Modern Robotics

The Cambridge University Press cover.

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. This page is under construction.

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

Book

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 date of the compilation of the book is noted on the front page.

The current, and final preprint, version of the book is dated November 2016. We posted a "beta" version of the book in early October 2016; that version should no longer be used. Since the October version we have implemented a number of corrections, clarifications, minor restructuring, and expanded coverage of certain topics. We also gratefully acknowledge the forewords provided by Roger Brockett and Matt Mason.

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 after latex'ing in Adobe Acrobat. 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, is 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.

Software

Download the book software from GitHub.

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. In September 2016, Northwestern MS student Mikhail Todes produced the first version of the software for distribution. The software will be updated as bugs are discovered and fixed. As of October 2016, the software distribution should be considered a beta version. A major revision will be coming in January 2017.

To report any issues with the software, please click the "Issues" tab in GitHub.

Simulation

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 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)

Videos

Welcome to Modern Robotics! (2:00)

Sometime early in 2017, more videos supporting the book will be posted to YouTube and linked to from this wiki. The videos will be made with Northwestern's Lightboard. If you are interested to learn more about what these videos might look like, you can check out the mechatronics videos at http://nu32.org.

You can see an excellent collection of robotics videos at the Springer Handbook of Robotics Multimedia Extension.

Supplemental Information

• 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.
• Open-source software for time-optimal time scaling (Chapter 9.4), courtesy of Quang-Cuong Pham.
