Correction: Palacín et al. Evaluation of the Path-Tracking Accuracy of a Three-Wheeled Omnidirectional Mobile Robot Designed as a Personal Assistant. Sensors 2021, 21, 7216

After publication of the research paper [1], the authors wish to make the following corrections. In the original publication, there was a mistake in the typeset of Equations (31)–(33).

In Equation (31), the order of the product of the matrixes was not correct. The correct Equation (31) is:

$$\left[\begin{array}{c}{\omega }_a\\ {\omega }_b\\ {\omega }_c\end{array}\right]=\left[\begin{array}{ccc}{\displaystyle \frac{1}{r_a}}& 0& 0\\ 0& {\displaystyle \frac{1}{r_b}}& 0\\ 0& 0& {\displaystyle \frac{1}{r_c}}\end{array}\right]\left[\begin{array}{c}{V}_a\\ V_b\\ V_c\end{array}\right]$$

In Equation (32), there was a mistake in the conversion. The correct Equation (32) is:

$$\left[\begin{array}{c}{\omega }_{MA}\\ {\omega }_{MB}\\ {\omega }_{MC}\end{array}\right]=\left[\begin{array}{c}{\omega }_a\\ {\omega }_b\\ {\omega }_c\end{array}\right]·{\displaystyle \frac{60}{2\pi }}·{\displaystyle \frac{64}{1}}$$

(32)

In Equation (33), there was a mistake in the conversion. The correct Equation (33) is:

$$\left[\begin{array}{c}{\omega }_a\\ {\omega }_b\\ {\omega }_c\end{array}\right]=\left[\begin{array}{c}{\omega }_{MA}\\ {\omega }_{MB}\\ {\omega }_{MC}\end{array}\right]·{\displaystyle \frac{2\pi }{60}}·{\displaystyle \frac{1}{64}}$$
