
many computers as you would need in a school setting. 

I think the retail kit did not have the sound sensor either???   I could be
wrong.

I think the retail kit has fewer tire choices. 

The retail kit does not have the red and blue plastic balls either (minor
difference)

 

The retail set (8547)   +   the Education Resource Set above (9648) (~$80)
is a close equivalent to the "FLL robot set" with differences listed above.

 

Hope this helps.

I had another rookie team question. We bought the NXT kit from Amazon this
summer.

 

What is difference between this Kit and NXT kit supplied by FLL.  Do we need
to buy more parts ?

Do you mean that you just started your team and are registered for a local
tournament?  Because competition is just 2 to 3 weeks away, and that's a
pretty tall order. But good luck to you and your team. 
        If it were me and I had just started, I would not enter into this
year's competition, but hold an after school program starting in January
every other week, teaching them programming and then enter next fall's
tournament.  Definitely go to this year's event, even as a spectator,
because being at the competition teaches you a lot. 
     As for books to teach lego to your team,. I highly recommend Educate
NXT 
http://www.educatenxt.com/
It's the best value for your money and time.  Carnegie Mellon also has an
excellent series called Robotic Engineering.  They started a free online
class equivalent but I can't seem to find that link right now;  Maybe
someone else has that link.

I was a thinking a good book will be a nice way to get a jump start for our
team.
I see a bunch of books available in Amazon.  Any suggestion ?
