Our team is using a 2 yr old mindstorm's brick and an education version
brick purchased this year. Both have firmware 1.31 downloaded and both are
running on AA batteries (refreshed at the same time.) We notice a
difference in how programs are being executed- I don't think the problem in
this case is related to motor differences. For example, one brick will
execute a 90 deg turn and run a loop driving forward until the ultrasonic
makes it stop. The other brick seems to be jumping the loop - by this I
mean it seems that while executing the turn, the ultrasonic sensor is
activated and triggering a stop before the robot has driven forward.

Are there any other software differences I might have overlooked? Both were
running the same program written in the education disc downloaded program.

The other variance we've seen is within loops- One robot will stay straight
with a continuous loop, whereas the other has significant drift. I am
willing to attribute that to motor differences, but would love to hear any
other thoughts.

Thanks
