Errata below are for the hardcover book published by Cambridge University Press and the preprint version of the book posted on May 3, 2017. Thanks to everyone who provided corrections to earlier versions!
- In the displayed equation just after Equation (3.76), the left-hand side should be (the brackets are missing).
- Equation (5.7): The the first two terms on the right-hand side of the equation should be .
- Exercise 5.16 and Figure 5.26: The robot is referred to as PRRRRR, but it is PRPRRR.
- Chapter 6.3, first line after Eq (6.7): the matrices and are referred to as twists, but these are the se(3) matrix representations of the twists.
- Figure 8.5 says the volume of the rectangular parallelepiped is abc but it should be hlw.
- Exercise 8.6(a): The expression has the indices switched; the correct expression is .
- Exercise 8.7: The expression should be written:
- Equation (10.4) should read (the plus sign in the book should be a minus sign).
- In the displayed equation after Equation (11.18), the vector Xe(t) is a six-vector. The bottom three elements are written correctly, but the top three elements, an angular velocity, are written instead in their 3x3 so(3) form.
- Figure 11.24, the Robonaut 2 series elastic actuator, 4th sentence of the caption: The words "outer" and "inner" should be switched, so the new sentence reads "The inner ring of hole mounts connects to the harmonic gearhead output, and the outer ring of hole mounts is the output of the SEA, connecting to the next link."
Minor typos, etc., no danger of misunderstanding
- (online version only) Description of Chapter 6: "jont positions" should be "joint positions."
- Chapter 2.2.2, Example 2.3: "Substituting" is misspelled.
- (online version only) Figure 6.7: θ0 should be θ0 (five times) and θ1 should be θ1 (one time).
- Just below caption for Figure 7.8: There is an extraneous dot.
- (online version only) Chapter 8.1.1, last paragraph: is improperly typeset.
- Caption of Figure 12.14, second-to-last sentence: "rotation if possible" should be "rotation is possible."
