About

This is an implementation of parts of the paper:
Kinodynamic RRT*: Optimal Motion Planning for Systems with Linear Differential Constraints
by Dustin J. Webb and Jur van den Berg
PDF

If you use the code then I'm sure the authors would appreciate a citation:

@article{DBLP:journals/corr/abs-1205-5088,
    author    = {Dustin J. Webb and Jur van den Berg},
    title     = {Kinodynamic RRT*: Optimal Motion Planning for Systems with Linear Differential Constraints},
    journal   = {CoRR},
    volume    = {abs/1205.5088},
    year      = {2012},
    url       = { http://arxiv.org/abs/1205.5088 },
}

Limitations

  • This implementation does not (currently) solve systems where the matrix A is not nilpotent (see the paper for details).
  • The search radius is not decreased with each iteration (see section V)

Demos

A 2D double integrator

run it using rrt_double_int_2d.m

A quadcopter model with obstacles

use rrt_quad_test.m to run it
waypoints are currently not used (only displayed)
obstacles are rows of 6 values:
(center_x, center_y, center_z, width, length, height)
e.g.

obstacles = [-1,20,-2,   0.5,4,4;
             -3,15,-3.5, 0.5,6,1];
