Festo robotic projects


Airic's arm is a robot arm with artificial bones and muscles. A total of 30 muscles move the bone structure which , as with our own arms, consists of ulna and radius , metacarpal and finger bones, a shoulder joint and a shoulder bone-joints that are otherwise not encountered in this form in the world of technology. They were designed on computer and are grown in a three-dimensional polyamide structure using a state of the art laser sintering process.

The muscle, a product of Festo, are already widely found in industrial application under the name of Fluidic Muscles. These are tubes of elastomer reinforced with aramide fibers. When a Fluidic Muscles is filled with compressed air, its diameter increases and it is simultaneously shortened.

Using this technology, in conjunction with Festo’s tiny, highly innovative piezo-proportional valves, it is possible to precisely regulate the forces and rigidity within the construction. These actuators can be coordinated using state-of-the-art mechatronic systems and software.

The possibility of enhancing the Airic’s_arm sensors in the future, for instance by adding cameras or tactile perception elements, is just as feasible as the possibility of a further development in the form of back, hip and neck. Enhancements of this type will also be useful in robotics, as they could be used to assign even more hazardous tasks to technology.


Aqua_ray is a remote-controlled fish driven by water hydraulics, the shape and movements of which have been based on the model of a manta ray.

The central drive and control unit of Aqua_ray takes the form of a Festo Fluidic Muscle. This is combined with the Fin Ray Effect®, a design based on the functional anatomy of a fish’s fin that makes it possible to imitate the fin drive of the natural role model almost perfectly.

As the Aqua_ray can be manoeuvred extremely well, and can be operated both as a hydrostatic glider and with an active wing beat, substantial energy savings can be achieved. Thanks to its shape and method of movement, the Aqua_ray can be used in wide ranging areas of oceanography, without disrupting the natural environment.


Air_ray, modelled on the manta ray, is a remote-controlled hybrid construction consisting of a helium-filled ballonet and a beating wing drive. Its light design makes it possible for it to “swim” in the sea of air, boosted by helium, in a similar way to the manta ray in water.

Propulsion is achieved by a beating wing drive. The servo drive-controlled wing, which can move up and down, utilises the Fin Ray Effect® and is based on alternate pulling and pushing flanks connected via frames. When pressure is exerted on one flank, the geometrical structure curves automatically against the direction of the influencing force. A servo drive pulls the two flanks alternately in the longitudinal direction, thus moving the wing up and down.
