Kinematics and Singularity Analysis of a Crrhhrrc Parallel Schönflies Motion Generator

A novel architecture for a parallel Schönflies motion generator was recently proposed, consisting of a CRRHHRRC linkage. The novelty of this architecture lies in its simplicity, as it comprises only two limbs, thereby forming a single-loop closed kinematic chain. Reported in this paper is a realization of this architecture, intended for the production of a proof-of-concept prototype. The realiz...

A Flexible, Parallel Generator of Natural Language

My Ph.D. thesis (Ward 1992, 1991)1 addressed the task of generating natural language utterances. It was motivated by two difficulties in scaling up existing generators. Current generators only accept input that are relatively poor in information, such as feature structures or lists of propositions; they are unable to deal with input rich in information, as one might expect from, for example, an...

Parallel 3d Mesh Generator

SUMMARY An innovative approach for parallel discretization of 3D domains is presented. The paralleliza-tion strategy is based on domain decomposition concept. Two levels of domain decomposition are considered | the model level and model entity parametric tree level. The decomposition on the model level splits the model into domains on the model entity basis. Since the decomposition may become u...

A joint trajectory generator for motion recovery

A joint trajectory generator for motion recovery" (2003). All Faculty Publications. Paper 509. SUMMARY This paper describes an adaptive S-curve used to recover a tool path upon a system crash in the Windows operating system (OS). For a mechanism such as a robot or machine tool, the joint values, being delivered as setpoints to the servo-controller, are dynamically recorded by the real-time oper...
