—A new adaptive controller based on multiple neural networks (NNs) for an uncertain robot manipulator system is developed in this paper. The proposed multiple neuro-adaptive controller (MNAC) switches to a memorized control skill or blends multiple skills by using visual information on the given job to improve the transient response at the time of task(More)
— A power assisted gait rehabilitation robot system by which a patient who has difficulty in walking can exercise is proposed. Our developed system consists of a robotic manipulator which can adjust the height of the system according to the user and a mobile base with two-driving wheels. It is similar to the architecture of a mobile manipulator. The neural(More)
This paper proposes an adaptive global asymptotic stable (adaptive GAS) control scheme for the compensation of friction and disturbance effect to control robot manipulators. This control method integrates both model reference technique and exact linearization. In addition, it employs disturbance compensating mechanics to control the system to follow a(More)
