I have a omnidirectional skid steer drive robot. I am implementing Navigation stack for it. Using default planners and default configuration. Whenever I give a close distance goal to the bot it takes huge turns to correct its orientation and misses the target. What should I do to either make it take sharp turns or disable x velocity while on rotation

  max_vel_x: 0.65
  min_vel_x: 0
  max_vel_theta: 2
  min_in_place_vel_theta: 1

  acc_lim_theta: 5.2
  acc_lim_x: 2.5
  acc_lim_y: 2.5

  holonomic_robot: false
  meter_scoring: true

  xy_goal_tolerance: 0.2
  yaw_goal_tolerance: 0.1

Try adjusting min_in_place_vel_theta default is 0.4 not 1.0, setting at 1 rotates at 1 radian or 57 degrees per second. This parameter sets the minimum rotational velocity allowed for the base while performing in-place rotations in radians/sec.

Thanks! That made some improvement.
