Analysis and experimental evaluation of a Stewart platform-based force/torque sensor [PDF]

The kinematic analysis and experimentation of a force/torque sensor whose design is based on the mechanism of the Stewart Platform are discussed. Besides being used for measurement of forces/torques, the sensor also serves as a compliant platform which ...

Learning-Based Estimation of Forward Kinematics for an Orthotic Parallel Robotic Mechanism

2025 International Conference On Rehabilitation Robotics (ICORR)
This paper introduces a 3D parallel robot with three identical five-degree-of-freedom chains connected to a circular brace end-effector, aimed to serve as an assistive device for patients with cervical spondylosis. The inverse kinematics of the system is solved analytically, whereas learning-based methods are deployed to solve the forward kinematics ...

3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications

Advanced Robotics Research, EarlyView.
Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.

4-RUPaR Parallel Robot Mechanisms and Their Kinematics Analysis

Journal of Mechanical Engineering, 2010
A novel 4-DOF spatial and symmetrical 4-RUPaR parallel robot mechanism that can perform three-dimensional translations and rotation about z axis (3T1R) is presented. The principles that the mechanism can perform the above motions are analyzed by using screw theory, the degree of freedom of the mechanism is calculated, and the rationality of chosen ...

Multiphoton‐Printed Microrobotic Arrays Powered by Discrete, Monolithically Integrated Hydrogel Actuators

Advanced Robotics Research, EarlyView.
Functional surfaces are investigated as a foundation for reconfigurable microscale systems with sensing and actuation capabilities. Advances in additive manufacturing enable our development of planar arrays of hybrid‐material, compliant microdevices that convert environmental stimuli into programmed motion and visual responses.
