Simplified Motor Primitives for Gait Symmetrization: Pilot Study with an Active Hip Orthosis

ICRA 2023poster

Lower-limb exoskeletons are wearable devices whose main purposes are human rehabilitation and bilateral locomotion assistance. In particular, there is a growing interest for their use to symmetrize the gait of hemiparetic patients. This often consists in using the kinematics of the less affected sid…

Experimental Assessment of a Control Strategy for Locomotion Assistance Relying on Simplified Motor Primitives

IROS 2022poster

Lower-limb exoskeletons are robotic devices that can provide assistance to human locomotion. Since they are expected to be used in ecological environments, their control strategy should handle different kinds of daily-life situations. Taking inspiration from the human neuromuscular system - and part…

Predicting the effects of oscillator-based assistance on stride-to-stride variability of Parkinsonian walkers

ICRA 2022poster

Parkinson's disease is a severe neurodegenerative disorder that affects sensorimotor control. In particular, several gait impairments are reported, including a decrease of long-range autocorrelations in stride duration time series. This complex statistics is potentially a biomarker of the risk of fa…

Online Learning of the Dynamical Internal Model of Transfemoral Prosthesis for Enhancing Compliance

RA-L 2021

Powered prostheses hold promises to restore adaptive and robust locomotion to lower-limb amputees. However, their daily use is still challenged by several shortcomings, on top of which those related to their control methods. This letter reports the development of an adaptive controller for a transfe

Autonomous view selection and gaze stabilization for humanoid robots

IROS 2017poster

To increase the autonomy of humanoid robots, the visual perception must support the efficient collection and interpretation of visual scene cues by providing task-dependent information. Active vision systems allow to extend the observable workspace by employing active gaze control, i.e. by shifting…

Biped gait controller for large speed variations, combining reflexes and a central pattern generator in a neuromuscular model

ICRA 2015poster

Controllers based on neuromuscular models hold the promise of energy-efficient and human-like walkers. However, most of them rely on optimizations or cumbersome hand-tuning to find controller parameters which, in turn, are usually working for a specific gait or forward speed only. Consequently, desi…

Experimental validation of a bio-inspired controller for dynamic walking with a humanoid robot

IROS 2015poster

Bipedal walking with humanoid robots requires efficient real-time control. Nowadays, most bipedal robots require to ensure local stability at every instant in time, preventing them from achieving the impressive human walking skills. At the same time, bio-inspired walking controllers are emerging, th…

Novel infinitely Variable Transmission allowing efficient transmission ratio variations at rest

IROS 2015poster

Recent studies showed that Continuously Variable Transmissions (CVT) and Infinitely Variable Transmissions (IVT) can considerably improve the locomotion efficiency in legged robot. A CVT is a transmission whose ratio can be continuously varied and an IVT is a transmission whose ratio can be continuo…
