The robotics research program at Florida International University develops a broad range of robotic systems with a level of capability and robustness that supports long term, applied field operations. This paper provides insight into the design of a 1-Degree of Freedom (DOF) force-reflecting manual controller (FRMC) for the development of a teleoperation system by reviewing the wave variables t...

In this study, Fuzzy PID Control scheme is designed for an active suspension system. The main goal of an active suspension system for using in a vehicle model is reducing body deflections and handling high comfort for a passenger car. The present system was modelled as a two-degree-of-freedom (2-DOF) nonlinear vehicle model. Keywords—Active suspension system, Fuzzy PID controller, a nonlinear q...

Passive sensing of human hand and limb motion is important for a wide range of applications from human-computer interaction to athletic performance measurement. High degree of freedom articulated mechanisms like the human hand are di cult to track because of their large state space and complex image appearance. This article describes a model-based hand tracking system, called DigitEyes, that ca...

In this paper a model is proposed to evaluate individually the normalized fatigue at the joint level. More specifically our model distinguishes the two antagonist muscle groups acting for each degree of freedom (in short dof). The fatigue model parameters are normalized torques, joint strength and the maximum holding time that a posture can be maintained. Fatigue evolution is predicted taking i...

Abstract Variable Stiffness Actuator (VSA) is the core mechanism to achieve physical human–robot interaction, which an inevitable development trend in robotic. The existing variable stiffness actuators are basically single degree-of-freedom (DOF) rotating joints, achieving multi-DOF motion by cascades and resulting complex robot body structures. In this paper, integrated 2-DOF actuator with pro...

Magnetic miniature robots (MMRs) are small-scale, untethered actuators which can be controlled by magnetic fields. As these non-invasively access highly confined and enclosed spaces; they have great potential to revolutionize numerous applications in robotics, materials science, biomedicine. While the creation of MMRs with six-degrees-of-freedom (six-DOF) represents a major advancement for this...

The paper covers state of the art and latest development of piezoelectric motors at Kaunas University of Technology (Lithuania), that are related to the R&D of laser scanning and deflecting devices, measuring systems, nano-resolution positioning devices on the plane, various applications including teaching aids for Mechatronics studies and even “intelligent” toys. All presented motors are oneor...

The paper presented the trajectory performance of Modal Space Decoupled Controller (MSDC) and conventional joint space controller. Phase retarding amplitude fading were chosen to evaluate how well modal decoupling controller can follow a trajectory. responses sinusoidal inputs along six directions surge, sway, heave, roll, pitch, yaw given. result indicates that has better tracking when compare...
