"Make sure the motor leads are open-circuit, not shorted."
If you do... make sure you have created a method of slowing down your minibot before it crashes to pieces on the tower platform...
"Did you use .09 or .094 for the stall torque?"
I used .09.
I usually don't trust the stopwatch for such a short race- too easy to have hidden bias.
A basic 30 fps video camera is easy to get stop and start points estimated to within 30-60 ms based on multiple playbacks and just counting time by single stepping through frames.
And the data is all recorded so someone else can check the calculation.
YMMV... If we can get within 15-25%, I would be VERY happy.
Thanks, Ether, for providing this... The students will have fun with this one.
We are working in New Hampshire...
I noticed you are retired and in "US", which FRC teams did you use to work with?
