    • Design of a Multifunctional Flow Control Valve for Self-Circulating Hydraulic Cylinders 

      Moosavian, Amin; Rizoiu, Michael; (Jeff) Xi, Fengfeng (The American Society of Mechanical Engineers (ASME), 2017)
      A new hydraulic circuit is introduced, packaged as a singular component and referred to as a multifunctional flow control (MFC) valve, for usage in conjunction with self-circulating hydraulic cylinders. Unlike conventional ...

    • Dimensional Synthesis of a MultiLoop Linkage With Single Input Using Parameterized Curves 

      Moosavian, Amin; Zhu (John) Sun, Cong; (Jeff) Xi, Fengfeng; Inman, Daniel J. (The American Society of Mechanical Engineers (ASME), 2017)
      In this paper, a new design is presented for shape morphing using parameterized curves. Inspired by minimal actuation effort, a multiloop linkage is designed with a single input, allowing a morphing curve to take on three ...

    • Reconfiguration Analysis of a Fully Reconfigurable Parallel Robot 

      Daniel Finistauri, Allan; (Jeff) Xi, Fengfeng (The American Society of Mechanical Engineers (ASME), 2013)
      This paper presents a new method for the combined topological and geometric reconfiguration of a parallel robot to achieve taskbased reconfiguration. Using the existing structure of a six degreeoffreedom (DOF) parallel ...

    • Tip-Over Stability Analysis for a Wheeled Mobile Manipulator 

      Guo, Shuai; Song, Tao; (Jeff) Xi, Fengfeng; Mohamed, Richard Phillip (The American Society of Mechanical Engineers (ASME), 2017)
      A method is presented for tip-over stability analysis of a wheeled mobile manipulator. A wheeled mobile manipulator may tip over resulting from its operation. In this study, first a Newton–Euler formulation is applied to ...
