Design and analysis of a totally decoupled 3-DOF spherical parallel manipulator - ERRATUM

摘要

The following corrections to the paper by Zhang et al.1 should be noted. The corrected paper follows this notice. The title of the originally published paper should be corrected to "Design and analysis of a 3-DOF spherical parallel manipulator." In the whole text from Summary to Section 6 Kinetostatic Analysis, all instances of the word "decoupled" should be removed. Accordingly, some phrases and sentences should be revised as listed below. In Summary, the second sentence and the last two sentences should be deleted. In the Introduction section, the whole fourth paragraph should be deleted. In the last paragraph of Introduction, the first line, "fully decoupled" should be deleted. The second sentence should be deleted. The last sentence of this section should be changed into "Overall, this mechanism has a simple structure and is easy to control."
