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. Furthermore, we provide ROS C++ and Python version.

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
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");
