Hybrid force-motion control of coordinated robots interacting with unknown environments (2014)
Presentation / Conference Contribution

© 2014 Institute of Control, Robotics and Systems (ICROS). This paper presents a unified framework for system design and control in cooperative robotic systems. It introduces a highly general cooperative system configuration involving any number of m... Read More about Hybrid force-motion control of coordinated robots interacting with unknown environments.

Sliding mode hybrid impedance control of robot manipulators interacting with unknown environments using VSMRC method (2013)
Presentation / Conference Contribution

In the present paper, the objective of hybrid impedance control is specified and a robust hybrid impedance control approach is proposed. Based on the concept of hybrid control, the task space is decomposed into position and force controlled subspaces...

Multi degree-of-freedom input-to- state stable approach for stable haptic interaction
Presentation / Conference Contribution

Passivity has been the most often used constraint for the controller design of haptic interfaces. However, the designed controller based on passivity constraint has been suffering from its conservatism, especially when the user wants to increase the...

Independent force and position control for cooperating manipulators handling an unknown object interacting with an unknown environment
Presentation / Conference Contribution

In this paper, we consider two manipulators grasping a rigid object in contact with a deformable working surface, whose real physical parameters are unknown. Dynamics of the closed chain mechanism is expressed based on the objects center of mass, and...

Successive stiffness increment approach for high stiffness haptic interaction
Presentation / Conference Contribution

This paper proposes a method to further enlarge the displayed stiffness range of the impedance-type haptic interfaces. Numerous studies have been done for a stable haptic interaction in a wide impedance range. However, most of the approaches sacrific...

Input-to-State Stable Approach for Haptic Interface and Teleoperation Systems
Thesis

Passivity has been a major criterion on designing a stable haptic interface due to many advantages. However, passivity has been suffering from its intrinsic conservatism since it only represents a small set of the whole stable region. Therefore, ther...
