Angle Attitude Control for a 2-DOF Parallel Mechanism of PMAs Using Tracking Differentiators
IEEE transactions on industrial electronics (1982. Print), 2019This paper presents a Tornambe controller (TC) for a two-degree-of-freedom (DOF) parallel mechanism of pneumatic muscle actuators (PMAs) based on tracking differentiators (TDs).

Constraint singularities of parallel mechanisms
Proceedings 2002 IEEE International Conference on Robotics and Automation (Cat. No.02CH37292), 2003The concept of constraint singularity is introduced. This is a phenomenon occurring in parallel mechanisms with reduced freedoms when the screw system, formed by the constraint wrenches in all legs, loses rank.

Redundancy resolution and control of a novel spatial parallel mechanism with kinematic redundancy
Mechanism and Machine Theory, 2019In this paper, a spatial kinematically redundant parallel mechanism consisting of three base prismatic actuators and six lateral prismatic actuators which control the six task space degrees of freedom is proposed.

Sensory redundant parallel mobile mechanism
Proceedings 2001 ICRA. IEEE International Conference on Robotics and Automation (Cat. No.01CH37164), 2002This paper presents a novel design for a mobile robot based on the kinematics of parallel mechanisms. The robot consists of 3 legs, each equipped with an asynchronous driving unit. The legs are connected to the driving units with spherical joints and to the upper plate with a revolute joint.

Kinematics and reliable analysis of decoupled parallel mechanism for ankle rehabilitation
Microelectronics and reliability, 2019The rehabilitation training is the key process for restoring the normal physiological functions for patients. The rehabilitation robot has been developed for the reason that it can help patient complete the repeated training process.

A Soft Parallel Kinematic Mechanism
Soft Robotics, 2018In this article, we describe a novel holonomic soft robotic structure based on a parallel kinematic mechanism. The design is based on the Stewart platform, which uses six sensors and actuators to achieve full six-degree-of-freedom motion. Our design is much less complex than a traditional platform, since it replaces the 12 spherical and universal ...

Stiffness analysis of a metamorphic parallel mechanism with three configurations
, 2019Compared with series mechanisms, a parallel mechanism has the merits of high stiffness, fast response, and centralised layout of electric cylinders, which is more suitable for the mechanical leg of a rescue robot.

Design and analysis of a multi-mode mobile robot based on a parallel mechanism with branch variation
Mechanism and Machine Theory, 2018In this paper we propose the design idea of branch variation of a mobile parallel mechanism so that it can execute different locomotion modes. A novel robot is presented based on this idea, which can be reconfigured to be different equivalent mobile ...
