 They had a well made scouting form on the bottom was a check box with nothing next to it, when asked what the box was for they said.
"Oh thats the jerk box"
Since then one of our team goals is "Stay out of the jerk box" - Gary Stearns [more] |

Re: Encoders and Rover Wheels
In direct answer, yes, if the wheels slip then the encoder will be wrong. An encoder measures a number of revolutions, and has no way of "knowing" how much traction a wheel has. For traction control, you could look at either an idle wheel, current sensors on the motors, or an accelerometer. Encoders are a good choice to see what the wheels are doing in terms of speed - it will allow comparison to another sensor - and the comparison could provide the slip/no slip info you want.
