A Stiffness Estimator for Agonistic-Antagonistic Variable-Stiffness-Actuator Devices

Safe Physical Human Robot Interaction, conservation of energy and adaptability are just the main robotic applications that prompted the development of a number of Variable Stiffness Actuators (VSA). Implemented in a variety of ways, they use various technologies, and feature the most diverse mechanical solutions, all of which share a fundamentally unavoidable nonlinear behavior. The control sch...

Semi-active Control of Building Structures using Variable Stiffness Device and Fuzzy Logic

Semi-active control devices, also called “Intelligent” control devices, constitute the positive aspects of both the passive and active control devices. A semi-active control strategy is similar to the active control strategy, but this control device has been shown to be more energy-efficient than active devices. A particular type of semi-active control device, the Variable Stiffness Device (VSD...

AVASTT: A New Variable Stiffness Actuator with Torque Threshold

Variable Stiffness Actuators (VSAs) emerged as an alternative to conventional actuators in a variety of applications, such as walking robots and service robotics. New requirements, which were obviated in the design of rigid actuators, must be accounted for during the mechanical design of such new devices. Among them, we find the possibility of tunning the natural frequency of the mechanical sys...

Resonance-based Control Method for Multi-Joint Robot with Variable Joint Stiffness

This study presents resonance-based control methods proposed by the authors for multi-joint robots. The proposed control methods adjust stiffness of mechanical elements installed in each joint of the robots to minimize actuator torque while generating desired periodic motions. Some of these control method adjust not only stiffness but also motion patterns to reduce further actuator torque. Adva...

Analysis and Control of Variable Stiffness Robots

This dissertation addresses the analysis and control of variable stiffness actuated robots aiming at precise, sensitive, robust, and dynamic interaction with their environment and especially humans. The focus is the adjustment of impedance properties, namely adjusting the robot equilibrium position, the stiffness, and damping. Highest demands are met by the development of new control concepts a...
