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.

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
