check_path logic

[oceanfly]

Hello!

I am trying to understand the logic of checking path:

From (-0.3, -0.58, 1.57) to (0,-0.58,1.57), check_path is successful:

[INFO] [1607361215.408972]: start pose: x -0.300000, y -0.580000, theta 1.570000
[INFO] [1607361215.409855]: goal pose: x 0.000000, y -0.580000, theta 1.570000
[INFO] [1607361215.410726]: check_path requested from 'Point2D(-0.30, -0.58), theta: 1.57' to 'Point2D(0.00, -0.58), theta: 1.57'
[INFO] [1607361215.468045]: check_path succeeded

However, just From (-0.3, -0.58, 1.57) to (0.1,-0.58,1.57), check_path is not successful:

[INFO] [1607361415.854583]: start pose: x -0.300000, y -0.580000, theta 1.570000

[WARN] [1607361415.918201]: check_path failed: NO_PATH_FOUND

I am not sure why it is like that. Could you please provide some suggestions ? Thanks!
