Book
Differentially Flat Systems
TL;DR: This chapter discusses linear time-Invariant SISO Systems, MIMO Systems, and Flatness and Optimal Trajectories.
Journal ArticleDOI
Robot Assisted Gait Training With Active Leg Exoskeleton (ALEX)
TL;DR: In this paper, a robot assisted gait training (RAGT) was developed for stroke survivors using active leg exoskeleton (ALEX) and a force-field controller, which uses assist-as-needed paradigm for rehabilitation.
Journal ArticleDOI
Velocity and position control of a wheeled inverted pendulum by partial feedback linearization
TL;DR: The dynamic model of a wheeled inverted pendulum (e.g., Segway, Quasimoro, and Joe) is analyzed from a controllability and feedback linearizability point of view and two novel controllers are designed.
Journal ArticleDOI
Design of a Cable-Driven Arm Exoskeleton (CAREX) for Neural Rehabilitation
Ying Mao,Sunil K. Agrawal +1 more
TL;DR: This paper is the first to demonstrate via experiments with cable-driven arm exoskeleton (CAREX) that it is possible to achieve desired forces on the hand, i.e., both pull and push, in any direction as required in neural training.
Proceedings ArticleDOI
Active Leg Exoskeleton (ALEX) for Gait Rehabilitation of Motor-Impaired Patients
TL;DR: It was shown that a healthy subject could be retrained in about 45 minutes with ALEX to walk on a treadmill with a significantly altered gait, and this powered orthosis will be used for gait training of stroke patients in the coming months.
