Estimating anatomical wrist joint motion with a robotic exoskeleton.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robotic exoskeletons can provide the high intensity, long duration targeted therapeutic interventions required for regaining motor function lost as a result of neurological injury. Quantitative measurements by exoskeletons have been proposed as measu...

Simultaneous estimation of human and exoskeleton motion: A simplified protocol.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Adequate benchmarking procedures in the area of wearable robots is gaining importance in order to compare different devices on a quantitative basis, improve them and support the standardization and regulation procedures. Performance assessment usuall...

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...

Stiffness control of a nylon twisted coiled actuator for use in mechatronic rehabilitation devices.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Mechatronic rehabilitation devices, especially wearables, have been researched extensively and proven to be promising additions to physical therapy, but most designs utilize traditional actuators providing unnatural, robot-like movements. Therefore, ...

Applying a soft-robotic glove as assistive device and training tool with games to support hand function after stroke: Preliminary results on feasibility and potential clinical impact.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Recent technological developments regarding wearable soft-robotic devices extend beyond the current application of rehabilitation robotics and enable unobtrusive support of the arms and hands during daily activities. In this light, the HandinMind (Hi...

Bio-inspired control of joint torque and knee stiffness in a robotic lower limb exoskeleton using a central pattern generator.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robotic lower limb exoskeletons are becoming increasingly popular in therapy and recreational use. However, most exoskeletons are still rather limited in their locomotion speed and the activities of daily live they can perform. Furthermore, they typi...

Quantitative measures with WREX usage.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
This paper presents the results of two surveys conducted with users of a functional upper extremity orthosis called the Wilmington Robotic EXoskeleton (WREX). The WREX is a passive anti-gravity arm orthosis that allows people with neuromuscular disab...

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...

Self-aligning exoskeleton hip joint: Kinematic design with five revolute, three prismatic and one ball joint.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Kinematic compatibility is of paramount importance in wearable robotic and exoskeleton design. Misalignments between exoskeletons and anatomical joints of the human body result in interaction forces which make wearing the exoskeleton uncomfortable an...
