I can not understand , how can I calculate **max_vel_x , min_vel_x , max_vel_theta and max_rotational_vel** **acc_lim_theta, acc_lim_x** ??
My robot speed value is : 20 cm/sec
so what will I do these parameters for my speed value ?Mon, 07 Sep 2015 02:08:33 -0500https://answers.ros.org/question/217176/base-local-planners-parameters/Answer by allenh1 for <p>hello..

https://answers.ros.org/question/217176/base-local-planners-parameters/?answer=217199#post-id-217199 Those parameters are up to you. These are trial and error parameters. As your robot's speed is `0.2m/s`, I would recommend you start with
`max_vel_x = 0.2`, `min_vel_x = 0.0`. For the others, just try parameters until the planner is working smoothly.Mon, 07 Sep 2015 08:13:19 -0500https://answers.ros.org/question/217176/base-local-planners-parameters/?answer=217199#post-id-217199Comment by osmancns for <p>Those parameters are up to you.
