TL;DR: A new adaptive multiple neural network controller with a supervisory controller for a class of uncertain nonlinear dynamic systems was developed in this paper and results on a cartpole system for the changing mass of the pole were illustrated to show the effectiveness of the proposed control scheme.

TL;DR: Estimation of walking behavior such as gait pattern, speed and distance of walking, is discussed in this paper and it can be applied as a virtual controller to human-machine interfaced system.

TL;DR: An intelligent walking-assistance robot system has been developed to help the elderly or the disabled in rehabilitation programs and tested on patients in hospital and the experimental results are reported.

TL;DR: The neural network based control algorithm for a mobile manipulator used to compensate for dynamic interactions, unmodeled dynamics, and disturbances by the user on the system, is derived and experimental results are shown.

TL;DR: A neural network based controller is derived for a mobile manipulator to track the given trajectories in the workspace by the radial basis function network with weight adaptation rule derived from the Lyapunov function.
