Description of this data

These are the specifications of each environment used of the manuscript "Motion Planning under Uncertainty in Graduated Fidelity Lattices".

**** ENVIRONMENTS ****
For each environment the following specifications are given. Units are meters and radians:

  • Map dimensions: <DIM_X> x <DIM_Y>
  • Location of the starting pose: (<x>, <y>, <heading>). <heading> = 0 is the direction of the positive X.
  • Goal position: (<x>, <y>)
  • min/max position of the location denied areas: (<x>, <y>)

** FIG 8

  • Dimensions: 40.0 x 24.8 m
  • Starting pose: (5.0, 8.0, 0.0)
  • Goal position: (34.0, 19.0)
  • Location denied areas:
    (6.0, 0.0) to (11.0, 7.0)
    (9.5, 7.0) to (11.0, 8.5)
    (12.0, 11.0) to (28.0, 17.5)
    (13.0, 9.0) to (15.0, 11.0)
    (32.0, 15.0) to (35.0, 20.0)

** FIG 9

  • Dimensions: 65.0 x 40.3 m
  • Starting pose: (4.0, 16.0, 0.0)
  • Goal position: (56.0, 8.0)
  • Location denied areas (9a):
    None
  • Location denied areas (9b):
    (25.0, 0.0) to (52.0, 15.5)
  • Location denied areas (9c):
    (25.0, 0.0) to (52.0, 15.5)
    (25.0, 26.0) to (47.0, 40.0)

** FIG 10

  • Dimensions: 35.0 x 25.3 m
  • Starting pose: (19.0, 20.0, 3.1416)
  • Goal position: (31.0, 5.0)
  • Location denied areas:
    (10.0, 0.0) to (35.0, 25.3)

** FIG 11

  • Dimensions: 30.0 x 30.0 m
  • Starting pose: (7.0, 15.0, -1.5708)
  • Goal position: (5.0, 23.0)
  • Location denied areas:
    None

**** PPM FILE FORMAT ****
Images are provided in the PPM file format (ASCII). These files have the following structure:
# line comment
...
<N_PIXELS_X> <N_PIXELS_Y>
<RGB_VALUE_1>
<RGB_VALUE_2>
<RGB_VALUE_3>
...
<RGB_VALUE_1>
<RGB_VALUE_2>
<RGB_VALUE_3>

This is: after the comment lines (starting with "#"), the first two numbers are the image size (in pixels)
Then, three values for each RGB pixel are given. Pixels follow a row-major order.

Pixels with R < 10; G < 10; B < 10 are considered occupied. Elsewhere is free space.

Please, note that <N_PIXELS_X> <N_PIXELS_Y> contained in these files do not correspond to the dimensions of the
environments in the manuscript. Each pixel has a coordinate (X, Y) which is calculated from the resolution of the image
and the environment dimensions (DIM_X, DIM_Y):
X = PIXEL_X * (DIM_X / N_PIXELS_X)
Y = PIXEL_Y * (DIM_Y / N_PIXELS_Y)

**** OT FILE FORMAT ****
Files to use with the Octomap[1] library are also given. These were generated with Octomap v.1.7.2. These files already have the dimensions used in the experiments and require no additional processing.
