This book presents a unified treatment of many different kinds of planning algorithms. The subject lies at the crossroads between robotics, control theory, artificial intelligence, algorithms, and computer graphics. The particular subjects covered include motion planning, discrete planning, planning under uncertainty, sensor-based planning, visibility, decision-theoretic planning, game theory, information spaces, reinforcement learning, nonlinear systems, trajectory planning, nonholonomic planning, and kinodynamic planning. The material grew from courses I taught at UIUC, Stanford, and Iowa State.

Abusing Roomba Robots
We are spending some time determining how to abuse Roomba robots into doing things for which they were not designed. For more information, see our Roomba Lab page.

Rapidly Exploring Random Trees (RRTs)
One of our most successful developments has been the RRT, which is designed for quickly searching high-dimensional spaces for feasible paths. See the RRT Page for more information. Also, see this MATLAB release, game developers article, and blog.

Motion Strategy Library
This is an open-source general-purpose C++ library for implementing and comparing motion planning algorithms, for use in research, education, and industry. See the Motion Strategy Library page.
Recent News: A Windows XP binary distribution is now available on the MSL page, thanks to Wei Wang.

A Nearest-Neighbor Library for Motion Planning
A C++ library, written by Anna Yershova, that uses Kd-trees adapted to topological spaces that arise in motion planning. This enables fast nearest-neighbor computations in sampling-based motion planning algorithms.

Sampling the Space of 3D Rotations, SO(3)
A C++ library, written by Anna Yershova, that generates sequences of samples that are close to uniform and have regular neighborhood structure.
