This paper presents the design of a biped robot using the Cerebellar Model Articulation Controller (CMAC). An inertial navigation system (INS) including gyroscopes and accelerometers is used to measure the robot’s attitude and acceleration for modifying the dynamic attitude of the robot. Moreover, a zero moment point (ZMP) compensator is used to on-line adjust the gait trajectories to improve t...

A rehabilitation robot plays an important role in relieving the therapists' burden and helping patients with ankle injuries to perform more accurate and effective rehabilitation training. However, a majority of current ankle rehabilitation robots are rigid and have drawbacks in terms of complex structure, poor flexibility and lack of safety. Taking advantages of pneumatic muscles' good flexibil...

This paper presents experimental analysis of wheeled mobile robots. Mathematical modelling of the mobile robot is presented. The mobile robots consist of an omni-directional and three differential drive mobile robots are tested and moved in given trajectories and the systematic errors of the robots are determined. A new method for omni-direction mobile robot was introduced in which the robot wa...

Despite recent progress in robotics research and development, the effective design of multi-purpose robotic solutions for civilian and domestic environments has proven particularly elusive. Mechanically simple systems are typically incapable of traversing stairs (a feature in most buildings) and lack the flexibility to undertake many tasks that may be desired while more complex solutions suffer...

One of the most important challenges in nonlinear, multi-input multi-output (MIMO) and time variant systems (e.g., robot manipulator) is designing a controller with acceptable performance. This paper focused on design a new artificial non linear controller with on line tunable gain applied in the robot manipulator. The sliding mode fuzzy controller (SMFC) was designed as 7 rules Mamdani’s infer...

In some situations, when an external disturbance occurs, humans can rock stably backward and forward by lifting the toe or the heel to keep the upright balance without stepping. Many control schemes have been proposed for standing balance control under external disturbances without stepping. But, in most of them researchers have only considered a flat foot phase. In this paper a framework is pr...

In this paper robust PID control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. In dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. To develop the idea of control for cable robots with elastic cables, a robust PID control for cable driven robots with ideal rigid cables is firstly de...

This study presents a sliding-mode neural-network (SMNN) control system for the tracking control of an n rigid-link robot manipulator to achieve high-precision position control. The aim of this study is to overcome some of the shortcomings of conventional robust controllers such as a model-based adaptive controller requires the system dynamics in detail; the fuzzy rule learning scheme has a lat...

When a robot arm(s) conducts some tasks on a satellite, the satellite attitude stability is necessary against the robot arm's motion to maintain the communication link and to generate electrical power from the solar panel(s). However the reaction from the robot arm is much stronger than the natural environmental disturbance torque that the traditional satellite attitude control system cares. Na...
