 For me, this is the most powerful message of FIRST, that people can come together and work together to achieve so much, and leave old rivalries, grudges, and hard feelings behind. When people talk about culture change, this is what I hope for. - Aren Siekmeier [more] |

Re: Speed Sensors
Probably you want an encoder. Accelerometers can be used, but tend to have more error than encoders (both because use must integrate acceleration from it to get velocity, and because accelerometers tend to get a decent amount of noise in their output).
Many teams use the Greyhill encoders that can be obtained from Digikey. Another available for encoders this year is to buy the encoders designed to hook right up to the Banebots kit transmissions (available at the Banebots website). |
