Modern Robotics Errata

The errata below are for the updated first edition of Modern Robotics (as well as the practice exercises and linear algebra refresher appendix). The updated first edition (also called "version 2") was originally published by Cambridge University Press in late 2019 (marked "3rd printing 2019" or later) and the corresponding online preprint is dated December 2019. The updated first edition includes several corrections and minor additions to the original first edition, which was originally published by Cambridge in May 2017, with a corresponding online preprint dated May 2017.

The errata for the original first edition can be found here.

Book: Significant corrections

Chapter 3

• (printed version only) At the end of the introduction Exercise 3.16, it says "origin of {b} is at (0,2,0) is {s}" but "is {s}" should be "in {s}".
• Exercise 3.20, Figure 3.26: In the figure, the y and z axes for the {a}, {b}, and {c} frames are switched (y should point forward and z should point up). Also, the space frame is located at the bottom of the small wheel, directly below the {a} frame.
• (printed version only) Exercise 3.25(a): the element in the third row and third column of the matrix $A$ should be 0 (it is incorrectly written as 1).

Chapter 8

• (printed version only) Equation (8.74): the first two plus signs should be minus signs.

Book: Minor typos, etc., no danger of misunderstanding

Throughout the book

• The V-REP simulator has been discontinued and replaced by the CoppeliaSim simulator. This does not change anything in the book (or the simulation scenes provided to accompany the book).

Chapter 6

• (printed version only) Chapter 6.2.2, Example 6.1: just before the matrix $T_{sd}$, "corresponds to to" should be "corresponds to."
• (printed version only) Chapter 6.3, first sentence after Equation (6.7): "however small" should be written "however, small" to avoid ambiguity.

Chapter 11

• (online version only) Chapter 11.3.3: The sentence containing Equation (11.18) is missing a period at the end.
