Hello everybody,
I am the following problem with my robot (rear wheels don't touch the ground):
So I have changed the inertia of my links but I got an error when I change the matrix of some wheels (it's strange because the link in the error message is not linked to the wheels involved in the problem):
> [ERROR] [1453136122.044577471, 24.646000000]: Ignoring transform for child_frame_id "fourche" from authority "unknown_publisher" because of a nan value in the transform (-nan -nan -nan) (0.000000 0.000000 0.000000 1.000000)
Urdf description of my wheels (diameter: 125mm, height: 50mm) :
false
