Inflatable manipulators open new trends in robotic applications. In this paper, a new inflatable actuator to articulate a long-range inflatable robotic arm, is presented. Completely made of high strength fabric, its low mass leads to large force-weight ratios and a stroke almost equal to twice its overall length. The operation principle, as well as the relations among the displacement, the pressure...
Design and fabrication of micro mechanical actuators is very useful for special robotic applications. One of the practical usages is continuum manipulators uses in medical applications such as endoscopy tool. In such applications, a maneuverable thin and flexible manipulator is highly required. In this paper, a basic module is studied for such an application. In the structure of module, three wires...
Soft fluidic actuators consisting of elastomeric matrices with embedded flexible materials are of particular interest to the robotics community because they are affordable and can be easily customized to a given application. However, the significant potential of such actuators is currently limited as their design has typically been based on intuition. In this paper, the principle of operation of these...
In this paper, the dynamic model of an active truss structure configured two active piezoelectric members is established, and an experimental modal analysis is completed by means of d-SPACE control system. From the experimental results, it can be seen that the difference of modes of the active and passive trusses is remarkable. Under a proper control law, the frequencies, mode shapes and damping ratios...
