International Journal of Advanced Robotic Systems, 2014 This paper presents a comparison study of two important three-degree-of-freedom (DOF) parallel manipulators, the Sprint Z3 head and the A3 head, both commonly used in industry. As an initial step, the inverse kinematics are derived and an analysis of two

Transmission Angle Analysis of a Type of Parallel Manipulators
Applied Sciences, 2022 In most research works, the conditioning index is used to analyze the kinematic performance of a type of parallel manipulators whose traveling plate has only translation in the workspace, and each limb is made up of three joints and two moving links ...

Data-Parallel String-Manipulating Programs [PDF]
ACM SIGPLAN Notices, 2015 String-manipulating programs are an important class of programs with applications in malware detection, graphics, input sanitization for Web security, and large-scale HTML processing. This paper extends prior work on BEK, an expressive domain-specific language for writing string-manipulating programs, with algorithmic insights that make BEK both ...

On the determination of cusp points of 3-R\underline{P}R parallel manipulators [PDF]
, 2010 This paper investigates the cuspidal configurations of 3-RPR parallel manipulators that may appear on their singular surfaces in the joint space. Cusp points play an important role in the kinematic behavior of parallel manipulators since they make ...

Parallelism in manipulator dynamics [PDF]
Proceedings. 1985 IEEE International Conference on Robotics and Automation, 1985 This paper addresses the problem of efficiently computing the motor torques required to drive a manipulator arm in free motion, given the desired trajectory—that is the inverse dynamics problem. It analyzes the high degree of parallelism inherent in the computations and presents two "mathemati cally exact "formulations especially suited to high-speed,
