Hi

I have installed ROS Melodic, and have noticed that when I send "cmd_vel" commands with a positive sign for the rotational velocity the robot rotates clockwise.... This does not happen in ROS kinetic (Gazebo 7)..

It also affects other nodes such as "move_base",,,

Does anybody knows how to solve this??

I solved it!!!... The reason was that the new version (ROS Melodic https://github.com/ros-simulation/gaz... ) does not support the "legacy mode" tag

" GazeboRosDiffDrive Plugin missing <legacymode>, defaults to true This setting assumes you have a old package, where the right and left wheel are changed to fix a former code issue "

Updating my urdf model fixed the problem!!!
