Re: AndyMark RAW Box and Potentiometer

Another option is to use the AM String Potentiometer and attach it to the base of your robot and the string to the mechanism: http://www.andymark.com/product-p/am-2674built.htm
So would this be implemented by moving the mechanism towards the switch at the beginning of the match, and then resetting the position of the encoder to 0 when it reaches the switch (because as far as I understand the only information you can get from both limit switches and hall effect sensors is on/off)?
