We reconfigured the kit chassis to use pneumatic wheels and did lots of testing with it over the defenses with uneven terrain.
Here it is crossing just an empty platform at roughly full speed with nothing in the way. We unintentionally flipped that drivetrain upside down just once, but it wasn't when going over the rock wall or moat... it was when we went full speed over an empty platform and tried to slow down at the end.
Crossing defenses is very dynamic, CAD doesn't really show whether a design will work or not. Adding pneumatic wheels just makes things even more unpredictable. We weren't at all happy with that 6wd pneumatic setup, we're doing something else.
