Davis Creek
First FIRST LEGO League
September 2, 20005


After trying out the Red Rover Red Rover Mars site at Marshall and Davis Creek
these two tried out an idea for FIRST LEGO League 2005.
They programmed in RoboLab and sent the program to the RCX,
Then tried ran the programs.


The final program for the night went forward,
turned left, forward, arm up, backed, turned right, backed, and put arm down.
Mrs. Simon took movies of the progress.

I am trying to figure out why this first activity was so successful.
First there were two very excited kids and very astute parents.
The bot was one that worked for the Aquabots this summer.
I had it set to go forward, lift, back, and put down.
Each of the five programs had the forward and back the time 1 second more.
The hands on goal at the beginning was to find the spot and program that would get the sub returned.
In less than five minutes they had the sub picked up with program 5 that used 5 seconds.
By that time we had gotten out the IR and set up RoboLab.
We actually made a pencil mark on the table to mark the placement of the research vessel.
But we also made a mark for where the bot would start.
I think that having an exact spot for the bot at the beginning was the key to the fast success
for the made up challenge of starting in "base" and getting the sub back.
The steps were taken one at a time to perfection before adding a next step.
The comments "Not satisfied with that" I thought were going to be a problem to the other kid
but instead I came to see that it was leading to continued success.
I showed the parents the tools window to be able to change from wire tool to select to edit tool
but the kids stuck to the short cuts.
I started them out labeling what the first steps did and they just kept it up.
They had not known about ctrl c, ctrl v, and ctrl z. So that was much fun to extend the program.
The right click and replace was used a lot.
I was worried that the instability of the research vessel would cause the bot to be erratic.
The students were unaware of the problem and it never was for them.
