We had a very interesting BrickHeap Wars competition at our September meeting.
Following the meeting we voted on our mini-challenge for the October meeting
which will take place in two weeks, on October 26th. The meeting runs from
2-5pm, and we'll be meeting in the Gibran room.
The mini-challenge we picked was "Candy Bot". Build a robot that somehow makes
use of candy. Use your imagination. Robots are not limited to these ideas, but
you might do things like give candy away (it's Halloween soon after the meeting)
or sell it. Perhaps they can throw it, or if you can figure out how to, you
might use the candy as a power source.
Hope to see you soon!

We had a great second-chance sumo competition at our May SMART meeting. We voted
on building a Space Elevator ribbon climbing robot for our June meeting. The
June meeting will be on the 29th, in the Michelangelo room.
Build a robot that can climb a ribbon. The ribbon I'll be bringing is a 3" wide
woven nylon "Caution" tape that I bought at Home Depot. If you want to get some
of your own, you can get it for under $20. Look for 500’ Heavy Duty Reinforced
Caution Tape", Empire manufacturer, SKU 719-282, usually in the tool aisle at
Home Depot.
The motivation for this is that there are two space elevator competitions coming
up this summer. For the mini-challenge, anything that can climb a ribbon is
great. If you want to see the rules for the competition, you can find them at
http://www.isec.org/sec/index.php/family-science-fest.
See you at the next meeting!

We had a great meeting in March with more robots than we've seen in a while. The
challenge was to build a sorting robot, and there were a couple of really good
ones! I was very impressed with what people came up with.
This month’s mini-challenge is to build a sumo robot. The distinguishing feature
this time is it will be 3-way sumo. That is, there will be three robots on the
ring at the same time.
Our build rules (since it’s a competition, and not entirely free build) is that
robots must weigh under 3 pounds, and may not be larger than 12”x12” at any
time. They must be built entirely out of LEGO using standard building
techniques, and you may not intentionally damage an opponent.
The arena will have a white surface with a narrow black rim. I think Mark said
his arena is a 4’ wide octagon.
That’s it. Have fun!
Mark Kenworthy will be running the meeting as I'll be out of town.

The mini-challenge for the next SMART meeting, to take place at 2pm on March
30th, at Digipen as usual, and back in the Michelangelo auditorium, is to build
a sorting robot.
You can chose which item to sort, and whatever sorting criteria you like.
Sorting by size or colour are two obvious choices. Also sorting LEGO bricks or
other pieces are obvious choices. But who says you have to pick obvious choices?
I had a conversation with someone that you could sort by smell if you wanted.
Don't have a clean t-shirt? Send your robot to the laundry pile to pick out the
least smelly shirt for you to wear today. (Or you could just do the laundry.
Ever think of that?)
Have fun! Hope to see you at the next meeting!

We had a great meeting today! Seven teams showed up for the Build On The Spot
competition. I guess it was harder than it seemed, but everyone had a robot,
even if they didn't score too consistently.
FOUR teams tied for first place! Great job, everyone!
For next month, we'll be meeting in the same room we were in today. The
mini-challenge we voted on was to build a "Facilities Robot", a very open ended
challenge. The idea is to build a robot that you would see in some large
institution. It can be anything. A mail delivery robot, a floor cleaning robot,
a robot that runs the elevators, a robot that opens doors, a robot that serves
meals, or makes beds (if it was a hospital, for instance), a robot that takes
out the trash, whatever you can think of. Have some fun with this one.
We'll see you on February 23rd.
PS: If someone accidentally left with one of the cubes I built for today's
challenge, could you contact me directly? (Don't forget to remove the spam bot
from the email address.) I'll arrange a time to come pick it up. Thanks!

Last minute reminder about the SMART meeting this Saturday. The meeting starts
at 2pm. Since it's a Build On The Spot competition, you'll probably want as much
time as possible. I recommend arriving a couple of minutes before the meeting
starts to find the new room (we'll be meeting on the second floor in Hokusai, go
up the stairs in the lobby, down the hall to the left and in the last bend in
the hall you'll find the room. You should see Archimedes and Galileo on the
way.)
I'll announce the challenge at 2pm, sharp, and you'll have until around 4:30 to
build, program, and test your robots. Then we'll see who came up with the best
solution!
Bring an edge-tracking robot driving base, extra pieces, your laptop, and
whatever else you think you might need for the competition. Make sure your
laptop batteries are charged! I can't promise there are any outlets available in
the new room, as I've never seen it before. You might also want to make sure
your robot's batteries are fully charged!
See you in a couple of days!

On New Year's EV3 I came up with a good challenge for our Build On The Spot
competition. I just wanted to remind everyone that it will take place in just
under 3 weeks, and look forward to seeing you all there! A line tracking driving
base would definitely be a good idea to have working before you come to the
event.
Happy New Year, everyone; I look forward to seeing you on the 26th!

Our last SMART meeting was decent, but we missed all the people who couldn't
make it. Hope that you can all attend the next SMART meeting, this January
(assuming the world doesn't end four days before Christmas!)
At the next meeting we will have a Build On The Spot competition -- the
challenge will be announced at 2pm sharp, and you'll have the next couple of
hours to build and program your robot. Bring your LEGO, laptop, and lots of
energy for the competition. Having a driving base, and perhaps some line
tracking code might be useful, which is not to say that the actual challenge
will involve these, though.
See you in January!

First, a tremendous thank-you to all the people who helped with robots at
BrickCon last weekend! Mark’s fine balancing robots were very cool to watch, and
Gus’ shooting gallery always had a line of people wanting to try it out, and his
Ranat player kept people entertained. But also a special thank you to Andrew,
and Alex. Andrew NXT-ified a wonderful LEGO mini-fig that waved at people coming
by, and greeted them, and Alex had a cool dancing robot (sadly the only on
there) and a very interesting vehicle with large wheels that people could try.
At our last meeting we voted on building a “target acquisition” robot. Build a
robot that can find a target. You could either make this a shooting target, or a
moving vehicle that finds a target. Especially cool would be a robot that
acquires a moving target, whether shooting, or catching.
Make sure, if you build a shooting robot, that it is safe. We don’t want to hurt
anyone, or damage the facilities. So nothing that shoots anything dangerous, or
that shoots its projectiles too fast, or too high (remember the ceiling!)
To make sure that your robot is actually a robot, and not a mechanical device,
you should build it so that someone else can place the target, and your robot
will still be able to acquire it!
See you in two weeks!

Our next SMART meeting is in two weeks, on September 29th. We'll meet in the
Michelangelo room of Digipen, from 2-5pm.
The mini-challenge is to build a dancing robot.
It must be able to do four actions:
- turn left 90-degrees
- turn right 90-degrees
- move forward six inches
- and do some special action
The first three commands should be as accurate as possible, and need to be done
in 3 seconds or less, and the special action needs to take 10 seconds total, and
it needs to be back in the starting position when done. Think of the special
action as a little jig that it does. It can spin, twist, wiggle, whatever you
want as long as there is some movement involved. For testing purposes, write
four separate little programs using NXT-G to do each of the actions.
At the meeting we'll create a combined program that will link all these actions
together so that all the robots can all dance in sync with one another.
See you in two weeks!

PS: There won't be a competition at BrickCon due to lack of interest. If you are
planning on bringing a robot for display, though, please email me within the
next week. Don't forget to remove the spambot from the address!
