I’m considering mounting a second Adafruit BNO085 orientation sensor on a front wheel—possibly on the fender or nearby, instead of a traditional WAS. The goal is to calculate the steering angle by comparing the heading of this sensor to the main BNO085 mounted on the chassis.
Is this approach technically feasible? Are there known limitations or failure modes I should expect?
I got this idea after examining the FJD AT1 autosteering kit, which appears to use a similar method. Can anyone confirm if this is how the AT1 operates?
Tho I spoke to local guys that are selling and mounting FJ Dynamics autosteer and he told me that using a “potentiometer” is 100% more accurate but its harder to mount.
Ah thanks, I searched but did not find that topic. So if I understand correctly, the consensus is that a normal WAS is worth it because it should be much more accurate than an IMU / compass-based solution. Noted!
If the comparison is against whether Trimble uses it or not, AOG should stick with a WAS. Our Trimble is heading for eBay the second I get enough time to put a WAS on the seeder tractor and install AOG. I hate that thing so much.
