Festo AG & Co. KG bistable valves for safety-related applications
Festo AG & Co. KG bistable valves for safety-related applications Technical Report - TR-300004

Summary:
Technical Reports 2 and 3 [1-2] and DGUV Information FB HM-076 [3] already explained the circumstances under which bistable valves can be used in safety-related applications. The present report links these reports to the current product portfolio of Festo AG & Co. KG. The suitability of the bistable valves listed for safety-related applications can be confirmed taking the previous series of technical reports and respective technical documentation of the individual components into consideration.

Bistable valves in safety-related applications. An example.
Bistable valves in safety-related applications. An example. Technical report TR-300003

Summary:
Due to their bistable characteristics, bistable valves in certain applications present the user with tasks that seem to be difficult to solve. This application example is to show how a solution can be developed systematically taking the various operating states and operating transitions into account. Considering the various hazards in the various operating statuses of the machine appears a sensible approach to finding the solution. They require chronologically successive, different reactions of the safety circuit to implement the required protective measures.

Dexterous  Manipulation Using Hierarchical Reinforcement Learning
Dexterous Manipulation Using Hierarchical Reinforcement Learning LearningGripper

On a novel pneumatic four-finger gripper with three degrees of freedom per finger we apply reinforcement learning to learn dexter- ous manipulation of objects. In order to reduce the search space, we implemented hierarchical learning on two levels. Low-level learning is used for basic movement primitives like grabbing, lifting or rotation of an object around three cartesian axes, whereas in high-level learning we use the already learned low-level actions to find a policy that ena- bles the gripper to move a target point on the surface of a sphere to the top position in a few seconds. It turns out that Q-learning with a finite state- and action space solves the learning task very well.

The SLS-generated Soft Robotic Hand
The SLS-generated Soft Robotic Hand An Integrated Approach using Additive Manufacturing and Reinforcement Learning

To develop
a robotic system for a complex task
is a time- consuming process. Merging
methods available today, a new ap- proach for a faster realization of a multi-finger soft robotic hand is presented here. This
paper introduces a robotic hand with four fingers and 12 Degrees of Freedom
(DoFs) using bellow actuators. The hand is generated via Selective
Laser Sintering (SLS), an Additive Manufacturing method. The complex task execution of a specific action,
i.e. the lifting, rotating and precise positioning of a handling- object with this robotic hand, is used to structure
the whole develop- ment process. To
validate reliable functionality of the hand from the beginning, each development
stage is SLS-generated and the targeted task execution is trained
via Reinforcement Learning, a machine learning approach.
Optimization points are subsequently derived
and fed back into the hardware development. With this Concurrent
Engineering strategy a fast development of this robotic
hand is possible. The paper
outlines the relevant key strategies and gives insight into
the design process. At the end, the
final hand with its capabilities is presented and discussed.

Inventing a Micro Aerial Vehicle inspired by the mechanics of dragonfly flight
Inventing a Micro Aerial Vehicle inspired by the mechanics of dragonfly flight BionicOpter

Dragonfly flight is unique: Dragonflies can manoeuvre in all directions, glide without having to beat their wings and hover in the air. Their ability to move each of their four wings independently ena- bles them to slow down and turn abruptly, to accelerate swiftly and even to fly backwards. We looked into the mechanics of the dragonfly flight and managed to transfer its flight dynamics into an ultralight flying object: the Bionicüpter. With a wingspan of 63 cm and a body length of 44 cm, the model dragonfly weighs just 175 g. A brushless motor actuates the four wings and is used to alter the flapping fre- quency. Eight servo motors allow the amplitude and the twisting angle of each wing to be changed independently making the Bionicüpter almost as agile and fast as its natural role model. Here we present

how dragonfly flight dynamics can inspire future design of MAVs.

Artificial hinged-wing bird with active torsion and partially linear kinematics
Artificial hinged-wing bird with active torsion and partially linear kinematics SmartBird

An artificial bird is introduced which was developed using two new

features in biologically-inspired flight, active torsion and partially linear

kinematics. Active torsion rests on well established theoretical

predictions in unsteady aerodynamics. The concept of partially linear

kinematics is inspired by zoological observations on flying locusts.

When the wings flap upwards, the servomotor for the active torsion

turns the outer wing from a positive angle of incidence within

a short fraction of the flapping period into a negative angle of incidence.

Between the turning points the angle of torsion remains

constant. Numerical calculations confirm the expected benefits

compared to passive torsion.

White paper Food safety: food quality through high compressed air quality
White paper Food safety: food quality through high compressed air quality

Great care must always be taken when compressed air comes into contact with food, because compressed air is not clean by nature.   On the contrary, solids and particles are present almost everywhere in the form of dust in various concentrations. Water, in the form of natural atmospheric humidity, is released in large quantities when the compressed air cools down. And thus compressed air quality in accordance with the requirements of the respective application provides best possible safety for foods, consumers and food producers.

 

This white paper includes information on:

- Compressed air preparation and compressed air quality classes

- Filter cascades for typical applications

White Paper: The future role of ethernet and the trend to decentralised control solutions
White Paper: The future role of ethernet and the trend to decentralised control solutions field bus / Industrial Ethernet

The driving force behind progress in Industrial automation in the last 20 years has without doubt been the networking of automation products via bus systems. The importance of industrial communication within machines and installations is increasing exponentially, especially in the context of recent Industry 4.0 (Internet of Things, IoT) discussions. Networking is decentralised from its starting point – communication at control system level – down to the connection of front-end devices, sensors and actuators, which perhaps already feature decentralised intelligence.

White paper: Comparative evaluation of automation concepts for water industry systems
White paper: Comparative evaluation of automation concepts for water industry systems Tools for optimising life cycle costs

Energy efficiency and the optimisation of specific production costs are important commercial and business challenges which we must face for a variety of reasons. Energy-efficient technologies are often more expensive than traditional technologies in the investment phase. However, measures to increase efficiency and reduce life cycle costs (LCC) throughout the entire life cycle of a production plant usually pay off.

White Paper: Tips for overall equipment effectiveness (OEE) in food and beverage production
White Paper: Tips for overall equipment effectiveness (OEE) in food and beverage production

Maximum availability is not something that happens by chance, it’s the result of forward-looking action. Processing food economically and at the right time is absolutely essential. Otherwise there is a risk that production has to be stopped and raw materials are wasted.

Taking overall equipment effectiveness into consideration provides clear guidance on how to maximise productivity, and thus on economic operation of the system. But which influencing factors affect overall equipment effectiveness and how to get started on the path to
optimisation?

More productivity with optimally cushioned pneumatic cylinders
More productivity with optimally cushioned pneumatic cylinders White paper

With the right end-position cushioning, you can significantly increase the efficiency of your entire pneumatic system.

When used to its full effect, it can improve cycle times and even reduce the size of the components used.

  

And all this for the simple reason that good end-position cushioning decreases the impact forces generated by changing loads and extreme dynamic stress – factors that play a crucial role in defining the travel time and speed of pneumatic cylinders.
