AbstractThe study determines the feasibility of a new actuation system that couples a fluidic artificial muscle designed by Festo [1] with a metal hydride hydrogen compressor to create a compact, lightweight, noiseless system capable of high forces and smooth actuation. An initial model for the complete system is developed. The analysis is restricted in some aspects concerning the complexity of the hydriding/dehydriding chemical process of the system and the three-dimensional geometry of the reactor, but it provides a useful comparison to other actuation devices and clearly reveals the parameters necessary for optimization of the actuation system in future work. The system shows comparable work output and has the benefits of biological muscle-like properties [2] for use in robotic systems. When compared to other previously developed metal hydride actuation systems the potential for increasing the reaction kinetics and improving the overall power output of the system is revealed. A comparison of the system to common actuation devices, including a biological muscle, shows similar stress and strain relations, but a lower power and frequency range due to the slow actuation time. Improving the reaction kinetics of the system will be the first approach to enhancing the system, along with optimization of the mass and type of metal hydride used in the reactor to produce a full actuation stoke of the fluidic muscle while minimizing system weight.

Promising Type

The newest and most promising type of pneumatic actuators is the pneumatic artificial muscle (PAM). Different designs have been developed, but the McKibben muscle is the most popular and is made commercially available by different companies (e. g. Fluidic Muscle manufactured by Festo Company). The most often mentioned characteristic of PAMs is the force as a function of pressure and contraction. In this paper our newest function approximation for the force generated by Fluidic Muscles is shown that can be generally used for different muscles made by Festo Company.

The paper shows the results of a theoretical and experimental research activity oriented to the design and the realization of a of a low cost pneumatronic prototype, proposed for tasks of pipes and ducts inspection. Geometries and sizes of ducts are significantly different and for their inspection very flexible units are needed. Different researchers propose several solutions: the present proposal is specifically oriented to an automated pneumatic low cost unit. The prototype is conceived to emulate the grub’s motion: variable geometry components are deformed under the action of pneumatic power supply, following a programmable logic actuation. A fluidic muscle is used to generate the motion and two deformable air chambers are arranged at the ends of the muscle in order to assure the anchorage to the internal pipe wall. The automatic phases of the motion are managed by an external micro-PLC, allowing flexible and bi-directional motions. The unit is equipped with a micro-camera and can be also equipped with micro grippers and micro mechanical tools. The design and the optimization of the prototype’s mechanical structure is discussed and related to the mechatronic approach applied to perform the cyclical movement.

Fluidic Muscle

Pneumatic artificial muscles (PAMs) are of special importance in the field of pneumatic drives and in robotics. Different designs have been developed, but the McKibben muscle is the most popular and is made commercially available by different companies, e.g. Fluidic Muscle manufactured by Festo Company. There are a lot of advantages of PAMs like the high strength, good power/weight ratio, good power/volume ratio, low price, little maintenance needed, great compliance, compactness, flexibility, inherent safety and usage under rough environments. The objective of this research note is to determine the error of positioning with a Fluidic Muscle at cold and at normal operating temperature of the system with sliding mode control. The results of the experiments showed that the positioning error of the Fluidic Muscle under the experimental conditions was 0.01 mm.
