Everything perfect so far. No sliding around on the dips or the edges of the field, work area is 100% perfect.



It is having the exact same behaviour. Back wheels are losing contact with the ground, and the caster wheels just move it around when they are the only thing that can reach the ground.

Did some messing around, this seems to have worked for the area I am testing.
Main section wheels:
<physics restLoad="4.6" repr="0>0|2|3|1" radius="0.41" forcePointRatio="0.3" frictionScale="2.0" initialCompression="60" suspTravel="0.5" spring="60" damper="50" yOffset="0.095" supportsWheelSink="false"/>
Section wheels:
<physics restLoad="2.6" repr="1>0|1|1|1" radius="0.41" forcePointRatio="0.3" frictionScale="1.0" initialCompression="60" suspTravel="0.5" spring="60" damper="50" yOffset="0.095" supportsWheelSink="false"/>
Caster wheels:
<physics restLoad="2.6" repr="1>0|2" driveNode="1>0|2|1" forcePointRatio="0.5" yOffset="0.045" frictionScale="0" radius="0.16" width="1.25" mass="0.25" initialCompression="40" suspTravel="0.6" spring="55" damper="50" rotationDamping="0.4" brakeFactor="0" versatileYRot="true" supportsWheelSink="false"/>
It acts like the ICtrigger box is the overall collision box. It stops right on the edge of the ICtrigger, and if you move it forward a bit, it keeps moving until it reaches the next pole.
First time I saw any issues was on a turn. Right wide corner, had a pole right in front of it, and the sprayer would stop in the middle of the turn. I just moved the AutoDrive line, and it work without issue.
But when using the route in the image, it kept stopping for every pole it had on it's path.
Mate, have you managed to fix the cart sliding around issue? I'm trying to use it in a map with a few hills, and it does not drive straight, the cart is always crabbing, or sliding the rear, even when stopped.
I messed with a bunch of things, friction, weight, center of mass, cart steering angles etc, but nothing has worked.
