Smart Textiles that Teach: Fabric‐Based Haptic Device Improves the Rate of Motor Learning

Dario Floreano, Amy Roning Wu, Vivek Ramachandran, Fabian Maximilian Schilling

People learn motor activities best when they are conscious of their errors and make a concerted effort to correct them. While haptic interfaces can facilitate motor training, existing interfaces are often bulky and do not always ensure post-training skill ...

Symbitron Exoskeleton: Design, Control, and Evaluation of a Modular Exoskeleton for Incomplete and Complete Spinal Cord Injured Individuals

Auke Ijspeert, Florin Dzeladini, Amy Roning Wu

In this paper, we present the design, control, and preliminary evaluation of the Symbitron exoskeleton, a lower limb modular exoskeleton developed for people with a spinal cord injury. The mechanical and electrical configuration and the controller can be p ...

Mechanics of very slow human walking

Auke Ijspeert, Cole Stewart Simpson, Amy Roning Wu

Human walking speeds can be influenced by multiple factors, from energetic considerations to the time to reach a destination. Neurological deficits or lower-limb injuries can lead to slower walking speeds, and the recovery of able-bodied gait speed and beh ...

Haptic feedback perception and learning with cable-driven guidance in exosuit teleoperation of a simulated drone

Dario Floreano, Auke Ijspeert, Carine Rognon, Amy Roning Wu, Vivek Ramachandran

Robotics teleoperation enables human operators to control the movements of distally located robots. The development of new wearable interfaces as alternatives to hand-held controllers has created new modalities of control, which are more intuitive to use. ...

A simple model of mechanical effects to estimate metabolic cost of human walking

Auke Ijspeert, Salman Faraji, Amy Roning Wu

Since the advent of energy measurement devices, gait experiments have shown that energetic economy has a large influence on human walking behavior. However, few cost models have attempted to capture the major energy components under comprehensive walking c ...

Haptic Guidance with a Soft Exoskeleton Reduces Error in Drone Teleoperation

Dario Floreano, Auke Ijspeert, Carine Rognon, Stefano Mintchev, Amy Roning Wu

Haptic guidance has been shown to improve performance in many fields as it can give additional information without overloading other sensory channels such as vision or audition. Our group is investigating new intuitive ways to interact with robots, and we ...

Combining a 3D Reflex Based Neuromuscular Model with a State Estimator Based on Central Pattern Generators

Auke Ijspeert, Florin Dzeladini, Amy Roning Wu, Tycho Jan Henricus Brug

A neuromuscular model (NMC) presented by H. Geyer and extended by S. Song shows very interesting similarities with real human locomotion. The model uses a combination of reflex loops to generate stable locomotion and is able to cope with external disturban ...

A Versatile Neuromuscular Exoskeleton Controller for Gait Assistance: A Preliminary Study on Spinal Cord Injury Patients

Auke Ijspeert, Florin Dzeladini, Amy Roning Wu, Tycho Jan Henricus Brug

We investigated the capabilities of a reflex-based neuromuscular controller with a knee and hip gait trainer worn by a subject with a complete spinal cord injury. With controller assistance, this subject was able to reach a walking speed of 1.0m/s. Measure ...

An Adaptive Neuromuscular Controller for Assistive Lower-Limb Exoskeletons: A Preliminary Study on Subjects with Spinal Cord Injury

Auke Ijspeert, Florin Dzeladini, Amy Roning Wu, Tycho Jan Henricus Brug

Versatility is important for a wearable exoskeleton controller to be responsive to both the user and the environment. These characteristics are especially important for subjects with spinal cord injury (SCI), where active recruitment of their own neuromusc ...

Effects of a neuromuscular controller on a powered ankle exoskeleton during human walking

Auke Ijspeert, Florin Dzeladini, Etienne Burdet, Arash Arami, Daniel Renjewski, Amy Roning Wu

Wearable devices to assist abnormal gaits require controllers that interact with the user in an intuitive and unobtrusive manner. To design such a controller, we investigated a bio-inspired walking controller for orthoses and prostheses. We present (i) a S ...
