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

== Purpose ==

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, [[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.

As the basis of the exercises in several textbooks, the Toolbox is useful for the study and simulation of:<ref>{{cite book|last=Straanowicz|first=Aaron|author2=Gian Luca Mariottini|title=Proceedings of the 4th International Conference on PErvasive Technologies Related to Assistive Environments |chapter=A survey and comparison of commercial and open-source robotic simulator software |year=2011|isbn=9781450307727|pages=1–8|citeseerx=10.1.1.369.3980|doi=10.1145/2141622.2141689|s2cid=247128}}</ref><ref>{{cite journal|last=Nourdine|first=Aliane|date=September 2011|title=Teaching fundamentals of robotics to computer scientists|journal=Computer Applications in Engineering Education|volume=19|issue=3|pages=615–620|doi=10.1002/cae.20342|s2cid=19389930}}</ref><ref>{{cite book|title=Robotics, Vision & Control|last=Corke|first=Peter|publisher=Springer|year=2017|isbn=978-3-319-54412-0|edition=2nd}}</ref><ref>{{cite book|url=http://www.petercorke.com/rvc|title=Robotics, Vision & Control|last=Corke|first=Peter|publisher=Springer|year=2011|isbn=978-3-642-20143-1}}</ref><ref>{{cite book|title=Introduction to Robotics|last=Craig|first=John|publisher=Prentice-Hall|year=2004|edition=3rd}}</ref>

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]]. Robot objects can be created by the user for any serial-link manipulator; 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.

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

==Relationship to other toolboxes==

The Toolbox provides many functions that are useful for the study and simulation of classical arm-type robotics, for example such things as [[kinematics]], [[dynamics]], and [[Trajectory|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]] [[Object_(computer_science)|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 [[Programmable_Universal_Machine_for_Assembly|Puma 560]] and the Stanford arm amongst others. The Toolbox also provides functions for manipulating and converting between datatypes such as: vectors;[[Transformation_matrix|homogeneous transformations]]; [[Roll-pitch-yaw|roll-pitch-yaw]] and [[Euler_angle|Euler]] angles and [[Quaternion|unit-quaternions]] which are necessary to represent 3-dimensional position and orientation.

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.

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|distance transform]], [[D*]], [[Probabilistic_roadmap|PRM]]), kinodynamic planning ([[Rapidly_exploring_random_tree|RRT]]), localization ([[Extended_Kalman_filter|EKF]], [[Particle_filter|particle filter]]), map building ([[Extended_Kalman_filter|EKF]]) and simultaneous localization and mapping ([[Extended_Kalman_filter|EKF]]), and a [[Simulink]] model a of non-holonomic vehicle. The Toolbox also including a detailed [[Simulink]] model for a [[Quadrotor|quadrotor]] flying robot.

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.

Some characteristics of the Toolbox are:

* 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_file|MEX] version;

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