Hi, can someone help please. I'm looking to build a novel, spinning robot (~300rpm) and need a means of getting an angular position with repect to the earth. Thinking spinning guro, piezo gyro, magnetometer etc. Does anyone have some suggestions, ideas. I've hit a block in that most sensors I've looked at are limited to a max speed of around 200 deg/s - not enough! Thanks karl skinner -- http://www.piclist.com#nomail Going offline?
