Dwa_local_planners doubt related to the parameters

Can anyone explain to me the difference between these two parameters used for dwa_local_planner:
/max_trans_vel: The absolute value of the maximum translational velocity for the robot in m/s
/max_vel_x: The maximum x velocity for the robot in m/s.

I mean what’s the difference between the two, I think max_tran_vel should mean compute the net velocity of the robot (I mean sqrt(Vx^2+Vy^2)) and the max_vel_x is the direction of velocity along the x-direction, but, why we need to mention them separately and is there a relation between these values ? or are these params independent of each other? because this doesn’t look like that.

Hello @shravistakashyap,

You can look at this discussion here: https://github.com/ros-planning/navigation/issues/111

Basically, if max_trans_vel is specified, it will use this one. If not, then it will use the independent velocities.
