Lower extremity exoskeletons are wearable robots that integrate human intelligence with the strength of legged robots. Recently, lower extremity exoskeletons have been specifically developed for transportation of disabled individuals. This paper summarizes the anthropomorphic design of a lower extremity exoskeleton named “walking supporting exoskeleton (WSE).” WSE has been developed to support some...
In this study, a technique is proposed for dynamic modeling and adaptive network based interval type2 fuzzy logic (ANIT2FL) position, vibration and oscillation control of a single flexible link robot manipulator carrying a pendulum at the tip end. Simulation model for a single flexible manipulator carrying pendulum system is designed as an observer to determine motion of flexible link and uncertain...
In this study position and vibration control of a rigid-flexible robot manipulator is investigated. Initially dynamic model of the manipulator system is obtained by using Lagrange equations and assumed modes method. Two adaptive networks based fuzzy logic controllers (ANFLCs) are proposed for tracking control of the rigid link and the flexible link. The training and testing data of ANFLCs are obtained...
In this study, a fuzzy logic controller is designed in order to use in trajectory control of a robot manipulator. The considered robot manipulator consists of a rotating-prismatic joint housing a sliding flexible arm that carries a concentrated mass at the tip end. The tip end of the flexible arm traces a multi-straight-line path. This study is aimed to use a fuzzy logic controller in controlling...
In this study, interval type2 fuzzy logic (IT2FL) and PID controller is designed for swing-up position control of double inverted pendulum (DIP) system. The double inverted pendulum system consists of two rigid bars connected by a revolute joint. Mass of the revolute joint is included in the dynamic model.Rigid bars in the system are assumed to experience planar motion. The pendulum system is connected...
