Abstract

In paper the fundamental question about optimal interaction between the controlling stimuli generated by the active (powered) and the passive (unpowered) drives of the robotic systems have been studied. A mathematical statement of the problem has been proposed that is suitable to study this question for the semi-passively actuated n-degree-of-freedom robotic systems. The problem is formulated as an optimal control problem for n-degree-of-freedom mechanical system models a semi-passively actuated robot. We take into account the inter ....etc

An actuator is a component of machines that is responsible for moving or controlling a mechanism or system.

An actuator requires a control signal and source of energy. The control signal is relatively low energy and may be electric voltage or current, pneumatic or hydraulic pressure, or even human power. The supplied main energy source may be electric current, hydraulic fluid pressure, or pneumatic pressure. When the control signal is received, the actuator responds by converting the energy into mechanical motion.

An actuator is the mecha ....etc

Electroactive Polymer (EAP) Actuators


Electroactive Polymer Technology

Electroactive polymers (EAP) are promising as actuators in intelligent material
systems, where large deformations are required. Electromagnetic, piezoelectric
or shape memory alloy actuators are either too heavy, too complex or too slow
for such applications. EAP however are relatively lightweight, rather simple and
fast enough.
In particular, dielectric electroactive polymers were shown to have good ove ....etc

ELECTROACTIVE POLYMERS(EAP)
ABSTRACT
Electro active polymers are soft actuation materials that are fastly replacing the conventional actuating materials such as piezo electric crystals, motors, screws etc:- As the name suggests, they essentially consists of a ionic polymer back bone metallic composite having positive counter ions. On the application of an electric field or small voltage, these EAP s will bend towards the anode.
They have properties resembling human muscles and ar ....etc
