Is it just me, or does anyone else believe their is something inherently wrong 
with the gears for the new NXT brick, (or maybe it's the new brick itself)?  
Robotics is suppose to be very precise.  Yes, some things go wrong- sometimes.  
But I'll be darned if my team's best consistency isn't 1/3 of the time.  NASA or 
factories would never settle for such horrible ratios.  My team is disheartened 
by the lack of precision in the machinery they are working with.  I can only 
hope that fll come out with a 2.0 gear for their NXT brick by next tournament. 
I'm sad they came out with the new, inconstant model than than sticking with the 
very consistent RCX models and gears.  

Personally, my team is putting their hopes in the skit and teamwork skills.
Regards, 
Brandy

Subject: [VADCFLL-L] NXT merry go round effect


 
 
Our team has a part of its program where the robot is supposed to turn some 
nominal amount (around 30 degrees) and for some reason every 5th run or so, it 
spins about 120  degrees.  They have put a reset motor block, a break block and 
even a 1 sec wait block in front of the errant turn in order to stop the issue, 
but nothing they have done works.  They’ve even tried deleting the block and 
putting another one in.  They thought it was the gearing on the wheels coming 
loose which also causes it to act up, but on the 6-9th run it works fine and 
then at run 10 it does it again.  Well not quite that predictable, but you get 
my point.  Has anyone else had this problem and is there a way to fix it, or 
should the team just be resigned to blow a round at the tournament?  Thanks for 
all the help – this is our first year!
 
Mandy
