A Trade-Off between Complexity and Interaction Quality for Upper Limb Exoskeleton Interfaces

Exoskeletons are among the most promising devices dedicated to assisting human movement during reeducation protocols and preventing musculoskeletal disorders at work. However, their potential is currently limited, partially because of a fundamental…

Reoptimization of single-joint motor patterns to non-Earth gravity torques induced by a robotic exoskeleton

Gravity is a ubiquitous component of our environment that we have learned to optimally integrate in movement control. Yet, altered gravity conditions arise in numerous applications from space exploration to rehabilitation, thereby pressing the…

Physical Model of a Weld Bead Deposit on an Inclined or Horizontal Support Applied for Wire and Arc Additive Manufacturing

The present work is carried out in the framework of the WAS project [1] which deals with the WAAM process. The process relies on an automatized welding process in which a part is built by a successively deposed metal bead. Under a two-dimensional…

Convergence and robustness of the Hopf oscillator applied to an ABLE exoskeleton: reachability analysis and experimentation

In this paper, we consider an industrial exoskeleton called ABLE, which we controlled using an adaptive oscillator. In the context of periodic human movements around the elbow axis we show that the exoskeleton anticipates smoothly the human movement…

The value of time in the invigoration of human movements when interacting with a robotic exoskeleton

Time and effort are thought to be subjectively balanced during the planning of goal-directed actions, thereby setting the vigor of volitional movements. Theoretical models predicted that the value of time should then amount to high levels of effort…

Inferring Moore Machine for Adaptive Online Hybrid Automaton Identification

In the context of CPS modeling, this paper proposes a new method for online adaptive identification of hybrid systems. The method relies on a Moore machine identification process; We propose a mapping between a hybrid automaton and a discrete event…
