Matt,
Sorry I missed talking to you between all the times we were in each other's pit. We are using the same system many teams were using for counting rotations. Two light sensors aimed at alternating reflective/non-reflective spots on the wheel. For those not familiar with the system, two encoders placed such that the outputs are in quadrature (i.e. 90 degrees apart) will allow both direction and tach to be determined. Our sensors do have some limitations but the errors are minimal for the required 15 seconds of autonomous mode. In looking at other teams, we are not entirely unique in looking at the problem or solving it. It seems that at least 20 teams at GLR had a good way to determine length traveled and direction. Many will tell you that non-stacking robots were the rule, but those that did stack were engineering marvels and true crowd pleasers. No doubt about it, GLR is a good (and difficult) regional, no wonder it filled up on the first day. Hope to see you all in Chicago for the Midwest. If you have any questions before you come, drop me a line.
