This article details the SFX-EH architecture for handling sensing failures in autonomous mobile robots. The SFX-EH uses novel extensions to the generate-and-test method to classify failures with only a partial causal model of the sensor/environment/task interactions for the robot. The generate-and-test methodology exploits the ability of the robot as a physically situated agent to actively test...

Transducers are sensors and actuators in order that a computer system can interact with the physical environment. An intelligent or smart transducer is the integration of an analog or digital sensor or actuator element, a processing unit, and a communication interface. In this paper we describe the basic design principles for smart transducers and compare two smart transducer interface standard...

A novel architecture for a parallel Schönflies motion generator was recently proposed, consisting of a CRRHHRRC linkage. The novelty of this architecture lies in its simplicity, as it comprises only two limbs, thereby forming a single-loop closed kinematic chain. Reported in this paper is a realization of this architecture, intended for the production of a proof-of-concept prototype. The realiz...

Hydraulic actuator has been widely used in industrial applications due to its fast response and capability of moving heavy load. The nonlinear properties of hydraulic cylinder had challenged researchers to design a suitable controller for position control, motion control and tracking control. Based on these problems, we had done a real-time digital tracking control studies on electrohydraulic c...

Fault diagnosis and failure prognosis are essential techniques in improving the safety of many manufacturing systems. Therefore, on-line fault detection and isolation is one of the most important tasks in safety-critical and intelligent control systems. Computational intelligence techniques are being investigated as extension of the traditional fault diagnosis methods. This paper discusses the ...

This study aims to improve the performance of a pneumatic positioning system by designing control based on Fuzzy Fractional Order Proportional Integral Derivative (Fuzzy FOPID) controllers. The system’s mathematical model was obtained using identification approach, and FOPID controller optimized PSO algorithm achieve balance between robustness. compared that PID through real-time experimental r...

In recent years, DC power supply and distribution technology plays an increasingly significant role in systems with a low loss large radius. However, the corresponding network protection electric devices cannot satisfy needs of existing network. Based on this, this article, intelligent/energy-efficient leakage circuit breaker based two-phase magnetic nanomaterials detection control is proposed....

A new type of intelligent hanger was designed based on single chip and Pro-E software. 3D entity model of actuator and cover curtain mechanism are established by Pro-E. Wings structure of hanger mechanical part was adopted screw rod and motor combination of the lifting mechanism can make the wings outspread and fold, unique cover curtain structure was adopted. Cover curtain rolls up and down th...

The IEEE 802.15.4 and Zigbee are protocols aimed at low-duty and low-power wireless sensor networks. Continuously monitoring applications such as applications of structural health monitoring could benefit from low power consumption of the IEEE 802.15.4 radio chips. However, existing implementation of IEEE 802.15.4 has limited applicability to ‘proactive’, high-traffic monitoring sensor networks...

The methods of multi-DOF actuator orientation detection based on machine vision and magnetic field sensor and neural network based multisensor fusion are presented in this paper. Special grid pattern is printed on the surface of rotor according to the pseudo-random encoder for the camera capturing the image of the rotor. The magnetic field sensors are adopted and properly placed circling the sh...
