MoBio: A 5 DOF trans-humeral robotic prosthesis.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
In this paper, a 5 DOF trans-humeral robotic prosthesis: MoBio is proposed. MoBio includes 2 DOF at wrist which is rare in other trans-humeral prostheses. Through anthropometric features MoBio prosthetic arm can achieve elbow flexion/extension, forea...

Design of a wearable interface for lightweight robotic arm for people with mobility impairments.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Many common activities of daily living like open a door or fill a glass of water, which most of us take for granted, could be an insuperable problem for people who have limited mobility or impairments. For years the unique alternative to overcame thi...

Design of a power-asymmetric actuator for a transtibial prosthesis.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
This paper presents the design and characterization of a power-asymmetric actuator for a transtibial prosthesis. The device is designed to provide the combination of: 1) joint locking, 2) high power dissipation, and 3) low power generation. This actu...

Automated assessment of symptom severity changes during deep brain stimulation (DBS) therapy for Parkinson's disease.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Deep brain stimulation (DBS) is currently being used as a treatment for symptoms of Parkinson's disease (PD). Tracking symptom severity progression and deciding the optimal stimulation parameters for people with PD is extremely difficult. This study ...

Learning from demonstration: Teaching a myoelectric prosthesis with an intact limb via reinforcement learning.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Prosthetic arms should restore and extend the capabilities of someone with an amputation. They should move naturally and be able to perform elegant, coordinated movements that approximate those of a biological arm. Despite these objectives, the contr...

Representing high-dimensional data to intelligent prostheses and other wearable assistive robots: A first comparison of tile coding and selective Kanerva coding.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Prosthetic devices have advanced in their capabilities and in the number and type of sensors included in their design. As the space of sensorimotor data available to a conventional or machine learning prosthetic control system increases in dimensiona...

Piecewise and unified phase variables in the control of a powered prosthetic leg.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Many control methods have been proposed for powered prosthetic legs, ranging from finite state machines that switch between discrete phases of gait to unified controllers that have a continuous sense of phase. In particular, recent work has shown tha...

Adaptive control of an exoskeleton robot with uncertainties on kinematics and dynamics.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
In this paper, we propose a new adaptive control technique based on nonlinear sliding mode control (JSTDE) taking into account kinematics and dynamics uncertainties. This approach is applied to an exoskeleton robot with uncertain kinematics and dynam...

Preliminary results toward a naturally controlled multi-synergistic prosthetic hand.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robotic hands embedding human motor control principles in their mechanical design are getting increasing interest thanks to their simplicity and robustness, combined with good performance. Another key aspect of these hands is that humans can use them...

Repeatability of grasp recognition for robotic hand prosthesis control based on sEMG data.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Control methods based on sEMG obtained promising results for hand prosthetics. Control system robustness is still often inadequate and does not allow the amputees to perform a large number of movements useful for everyday life. Only few studies analy...
