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...

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...

Preliminary study of a robotic foot-ankle prosthesis with active alignment.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robotic prosthetic foot-ankle prostheses typically aim to replace the lost joint with revolute joints aimed at replicating normal joint biomechanics. In this paper, a previously developed robotic ankle prosthesis with active alignment is evaluated. I...

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...

Megane Pro: Myo-electricity, visual and gaze tracking data acquisitions to improve hand prosthetics.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
During the past 60 years scientific research proposed many techniques to control robotic hand prostheses with surface electromyography (sEMG). Few of them have been implemented in commercial systems also due to limited robustness that may be improved...

A lightweight robotic ankle prosthesis with non-backdrivable cam-based transmission.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Below-knee level amputation significantly impacts the ability of an individual to ambulate. Transtibial amputees are typically prescribed energetically passive ankle-foot prostheses that behave as a spring or controlled damper, and therefore cannot f...

Adaptive learning to speed-up control of prosthetic hands: A few things everybody should know.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Domain adaptation methods have been proposed to reduce the training efforts needed to control an upper-limb prosthesis by adapting well performing models from previous subjects to the new subject. These studies generally reported impressive reduction...

Novel neural interface electrode array for the peripheral nerve.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Peripheral neural interface (PNI) is becoming an essential technology in the field of robotic prosthesis due to its potential for providing bidirectional neural signal communication between the prosthetic arm and the brain. However, current PNIs inef...

User intent prediction with a scaled conjugate gradient trained artificial neural network for lower limb amputees using a powered prosthesis.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
Powered lower limb prostheses have the ability to provide greater mobility for amputee patients. Such prostheses often have pre-programmed modes which can allow activities such as climbing stairs and descending ramps, something which many amputees st...
