An Assistive Control Strategy for Rehabilitation Robots Using Velocity Field and Force Field.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
In this paper, we address the problem of assist-as-needed (AAN) control of rehabilitation robots. The objective is to develop a path tracking control scheme with the minimized intervention of the robot to gain active participation of impaired subject...

Virtual Reality Environments and Haptic Strategies to Enhance Implicit Learning and Motivation in Robot-Assisted Training.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Motivation plays a crucial role in motor learning and neurorehabilitation. Participants' motivation could decline to a point where they may stop training when facing a very difficult task. Conversely, participants may perform well and consider the tr...

Co-Ex: A Torque-Controllable Lower Body Exoskeleton for Dependable Human-Robot Co-existence.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
In this paper, we present our research study concerning the design and development of an exoskeleton that aims to provide 3D walking support with minimum number of actuators. Following a prior simulation study, the joint configuration was primarily d...

3-D Dynamic Walking Trajectory Generation for a Bipedal Exoskeleton with Underactuated Legs: A Proof of Concept.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
This paper presents a framework to address three dimensional (3-D) dynamic walking for a bipedal exoskeleton with underactuated legs. To achieve this goal, the framework is constructed via a trajectory generator and an optimized inverse kinematics al...

Development of a "transparent operation mode" for a lower-limb exoskeleton designed for children with cerebral palsy.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robot-assisted rehabilitation in children and young adults with Cerebral Palsy (CP) is expected to lead to neuroplasticity and reduce the burden of motor impairments. For a lower-limb exoskeleton to perform well in this context, it is essential that ...

Simulation on the Effect of Gait Variability, Delays, and Inertia with Respect to Wearer Energy Savings with Exoskeleton Assistance.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Exoskeletons are human-robot interfaces that have enormous potential to assist people with everyday tasks. To improve the design of exoskeletons for use in clinical populations, it is important to further our understanding of how exoskeleton design a...

Bio-inspired design and validation of the Efficient Lockable Spring Ankle (ELSA) prosthesis.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Over the last decade, active lower-limb prostheses demonstrated their ability to restore a physiological gait for transfemoral amputees by supplying the required positive energy balance during daily life locomotion activities. However, the added-valu...

A Model-Based Method for Minimizing Reflected Motor Inertia in Off-board Actuation Systems: Applications in Exoskeleton Design.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
The research and development of wearable robotic devices has been accelerated by off-board control and actuation systems. While off-board robotic actuation systems provide many benefits, the impedance at the robotic joint is often high. High joint im...

Gravity Compensation of an Exoskeleton Joint Using Constant-Force Springs.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Stroke is one of the leading causes of impairment in the world. Many of those who have suffered a stroke experience long-term loss of upper-limb function as a result. BLUE SABINO is an exoskeleton device being developed at the University of Idaho to ...

Multidimensional Capacitive Sensing for Robot-Assisted Dressing and Bathing.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robotic assistance presents an opportunity to benefit the lives of many people with physical disabilities, yet accurately sensing the human body and tracking human motion remain difficult for robots. We present a multidimensional capacitive sensing t...
