# Introduction
`Motion planning` plans the state sequence of the robot without conflict between the start and goal.
`Motion planning` mainly includes `Path planning` and `Trajectory planning`.
* `Path Planning`: It's based on path constraints (such as obstacles), planning the optimal path sequence for the robot to travel without conflict between the start and goal.
* `Trajectory planning`: It plans the motion state to approach the global path based on kinematics, dynamics constraints and path sequence.
This repository provides the implement of common `Motion planning` algorithm, welcome your star & fork & PR.
This repository provides the implementation of common Motion Planning algorithms. The theory analysis can be found at [motion-planning](https://blog.csdn.net/frigidwinter/category_11410243.html). Furthermore, we provide [ROS C++](https://github.com/ai-winter/ros_motion_planning) and [Python](https://github.com/ai-winter/matlab_motion_planning) version.
# Quick Start
The file structure is shown below
```
├─gif
├─examples
│ ├─simulation_global.mlx
│ ├─simulation_local.mlx
│ ├─simulation_total.mlx
├─global_planner
│ ├─graph_search
│ ├─sample_search
│ └─evolutionary_search
├─local_planner
└─utils
```
The global planning algorithm implementation is in the folder `global_planner` with `graph_search`, `sample_search` and `evolutionary search`; The local planning algorithm implementation is in the folder `local_planner`.
To start simulation, open `./simulation_global.mlx` or `./simulation_local.mlx` and select the algorithm, for example
```matlab
clear all;
clc;
% load environment
load("gridmap_20x20_scene1.mat");
map_size = size(grid_map);
G = 1;
% start and goal
start = [3, 2];
goal = [18, 29];
% planner
planner_name = "rrt";
planner = str2func(planner_name);
[path, flag, cost, expand] = planner(grid_map, start, goal);
% visualization
clf;
hold on
% plot grid map
plot_grid(grid_map);
% plot expand zone
plot_expand(expand, map_size, G, planner_name);
% plot path
plot_path(path, G);
% plot start and goal
plot_square(start, map_size, G, "#f00");
plot_square(goal, map_size, G, "#15c");
% title
title([planner_name, "cost:" + num2str(cost)]);
hold off
```
