Question #254443 on Yade changed:
https://answers.launchpad.net/yade/+question/254443

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hi Luis,

O.bodies.append returns list of ids of appended bodies. So 'rod' in your
example has no state (as it is list as the error message says). You can try
e.g.

O.bodies[rod[0]].state.pos[2]

cheers
