“…Further applications concern aero-elastic vibration suppression [ 53 ] and mass–spring–damper mechanical systems [ 54 ]. In this field of vibration absorption and vibration control, a phase-based fuzzy logic controller is also proposed by Liao et al [ 55 ]. It is important to note that in current industrial settings, AGVs have to be integrated in the so-called Internet of Things (IoT).…”

In the last decades, virtual sensors have found increasing attention in the research community. Virtual sensors employ mathematical models and different sources of information such as actuator states or sensors, which are already existing in a system, in order to generate virtual measurements. Additionally, in recent years, the concept of virtual actuators has been proposed by leading researchers. Virtual actuators are parts of a fault-tolerant control strategy and aim to accommodate faults and to achieve a safe operation of a faulty plant. This paper describes a novel concept for a fuzzy virtual actuator applied to an automated guided vehicle (AGV). The application of fuzzy logic rules allows integrating expert knowledge or experimental data into the decision making of the virtual actuator. The AGV under consideration disposes of an innovative steering concept, which leads to considerable advantages in terms of maneuverability, but requires an elaborate control system. The application of the virtual actuator allows the accommodation of several possible faults, such as a slippery surface under one of the drive modules of the AGV.

“…Owing to the good mechanical properties of non‐magnetic matrices and the unique magneto‐induced capability of ferromagnetic particles, magnetorheological elastomers (MREs) have promising applications, such as untethered actuation, [ 26,44–49 ] vibration control, [ 50–53 ] and non‐contact sensing. [ 31,36,54–58 ] Under an external magnetic field, the magnetic interactions of the particles actuate the matrix, and the gaps between the conductive fillers and magnetic particles are varied, resulting in changing conductivity.…”

Braille devices made from stimuli‐active polymers have provided a new approach for obtaining information on Braille text. However, it is still essential to find a more convenient and effective method to develop multifunctional Braille devices with shape memory effects to broaden their applications. Here, a novel smart refreshable Braille display based on triple‐shape memory and magnetoresistive composite is developed with the advantages of simple fabrication, multifunctionality, and harmlessness for blind people. The triple shape memory effect enables this device to record the Braille text information and display the text using a complex Braille dot array. The stimuli‐dependent conductivity produces a simultaneous electrical sensing signal when Braille dots are touched, thus the reading areas can be distinguished. Therefore, this multifunctional flexible composite has the potential to realize a refreshable and portable Braille e‐book in the future.
