Significant corrections

Chapter 5

• Equation (5.7): The second term on the right-hand side of the equation should be Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle J_{s2}(\theta) \dot{\theta}_2} .

Chapter 6

• Chapter 6.3, first line after Eq (6.7): the matrices $T_{sd}^{-1}{\dot {T}}_{sd}$ and Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \dot{T}_{sd} T_{sd}^{-1}} are referred to as twists, but these are the se(3) matrix representations of the twists.

Chapter 8

• Figure 8.5 says the volume of the rectangular parallelepiped is Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle abc} but it should be $hlw$.

Chapter 11

• In the displayed equation after Equation (11.18), the vector Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle X_e(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 $3\times 3$ $so(3)$ form.

Minor typos, etc., no danger of misunderstanding

Chapter 1

• (online version only) Description of Chapter 6: "jont positions" should be "joint positions."

Chapter 2

• Chapter 2.2.2, Example 2.3: "Substituting" is misspelled.

Chapter 6

• (online version only) Figure 6.7: Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \theta_0} should be $\theta ^{0}$ (five times) and $\theta _{1}$ should be Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \theta^1} (one time).

Chapter 7

• Just below caption for Figure 7.8: There is an extraneous dot.

Chapter 8

• (online version only) Chapter 8.1.1, last paragraph: ${\dot {\theta }}_{1}$ is improperly typeset.
