The software is Mindstorms 1.1 and
the firmware is ver 1.05 . We had tried it with a freshly
charged rechargeable battery pack and got the same results. On the
idea listed previously we just switched to fresh Alkaline Duracells and it is
working ok for now.

Programming/brick problem
Can you tell me what
software and firmware versions you are using that are giving you these
problems?

Ditto,
We have had the same problem.
Sometimes it skips blocks and other times it doesn’t. We verified
it by putting in sound beeps in certain areas and it skipped those beeps and
the movement blocks. We are just going to hope we get one good run when
it doesn’t skip blocks. The overall program is good and the kids
have thought it through. I have no idea why it is skipping blocks and haven’t
found a solution. If anyone finds a solution please post it.

Programming/brick problem
I'm sorry Sherene. I don't have any answers, just to say that our
robot is doing weird things at times too. Like we will run a certain
program and then it just starts skipping steps that are in the program, for
seemingly no reason. It will do that three or four times, then suddenly
start working again. I have no idea. We are getting it to work most
of the time though. It sounds like what you are going through is really frustrating!
I would encourage you to not pull the plug on your team competing though.
That seems unfair to them with all their hard work. The robot game
is only 25% of their total score. They will still be able to talk to the
judges about their robot design and programming, even if their robot does
nothing on the actual table. And they will give their presentation, and
show their teamwork! Good luck, and I hope someone can answer here!

We're having a huge problem with our robot.
the programs are not downloading from the computer to the brick
properly. Despite the message on the computer saying it the program has
uploaded, it is hit or miss if it does.
We're running firmware version 1.28 on Mac OS 10.5.8.
I've done the Mac OS 10.5 firmware fix as indicated here
The programs never run the same way twice. It's like the NXT brick has
a life of its own. We deleted all the programs on the brick and
then downloaded just one of the programs. When we ran the program, it
bore no resemblance to the one we uploaded. Rather, it looked like
another one on the computer that goes by a different name.
I thought to try to reset the brick but for the life of me I cannot
find any reset button. Apparently "The hardware
reset button is located within the LEGO TECHNIC hole below the USB connector on
the NXT brick.".
For the life of me, I cannot find this hole.
If I can't find a solution ASAP, I am going to pull the
plug on the team competing. We cannot waste any more hours trying to fix
buggy Lego equipment.
Can anyone help me? I'm at the end of my tether.
thanks
Sherene
