1640 used the Cherry AN8 series absolute non-contact rotary sensors. We have been very pleased with the performance. Note that several teams have had problems with the US Digital absolute encoders. Several teams suspect electrostatic discharge to be the problem. The Cherry sensors are automotive qualified and IP67 rated. Perfect for our robot environment. The availability of the Cherry sensors is spotty and is a problem. Many other companies will be bringing absolute magnetic sensors to the market in the future. Robot teams should watch their development and possible robot applications. The potentiometer is loosing it's place on our robots.
