Experimental Analysis of Type II Singularities and Assembly Change Points in a 3UPS+RPU Parallel Robot
Jose L. Pulloquinga, Vicente Mata, Angel Valera +3
Parallel robots (PRs) have singular configurations where the robot gains at least one degree of freedom and loses control. Theoretically, such singularity occurs when the Forward J…
