摘要：
This paper introduces a parallel robot with schonflies motion. The robot can be used in packaging production lines to realize high-speed pick-and-place manipulation. It is composed of four identical limbs and a single platform. As a result, this robot has better dynamic response potential. Based on the inverse kinematics modelling, the singularity issue of this robot has been investigated. By taking the transmission performance into consideration, the input transmission singularity index and the output transmission singularity index have been defined on the basis of screw theory. Thereafter, the robot with specific geometric parameters has been taken as an example, and the corresponding singular loci have been derived. The kinematics modeling and singularity analysis presented in this paper is very helpful to the development of the robot.
