Compass Placement on the Robot

Compass Placement on the Robot

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.
