unable to increase speed of the bot using dwa_local_parameter
I am trying to increase the speed of skid steering bot using dwa local planner but the speed doesn't increase above 0.5. I have tried manipulating acceleration, velocity and translational limit in the parameter file but the result is still the same. I don't get what is limiting the bot to not increase the speed above 0.5 m/s.
Update- I checked the situation using
rqt_reconfigure
and the bot is able to react to any value inmax_vel_x
throughout the slider. But when I mention the same values in the yaml file, the bot sticks to 0.5 m/s for vel > 0.5.
Below is the content of my dwa_local_planner_params.yaml

gmapping
anddjikstra
have nothing to do with your question. Thanks.Did you observe
move_base
actually publishing only a maximum velocity of 0.5m/s? Might be something else is limiting the robots velocity as well. Also, please check that the parameters are actually used, i.e. they are loaded in the correct namespace.max_vel_x
andmax_vel_trans
should be the relevant ones. Does changing any parmeter have any effect on the robot? Try setting it to 0.1m/s and see if it is observing this limit. If not, you probably have loaded the parameters in the wrong namespace. Edit your question and show the launch file with which you upload the parameters.Bot is reacting to speed less than 0.5 m/s. But it stays at 0.5-0.55 even if I provide 1.0 m/s.
is this stuff on a repo that we can check? I don't see anything wrong with the configuration, but there are so many things to check that having this on a repo would really help...
