To study the characteristics of the parallel robot\u2019s spatial positions and poses, the inverse solutions of the moving platform\u2019s spatial positions and poses as well as the workspace where objects were ground were established by using DH parameters and geometric methods. The experimental results showed that the workspace where objects were ground was a cylinder with a cross section similar to a symmetric circular sector. To analyze the characteristics of the forces produced by the parallel robotic system, the dynamics equation was established via the Newton\u2013Euler method to verify the rationality of the force decoupling design. Theoretical calculation combined with simulation and experimental analyses confirmed the viability of the theoretical analyses which lay a theoretical foundation for the design, manufacture and control of the parallel robotic system proposed in this paper.<\/jats:p>","DOI":"10.3390\/sym14040825","type":"journal-article","created":{"date-parts":[[2022,4,20]],"date-time":"2022-04-20T00:22:43Z","timestamp":1650414163000},"page":"825","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":72,"title":["Analysis of Position, Pose and Force Decoupling Characteristics of a 4-UPS\/1-RPS Parallel Grinding Robot"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0208-2316","authenticated-orcid":false,"given":"Jun","family":"Wang","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Hubei University of Technology, Wuhan 430068, China"}]},{"given":"Fei","family":"Liang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Hubei University of Technology, Wuhan 430068, China"}]},{"given":"Hongjun","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Hubei University of Automotive Technology, Shiyan 442002, China"}]},{"given":"Mingquan","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Hubei University of Technology, Wuhan 430068, China"}]},{"given":"Quan","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Hubei University of Technology, Wuhan 430068, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"286","DOI":"10.1109\/TRO.2016.2516025","article-title":"Kinematically Redundant Spatial Parallel Mechanisms for Singularity Avoidance and Large Orientational Workspace","volume":"32","author":"Gosselin","year":"2016","journal-title":"IEEE Trans.
