What parameter in the navigation package controls the arc or straightness of a path? Currently it creates an undesired curve or arc to reach a goal. Looking to make straight lined paths towards a goal.

This could depend heavily on the local controller used as part of your navigation setup. Which controller / local planner are you using?

I think You can try changing the following parameters.

Adjust path_distance_bias, goal_distance_bias, and occdist_scale. In particular, it is recommended to increase the path_distance_bias.

Make acc_lim_th smaller. It will reduce the possibility of selecting a curve. Note that this will also reduce the selection of curves under normal conditions.
