Activate de-lurk and engage.....
I got a RIS recently and am having great fun with it. I am working
with the tank tread robot from the manual trying out the line
following challenge.
What I find is that the bot will move nicely forward and bog down in
turns. One motor will appear to stall. I have looked for any place
the parts may be binding and have found none. I am wondering
if this is just weak batteries. They are down to 7.8V.
How long do you normally get from a fresh set of good quality batteries?
Also, in building a simple two wheel and castor bot as per the instructions,
the robot does not travel in a straight line as the instructions say it
will. Is it possible that I have a bad motor?

I had a similar experience with my new Mindstorms kit, and discovered (by using the RCXCC "Direct Control" options) that, about 10% of the time, one motor failed to respond to start commands (although, if you gave the shaft a starting twist (...)
