This is the home page of the textbook "Modern Robotics: Mechanics, Planning, and Control," Kevin M. Lynch and Frank C. Park, Cambridge University Press, 2017, ISBN 9781107156302. Purchase the hardback through Amazonor through Cambridge University Press, or check out the free preprint version below.
If you find this book useful for a course or self-study, please contact Kevin or Frank and let us know!
From the foreword:
"Frank and Kevin have provided a wonderfully clear and patient explanation of their subject." Roger Brockett, Harvard University
"Modern Robotics imparts the most important insights of robotics ... with a clarity that makes it accessible to undergraduate students." Matthew T. Mason, Carnegie Mellon University
This book is the result of course notes developed over many years for the course M2794.0027 Introduction to Robotics at Seoul National University and ME 449 Robotic Manipulation at Northwestern University. The evolving course notes have been posted on the internet for years to support these classes.
The for-purchase version of the book from Cambridge University Press has improved layout and typesetting, updated figures, different pagination (and fewer pages), and more careful copyediting, and it is considered the "official" version of the book. But the online preprint version of the book has the same chapters, sections, and exercises, and it is quite close in content to the Cambridge-published version. The current, and final preprint, online version of the book is dated May 2017. We posted preliminary versions of the book in October and November 2016; those versions should be discarded.
We are posting four versions of the book. All versions have exactly the same contents and pagination. They differ only in the sizes of the margins and the size of the print, as manipulated in Adobe Acrobat after latex'ing. Two of the versions have working hyperlinks for navigating the book on your computer or tablet.
With working hyperlinks. (To navigate the book using the hyperlinks, click on the hyperlink. To go back where you came from, choose the button or keystroke appropriate to your pdf reader. For example, on the Mac with Acrobat or Acrobat Reader, use cmd-left arrow. With Preview on the Mac, use cmd-[. Some readers on other operating systems use alt-left arrow. You can google to see which solution works for your pdf reader.)
- Default 8.5x11 or A4 version. Printable version with 10 pt font and large margins.
- Tablet version. Margins have been eliminated so that no space is wasted when viewing the document on a computer or tablet.
Without working hyperlinks.
- Large font 8.5x11 or A4 version. Printable version with 12 pt font equivalent and smaller margins than the 10 pt default version.
- 2up version. Printable version with 2 book pages per page, for saving paper if you have good eyes. Approximately 8.5 pt font equivalent.
These files have been compressed to about 7 MB. Let us know if you have any problems reading them. Please note that recent versions of the default Mac OS X pdf reader, Preview, are known to have some bugs displaying certain images in pdf files. If a figure is not appearing properly, please try a better pdf viewer, like Acrobat Reader.

You can see an excellent collection of robotics videos at the Springer Handbook of Robotics Multimedia Extension. Also check out the Robot Academy at Queensland University of Technology.
If you are an instructor, you can obtain a copy of the exercise solutions from Cambridge University Press. Go to the "Resources" section of the Cambridge University Press webpage for the book.
This book was written to be accessible to engineering students after taking typical first-year engineering courses. The student should have an understanding of:
- freshman-level physics, including f = ma; free-body diagrams with masses, springs, and dampers; vector forces; and vector torques (or moments) as the cross product of a distance vector and a force;
- linear algebra, including matrix operations, positive definiteness of a matrix, determinants, complex numbers, eigenvalues, and eigenvectors;
- some calculus, derivatives, and partial derivatives; and
- basic linear ordinary differential equations.
The student should also be prepared to program, but only basic programming skills are needed. Code is provided in python (freely available), MATLAB (for purchase, or you could use the freely available GNU Octave clone), and Mathematica (for purchase), so those languages are preferred.
We welcome your comments and corrections! Please click here to report any corrections for the book. (Please make sure you are using the print version of the book or the May 3, 2017, online version of the book.)
The software accompanying the book is written in Mathematica, MATLAB, and Python. It is written to be educational and to reinforce the concepts in the book, not to be as computationally efficient or robust as possible.
The origin of the software is student solutions to homework exercises. A major update was committed in January 2017, correcting some bugs in the earlier version.
We have found the V-REP robot simulation environment to be a valuable learning tool accompanying the book. It is free for educational use and cross platform. In ME 449 at Northwestern, we use it to experiment with the kinematics of different robots and to animate solutions to inverse kinematics, dynamic simulations, and controllers.
This page gets you started with V-REP quickly.
This page provides "scenes" that allow you to interactively explore the kinematics of different robots (e.g., the Universal Robots UR5 6R robot arm and the KUKA youBot mobile manipulator) and to animate trajectories that are the results of exercises in chapters on kinematics, dynamics, and control.
- A video of a UR5 trajectory created by solving numerical inverse kinematics (Chapter 6, Inverse Kinematics)
- A video of the UR5 falling under gravity for 10 s, assuming no friction or gearing at the joints (Chapter 8, Dynamics of Open Chains)
- A video of the KUKA youBot mobile manipulator using Jacobian-pseudoinverse-based control of the end-effector's motion (Chapter 13, Wheeled Mobile Robots)
Modern Robotics is now available as a MOOC (massive open online course) Specialization on Coursera!
This is a link to the Specialization home page. The Specialization consists of six short courses, each expected to take approximately four weeks of approximately five hours of effort per week:
- Course 1: Foundations of Robot Motion (Chapters 2 and 3)
- Course 2: Robot Kinematics (Chapters 4, 5, 6, and 7)
- Course 3: Robot Dynamics (Chapters 8 and 9)
- Course 4: Robot Motion Planning and Control (Chapters 10 and 11)
- Course 5: Robot Manipulation and Wheeled Mobile Robots (Chapters 12 and 13)
- Course 6: Capstone Project, Mobile Manipulation
- UR5 parameters you can use for dynamic simulations (note: the values are not exact, and do not account for the effect of gearing at the joints)
- The UR5 URDF file from Chapter 4 of the book (.pdf format or .txt format). For learning purposes only, not actual use; it contains only kinematic and inertial properties, and does not fully account for the effects of gearing. This file is based on the UR5 URDF from the ROS-Industrial team.
