# Mechanum Wheel Demo rosject does not work

I’m trying to launch the “Mecanum wheel demo” rosject launching the roslaunch file unsuccessfully. the robot does not appear on Gazebo once is launched.

I need to study and launch on Gazebo a rosject of a wheeled robot in order to understand how to program a differential velocity controller.

Can you give me some help?
Therefore, can you explain me why the robot does not appear on Gazebo once is launched?
Otherwise, can you suggest me another suitable rosject.

Thank you very much.



Have a look at this rosject: https://app.theconstructsim.com/#/l/3da66040/

roslaunch summit_xl_gazebo summit_xl_omni.launch
rosrun teleop_twist_keyboard teleop_twist_keyboard.py

Itsan over simplification of a omniwheel system, but works as intended in Gazebo
