Please let us know how it works out.


a few examples: battery state-of-charge and internal resistance, motor temperature, drivetrain friction
I was able to record an obstacle course on a test bot (this one does drive straight) and it replayed it multiple times on different days with different batteries. I assumed this was a good sign as to its repeatability, but it's possible it won't work as well on the real robot. Obviously it won't be as accurate as a gyro and accelerometer stabilized autonomous, but for what we do (push bin and tote forward into auto zone and turn) it looks to be reliable.
