Pattern generation and compliant feedback control for quadrupedal dynamic trot-walking locomotion: experiments on roboCat-1 and hyQ
(Springer Science+Business Media, 2015-04)
In this paper, we introduce a method that synergistically combines an analytical pattern generator and a feedback controller frame, which are developed for the purpose of synthesizing dynamic quadrupedal trot-walking ...
Proof of concept for robot-aided upper limb rehabilitation using disturbance observers
(IEEE, 2015-02)
This paper presents a wearable upper body exoskeleton system with a model-based compensation control framework to support robot-aided shoulder-elbow rehabilitation and power assistance tasks. To eliminate the need for EMG ...
Torque and variable stiffness control for antagonistically driven pneumatic muscle actuators via a stable force feedback controller
(IEEE, 2015)
This paper describes a novel controller that is capable of simultaneously controlling torque and variable stiffness in real-time, for actuators with antagonistically driven pneumatic artificial muscles (PAMs). To this end, ...
Towards balance recovery control for lower body exoskeleton robots with variable stiffness actuators: spring-loaded flywheel model
(IEEE, 2015)
This paper presents a biologically-inspired real-time balance recovery control strategy that is applied to a lower body exoskeleton with variable physical stiffness actuators at its ankle joints. For this purpose, a torsional ...
Environmental force estimation for a robotic hand : compliant contact detection
(IEEE, 2015)
This paper presents a model based compensation method to enable environmental force estimation for a robotic hand with no tactile or force sensors. To this end, we utilize multi-joint robot dynamics and disturbance observer ...
