I've been working with the ADXL202 in a robotics project to measure robot tilt, but preliminary testing has shown that the acceleration of the robot is skewing the ADXL's output. The tilt output has to be accurate within about +- 2 degrees from level, which is no problem with the ADXL when the robot is still. I've heard of accelerometers which don't detect static acceleration fields like gravity, and was wondering if I could use one of those to subtract off the bot's acceleration from the ADXL's output? Has anybody ever done something like this? Couldn't find much on google... Thanks, D -- http://www.piclist.com#nomail Going offline?
