@priority-kew Do you mind adding a test checking for the limits in
https://github.com/priority-kew/idyntree/blob/export_joint_limits/bindings/pybind11/tests/test_idyntree_model.py#L127
and
https://github.com/priority-kew/idyntree/blob/export_joint_limits/bindings/pybind11/tests/test_idyntree_model.py#L151
?

Note that this might imply you also need to expose hasPosLimits (https://robotology.github.io/idyntree/master/classiDynTree_1_1IJoint.html#af4badbd5891621e847a61d767cffd25e) and getPosLimits (https://robotology.github.io/idyntree/master/classiDynTree_1_1IJoint.html#ab734574da90b6d2ae24169ea180a081b) in the bindings.

The change seems nice, thanks, could you also update the CHANGELOG when you are done? In particular the support for exporting limits in the URDF ModelExporter could be useful also for user that do not use the pybind11 interface.

Ok, I've added tests to python and made a new minor version in the changelog.

See inline comment.

[priority-kew]

Gotcha, yeah I wasn't sure how releases worked.

[traversaro]

Seems good to go to me, what do you think @francesco-romano ?
