I did a test run in the nice, sunny weather today with the 2015-March-13 APM Rover software.
The navigation refused to work!!! The rover started, seemed to steer but never aimed for the WP:s. I had to fetch it over and over.
Just to test I swished the connectors for the ESCs and let it run. I thought it would circle but it started weaving and moving forwards. Good I thought, then there´s only parameter adjustments but no. Check:
The Rover started driving at the point where it is in the picture. It was weaving in a very long bend to the upper left corner where I caught it and disarmed it. The track back is when I was carrying the rover back to my car. (Home)
As shown i MP it is aiming for WP1 in Auto mode but the path it is following goes somewhere else.
I hope it is my fault so it can be easily corrected.
My setup is 4WD skid steering with 4 brushed 12V motors. Two Graupner Speed Profi 40R powering two motors each. One for each side.
Piksi RTK kit as the first GPS and uBlox as the second.
The Pixhawk has the arrow pointing forwards. The uBlox to.
It seems very, very strange, to me, that the rover run a relatively straight line forward when I switch left and right controllers. Is it possible that Gyro and GPS give conflicting messages?
