Two-Stroke, tests cut short by Mother's day commitments.I'm interested in the results of your test run on Sunday. Please keep us posted
As is the Mule has two devices for maintaining a straight cut path. The first a Yaw sensor, second
a USB digital compass, I only tested the compass because after lots of head scratching and lots
of unneeded software changes I discovered the Yaw sensor was interfering with the compass and
had to be removed for this test.
The tests of the digital compass showed it to be a useful but limited sensor, while in a open field
it was able to keep the Mule on a set coarse to +- .3 deg over the 850ft path(Sweet!), but while
in an area with large metal objects(cars, storage sheds, etc..) the Mule could not maintain a
bearing, the objects would change the magnet fields causing the Mule to change coarse(crap!).
an interesting test would be to see if the digital compass could be used to map out the Mule's
environment using magnet fields kinda like an MIR(Magnet Imaging Radar).
