Another fun lesson learned in robot building. Where to place the compass? I noticed some strange readings today on my Adafruit LSM303. I had already previously discovered that the metal and other electronics of the vehicle was messing with the readings. I dug up a real compass to compare and immediately discovered an easy way to determine the location of interference and best placement. For now, on this vehicle I will put forward of the front wheels. I could also have given it some altitude if I wanted to place it further back. This is fine for now since I’m still just prototyping.
