Introduction

This, the ninth release of the Toolbox, represents over fifteen years of development and a substantial level of maturity. This version captures a large number of changes and extensions generated over the last two years which support my new book Robotics, Vision & Control.

The Toolbox has always provided many functions that are useful for the study and simulation of classical arm-type robotics, for example such things as kinematics, dynamics, and trajectory generation. The Toolbox is based on a very general method of representing the kinematics and dynamics of serial-link manipulators.

These parameters are encapsulated in MATLAB objects - robot objects can be created by the user for any serial-link manipulator and a number of examples are provided for well know robots such as the Puma 560 and the Stanford arm amongst others. The Toolbox also provides functions for manipulating and converting between datatypes such as vectors, homogeneous transformations and unit-quaternions which are necessary to represent 3-dimensional position and orientation.

This ninth release of the Toolbox has been significantly extended to support mobile robots. For ground robots the Toolbox includes standard path planning algorithms (bug, distance transform, D*, PRM), kinodynamic planning (RRT), localization (EKF, particle filter), map building (EKF) and simultaneous localization and mapping (EKF), and a Simulink model a of non-holonomic vehicle. The Toolbox also including a detailed Simulink model for a quadrotor flying robot.

Advantages of the Toolbox are that:

the code is quite mature and provides a point of comparison for other implementations of the same algorithms;

the routines are generally written in a straightforward manner which allows for easy understanding, perhaps at the expense of computational efficiency. If you feel strongly about computational efficiency then you can always rewrite the function to be more efficient, compile the M-file using the Matlab compiler, or create a MEX version;

since source code is available there is a benefit for understanding and teaching.

Downloading the Toolbox

Download it from here in zip format (.zip).

The Toolbox is tested with MATLAB R2011a.

To install the Toolbox simply unpack the archive which will create the directory (folder) rvctools, and within that the directories robot, simulink, and common.

Adjust your MATLABPATH to include rvctools

Execute the startup file rvctools/startup_rvc.m and this will place the correct directories in your MATLAB path.

Run the demo rtbdemo to see what it can do

To get the MEX version of rne visit the folder rvctools/robot/mex and follow the directions in the README file

Documentation

The book Robotics, Vision & Control (Corke, 2011) is a detailed introduction to mobile robotics, navigation, localization; and arm robot kinematics, Jacobians and dynamics illustrated using the Robotics Toolbox for MATLAB.

The manual robot.pdf is a printable document (around 100 pages). It is auto-generated from the comments in the MATLAB code and is fully: to external web sites, the table of content to functions, and the ``See also'' functions to each other. You can find this in the Toolbox as rvctools/robot/robot.pdf

The Toolbox documentation also appears in the MATLAB help browser.

Support

There is no support! This software is made freely available in the hope that you find it useful in solving whatever problems you have to hand. I am happy to correspond with people who have found genuine bugs or deficiencies but my response time can be long and I can't guarantee that I respond to your email. I am very happy to accept contributions for inclusion in future versions of the toolbox, and you will be suitably acknowledged.

I can guarantee that I will not respond to any requests for help with assignments or homework, no matter how urgent or important they might be to you. That's what your teachers, tutors, lecturers and professors are paid to do.

You might instead like to communicate with other users via the Google Group called which is a forum for discussion. You need to signup in order to post, and the signup process is moderated by me so allow a few days for this to happen. I need you to write a few words about why you want to join the list so I can distinguish you from a spammer or a web-bot.

There is also a frequently asked questions (FAQ) wiki page.

Octave. A large part of release 9 now works with Octave. There is a folder called octave and follow the instructions in the README to install it. The classical Robotics Toolbox functions are supported: Link, SerialLink, Quaternion and all the trajectory, angle conversion functions. None of the mobile robotics functions are covered. In terms of the RVC book the functions for Chaps 7, 8 and 9 are covered.
