The use of robots to assist therapy of neurological motor disfunctions, such as limited mobility, is an emerging research field.
This book provides the first systematic application of a haptic control framework and assist as needed training paradigms to so called end-effector based gait simulation interfaces with a natural walking workspace, which fully carry the operator's bodyweight.
The developed haptic control framework provides a unified controller architecture and a design method based on robust adaptive control. Thus it allows for the stable interaction with virtual training environments. The modular virtual environments combine a walking scenario with an adjustable assistance along the desired training motion.
The framework is the basis to develop and implement compliant and patient-adaptive training strategies and, more generally speaking, haptic interaction on end-effector based gait interfaces.
The prototype was successfully implemented and tested on the walking simulator HapticWalker.
