Hello, I have prepared a draft REP for a standard 2D and 3D SLAM interface in ROS [1]. Please give feedback, or provide patches through pull request. This is an official request for the creation of a new REP, I do not know who is responsible for accepting REPs (in REP-1 the contact point is ros-users, in REP-12 it is ros-developers, there should be a REP for reconciliating incompatible guidelines ;) ). Have a nice day, Stéphane [1] https://github.com/stephanemagnenat/rep-mapping-node-api/ -- Dr Stéphane Magnenat http://stephane.magnenat.net
