Variable Stiffness Mechanism in Robotized Interventional Radiology

2016
During the last two decades, a large number of robotic assistants have been developed to help surgeons place surgical tools. Until now, research in this field has mostly focused on rigid robotic structures, which make safety issues difficult to deal with. In this paper, we consider a new collaborative manipulation approach based on a variable stiffness

A Magnetic Lead Screw with Variable Stiffness Mechanism

2019 12th International Symposium on Linear Drives for Industry Applications (LDIA), 2019
A magnetic lead screw (MLS) is a kind of feed screw that allows non-contact power transmission by a magnetic force. It can be driven efficiently due to no frictional contact, and flexibly respond to an external force by its magnetic spring characteristic.

Achieving High Stiffness Range of Force Feedback Gloves using Variable Stiffness Mechanism

2019 IEEE World Haptics Conference (WHC), 2019
Force feedback glove is a promising interface for producing immersive haptic sensation in virtual reality and teleoperation systems. One open problem of existing gloves is to simulate virtual objects with adjustable stiffness in a fast dynamic response, along with lightweight and good back-drivability.

Stiffness evaluation of a tendon-driven robot with variable joint stiffness mechanisms

2017 IEEE-RAS 17th International Conference on Humanoid Robotics (Humanoids), 2017
This paper proposes a new tendon-driven robot with variable joint stiffness mechanisms. The tendon-driven robot is able to vary the stiffness of joints by sliding variable stiffness mechanisms over the link by wire tensions. As a reason for that structure and moment arms of the tendon-driven robot are changed depending on the position of the variable ...

Analytical conditions for the design of variable stiffness mechanisms

2017 IEEE International Conference on Robotics and Automation (ICRA), 2017
This paper introduces an analytical approach for the design of variable stiffness mechanisms. The basis of this approach is a general model — representing the potential energy function and the physical constraints — covering the design space of variable stiffness mechanisms.

Single motor-variable stiffness actuator using bistable switching mechanisms for independent motion and stiffness control

2016 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2016
This paper presents a proof of concept of a variable stiffness actuator (VSA) that uses only one (high power) input motor. In general, VSAs use two (high power) motors to be able to control both the output position and the output stiffness, which possibly results in a heavy, and bulky system.
