Modeling of Linear Displacement and Design of Adaptive Robust Controller
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 Twisted‐string actuation method has attracted much more attention due to its compact size and considerable output force. Many studies have been proposed to estimate its linear displacement of actuation based on the angular measurement of the rotary device.

Design and Performance Analysis of a TLET‐Type Flexure Hinge
Advances in Materials Science and Engineering, Volume 2020, Issue 1, 2020., 2020 In order to permit a large deflection, three lamina emergent torsional flexure hinges are reconfigured to create a new triple LET‐type flexure hinge (TLET) in this paper. The TLET consists of flexure hinges in a series coupled with others in parallel configuration. This arrangement is aimed to enhance the displacement of the joint.

On the kinetostatic optimization of revolute-coupled planar manipulators [PDF]
Mechanism and Machine Theory, 2002 Proposed in this paper is a kinetostatic performance index for the optimum dimensioning of planar manipulators of the serial type. The index is based on the concept of distance of the underlying Jacobian matrix to a given isotropic matrix that is used as a reference model for purposes of performance evaluation.

Interaction Control for Human‐Exoskeletons
Journal of Control Science and Engineering, Volume 2020, Issue 1, 2020., 2020 In this work, a general concept of the human‐exoskeleton compatibility and interaction control is addressed. Rehabilitation, as applied to humans with motor control disorder, involves repetitive gait training in relation to lower limb extremity and repetitive task training in relation to upper limb extremity.

Kinetostatic Optimization for Kinematic Redundancy Planning of Nimbl’Bot Robot
Journal of Mechanisms and Robotics, 2023 AbstractIn manufacturing industry, computer numerical control (CNC) machines are often preferred over industrial serial robots (ISR) for machining tasks. Indeed, CNC machines offer high positioning accuracy, which leads to slight dimensional deviation on the final product.

Design Optimization of a Cable-Driven Two-DOF Flexible Joint Module
International Journal of Advanced Robotic Systems, 2012 This paper focuses on the kinematics, kinetostatics and design optimization of a 2-DOF cable-driven flexible joint module. Based on the motion characteristics of the 2-DOF joint module, the concept of instantaneous screw axis in conjunction with the ...

An Active Knee–Ankle–Foot Orthosis With Torque‐Dense, Low‐Impedance Knee Actuation
Advanced Intelligent Systems, EarlyView.This article presents the simulation, design, and clinical validation of a robotic active KAFO with torque‐sensitive actuation. By passively and continuously adapting the transmission ratio in response to the knee torque, the torque‐sensitive actuator overcomes the tradeoff between torque, weight, and impedance observed in conventional robot actuators,
