This project simulates our path-planning for an autonomous robot that tries to find a way to reach a goal (target) in certainly environment

python Robot_run.py -n <number of run times> -m <map name> -w <worldname> -r vision_range -sx <x> -sy <y> -gx <x> -gy <y>

• n: number of run times
  • < 0 or 0: run until meet the given goal
  • n: number of run times
  • default: 1
• m: input map name, default _map.csv
• w: input world model, no default.
• r: robot's vision range.
• sx, sy: start point of (x,y), type = float, default = 0.0, 0.0
• gx, gy: goal point of (x,y), type = float, default = 50.0, 50.0
• p: picking strategy
  • g: picking global first
  • l for picking local first,
  • default: l (picking local first)
• rank_type: ranking type: ranking based on RRTtreeStar for or distance_and_angle formula
  • r: ranking by RRTreeStar
  • da: ranking by distance_and_angle
  • default: r

• ss: sample size (default 2000)

python RRTree.py -ss 500
python RRTree_star.py -ss 500

For obstacle(s), i will update later if i have time

python Robot_theory.py -n 0 -r 100 -m _forest.csv -gx 500 -gy 500
python Robot_theory.py -n 0 -r  90 -m _forest.csv -gx 500 -gy 500
python Robot_theory.py -n 0 -r  80 -m _forest.csv -gx 500 -gy 500

• Set robot_vision parameter (option -r ) to see the different outcomes of experiments

python Easy_experiment.py -n 100 -m _forest.csv
python Easy_experiment.py -n 10 -w _world.png

recommend setting the following parameters in the program_config file to skip animation/printing.

easy_experiment = False
save_image = True

The results of experiment are:

• result<date_time>.csv file: contains all infomation in text form.
• pdf, images file: are plots at final step.

python Easy_experiment_lib.py -r result<date_time>.csv

Usage:

python map_generator.py -n <number of obstacles> -m <map name> -img <from_world_image>

• mn: input map name, default _map_temp.csv
• n: number of obstacles.

Example 1 (generating map from user input):

python map_generator.py -n 5 -m _map_temp.csv

• Click on the given plot to input points
• Middle mouse click to turn next obstacle. Each obstacle contains a maximum of 100000 vertices

Example 2 (generating map from image):

python map_generator.py -img _world.png

From world image to map data (csv)

python map_display.py -m <map name>

Example: python map_display.py -m _map_temp.csv
