move_base doesn't publish good /cmd_vel in real world

Hi, I am having problems to get the correct /cmd_vel published by the move_base node when running the robot in the real world, it shows like a PWM signal. However, when running the gazebo world it works perfectly fine, I have no idea why is it but the code is the same for both, could it be because of the /clock topic that the move_base subscribes when running gazebo but not in real. https://ibb.co/XJZ2h0V https://ibb.co/MN1x36P I am using ros melodic en ubuntu 18

Is it possible there are multiple nodes publishing to /cmd_vel? You can check with rostopic info /cmd_vel. Otherwise, it would be helpful to see your launch/log file(s).
