Modeling and Optimization for a New Compliant 2-dof Stage for Locating Biomaterial Samples by an Efficient Approach of a Kinetostatic Analysis-Based Method and Neural Network Algorithm. [PDF]

open access: yesComput Intell Neurosci, 2022
The nanoindentation technique is employed to characterize the behaviors of biomaterials. Nevertheless, there is a lack of development of a miniaturized precise positioner for in situ nanoindentation. Besides, modeling behaviors of the positioner are restricted due to its complex kinematic characteristics.

TetraFLEX: Design and kinematic analysis of a novel self‐aligning family of 3T1R parallel manipulators

open access: yesJournal of Field Robotics, Volume 39, Issue 5, Page 617-630, August 2022., 2022
Abstract A new family of 3T1R parallel manipulators (PMs) with self‐aligning property, named TetraFLEX, is presented. 3T1R manipulators have many applications in different fields. Moreover, self‐aligning property refers to the presence of passive joints in the PM limbs that are conceived to compensate for possible misalignments between the sliding ...
