This approach is based on relocating the center of rotation (COR) of the robotic walker and it si implemented online in training. This study aims to aid users that have difficulties in controlling their walking support system. To adapt user's controlling characteristics, a user is to follow some training path and the error between the training and actual path is used to change the COR of the system. This training process is done until the user can successfully follow the training path. Several training paths are considered and the relationship between user's intention in the form of applied force/torque and the new COR is taken. This relationship is used in the actual control implementation of a variable COR. Experimentation and evaluation are presented to show the validity of the proposed approach.","PeriodicalId":131431,"journal":{"name":"9th International Conference on Rehabilitation Robotics, 2005.

Design considerations characterizing the needs of this pediatric device are summarized. System components including the actuators, sensors and controllers are presented and evaluated. A proposed boot design that is currently under construction is presented and implementation issues are discussed.

Several research groups are attempting to automate this principle with robotic movement training devices. This paper derives an \"assist as needed\" robotic training algorithm by framing the problem as an optimization problem. We assume that motor recovery can be modeled as a process of learning a novel sensory motor transformation. The optimized robotic movement trainer is then an error-based controller with a forgetting factor. It bounds kinematic errors while systematically reducing its assistance. The same controller also works well if the dominant dynamics of recovery are akin to a strengthening process. We experimentally validate the controller with an unimpaired subject by demonstrating how the controller can help the subject to learn a novel sensory motor transformation (i.e. an internal model) with smaller kinematic errors than typical. The task studied here is walking on a treadmill in the presence of a novel dynamic environment. The assist-as-needed controller proposed here may be useful for limiting error during the learning of tasks in which large errors are dangerous or discouraging.","PeriodicalId":131431,"journal":{"name":"9th International Conference on Rehabilitation Robotics, 2005.

The human arm model is integrated within the control framework where the ANN uses estimated human arm parameters to select the appropriate PI gains.

Comparative experimental trials were conducted with 10 able-bodied subjects, with both the foot interface and an electromyographic (EMG)-based control. The results confirmed the effectiveness of the foot interface in the control of the hand prosthesis and showed a significant decrease in required adaptation and learning from the user's side.","PeriodicalId":131431,"journal":{"name":"9th International Conference on Rehabilitation Robotics, 2005.

To improve the current performance of below-knee prostheses, we study the feasibility of using the amputee's residual limb EMG signals to control the ankle position of an active ankle-foot prosthesis. We propose two control schemes to predict the amputee's intended ankle position: a neural network approach and a muscle model approach. We test these approaches using EMG data measured from an amputee for several target ankle movement patterns. We find that both controllers demonstrate the ability to predict desired ankle movement patterns qualitatively. In the current implementation, the biomimetic EMG-controller demonstrates a smoother and more natural movement pattern than that demonstrated by the neural network approach, suggesting that a biologically-motivated, model-based approach may offer certain advantages in the control of active ankle prostheses.","PeriodicalId":131431,"journal":{"name":"9th International Conference on Rehabilitation Robotics, 2005.

In addition, the effect of including autoregressive (AR) parameters into the input sets is examined. The average accuracies from four subjects are reported. It was observed that surface recordings based solely on amplitude data did not perform well (21.1% error) but adding AR coefficients increased this accuracy substantially (10.3%). The intramuscular recordings performed comparably to the surface recordings with AR coefficients using all ten (13.2%) and a smaller set of six (12.1%) channels of intramuscular data. The subset of six channels was selected using multinomial logistic regression. It was observed that adding the AR coefficients to the intramuscular recordings also produced an improvement in classification accuracy for the six (92.8%) and ten (93.7%) channel input sets. To our knowledge this is the first work in more than three decades that explores the use of intramuscular EMG for the control of upper-limb prostheses and this work demonstrates that it is possible to achieve a decrease in classification error of nearly 40% by using intramuscular recordings.","PeriodicalId":131431,"journal":{"name":"9th International Conference on Rehabilitation Robotics, 2005.

The personalization of the HMI, according to each end user, is crucial for the usability of any assistive technology. The control of complex devices, such as robot having many degrees of freedom (DOF), with a limited number of DOF at the level of the user, implies an appropriate design of the HMI to facilitate the interaction. Our research activities focus mainly at this level, which means not only providing several functionalities of the controlled system, but also on the presentation of those functionalities to the user. The challenge is to hide the complexity of any controlled system to the user, and particularly, when these users are having severe disabilities. Preliminary results are also presented. This work is funded by a European program, through the AMOR project, and by national support, through the Smart Home project. A demonstration of the running prototype is presented during the conference.","PeriodicalId":131431,"journal":{"name":"9th International Conference on Rehabilitation Robotics, 2005.
