The '''Robotics Toolbox''' is [[MATLAB]] Toolboxtoolbox software that supports research and teaching into arm-type and mobile [[robotics]]. While the Robotics Toolbox is [[free software]], it requires the proprietary [[MATLAB]] environment in order to execute. The Toolbox forms the basis of the exercises in several textbooks.

== Purpose ==

This is [[free software]] but requires the proprietary [[MATLAB]] environment in order to execute. A subset of functions have been ported to [[GNU Octave]].

The Toolbox provides functions for manipulating and converting between datatypes such as: vectors;, [[Transformation matrix|homogeneous transformations]];, [[roll-pitch-yaw]] and [[Euler angle|Euler]] angles, and[[axis-angle representation]], [[Quaternion|unit-quaternions]], and [[Screw theory#Twist|twists]], which are necessary to represent 3-dimensional position and orientation. It also plots coordinate frames, supports [[Plücker coordinates]] to represent lines, and provides support for [[Lie group]] operations such as logarithm, exponentiation, and conversions to and from [[skew-symmetric matrix]] form.

The Toolbox forms the basis of the exercises in the textbooks.

*Classical classical arm-type robotics: [[kinematics]], [[Dynamics (mechanics)|dynamics]], and [[Trajectory|trajectory generation]]. The Toolbox uses a very general method of representing the kinematics and dynamics of serial-link manipulators using [[Denavit-Hartenberg parameters]] or [[Denavit–Hartenberg parameters#Modified DH parameters|modified Denavit-Hartenberg parameters]]. These parameters are encapsulated in [[MATLAB]] [[Object (computer science)|objects]], . robotRobot objects can be created by the user for any serial-link manipulator and; a number of examples are provided for well known robots such as the [[Programmable Universal Machine for Assembly|Puma 560]] and the Stanford arm amongst others. Operations include [[forward kinematics]], analytic and numerical [[inverse kinematics]], graphical rendering, manipulator Jacobian, [[inverse dynamics]], forward dynamics, and simple path planning. It can operate with symbolic values as well as numeric, and provides a [[Simulink]] blockset.

*Ground robots and includes: standard path planning algorithms (bug, [[distance transform]], [[D*]], and [[Probabilistic roadmap|PRM]]), lattice planning, kinodynamic planning ([[Rapidly exploring random tree|RRT]]), localization ([[Extended Kalman filter|EKF]], [[particle filter]]), map building ([[Extended Kalman filter|EKF]]) and [[simultaneous localization and mapping]] (using an [[Extended Kalman filter|EKF]] or graph-based method), and a [[Simulink]] model of a non-holonomic vehicle.

* Flying [[quadrotor]] robots, and includes a detailed [[Simulink]] model.

The Toolbox requires [[MATLAB]], commercial software from [[MathWorks]], in order to operate.

==Relationship to other toolboxes==

The Robotics System Toolbox for MATLAB<ref>{{Cite web |title=Robotics System Toolbox |url=https://www.mathworks.com/products/robotics.html |access-date=2022-07-23 |website=www.mathworks.com |language=en}}</ref> is proprietary software published by [[MathWorks]] which includes support for robot manipulators and mobile robotics. Its functionality significantly overlaps that of the Robotics Toolbox for MATLAB but the programming model is quite different.

The Robotics Toolbox for Python is a reimplementation of the Robotics Toolbox for MATLAB for Python 3.<ref>{{Cite book |last1=Corke |first1=Peter |last2=Haviland |first2=Jesse |title=2021 IEEE International Conference on Robotics and Automation (ICRA) |chapter=Not your grandmother's toolbox – the Robotics Toolbox reinvented for Python |date=2021-05-30 |chapter-url=https://eprints.qut.edu.au/229002/1/107291254.pdf |___location=Xi'an, China |publisher=IEEE |pages=11357–11363 |doi=10.1109/ICRA48506.2021.9561366 |isbn=978-1-7281-9077-8|s2cid=239037868 }}</ref><ref>{{Citation |last=Corke |first=Peter |title=Robotics Toolbox for Python |date=2022-07-23 |url=https://github.com/petercorke/robotics-toolbox-python |access-date=2022-07-23}}</ref> Its functionality is a superset of the Robotics Toolbox for MATLAB, the programming model is similar, and it supports additional methods to define a serial link manipulator including URDF and elementary transform sequences.

The Toolbox provides functions for manipulating and converting between datatypes such as: vectors;[[Transformation matrix|homogeneous transformations]]; [[roll-pitch-yaw]] and [[Euler angle|Euler]] angles and [[Quaternion|unit-quaternions]] which are necessary to represent 3-dimensional position and orientation.

== Use of MATLAB ==

MATLAB is a commercial software by Math Works Inc., USA. It has large number of mathematical operators and commands that can perform wide range of analysis, e.g. matrix operations. algebraic and differential equation solutions, optimisations, control experiments, etc.

=== Initialise MATLAB ===

It is expected that MATLAB is installed in a computer where the user will be performing computations. If an icon is available on the Desktop the user has to double-click on it using the left button of the mouse connected to the computer. Alternatively, the user can left-lick. in sequence, on the button/menus that popup: Start -> All Programs -> Matlab-> MATLAB.

=== How to Use MATLAB ===

When MATLAB software starts. the MATLAB screen appears with ">>" prompt. This window is called MATLAB command window. Some basic operations are shown here. For detailed description, one may refer to the books available on MATLAB, e.g. Pratap (2002), and use the Demos and Help menu of the software.
