In this paper, we present a real-time Human-Robot Interaction (HRI) system for a service robot based on 3D human activity recognition and human-mimicking decision mechanism. A three-layer Long-Short-Term Memory (LSTM) network is trained to recognize human activity. The input of this network is the 3D skeleton joints information captured by Kinect VI and the output of this network is the class label of human activity. Moreover, the human-mimicking decision mechanism is also fused into the online test process of human activity recognition, which allows the robot to instinctively decide whether to interrupt the current task according to task priority. The robot can make appropriate responses based on aforementioned analytical results. The system framework is realized on the Robot Operating System (ROS). The real-life activity interaction between our service robot and the user was conducted to demonstrate the effectiveness of developed HRI system.

Maintaining suitable environmental conditions like soil moisture, temperature, humidity etc. is required for good crop produce in industrial greenhouses. Internet of Things (IoT) can enable a complete remote visualisation and control of greenhouse environmental parameters in real time. The state of art systems use zigbee based wireless sensor networks for monitoring and control, which have a limited range of operation, bandwidth and cognitive abilities. This paper presents a novel IoT based system for telemetry and control of greenhouse environment. The developed system provides real time wireless sensor data transmission, data visualization and processing at the central monitoring server / PC via ThingSpeak cloud and ubiquitous GSM infrastructure. The use of lightweight and fast Blynk IoT platform for implementing the mobile app for messaging and control of greenhouse environment is a key feature of the developed system. Real time irrigation needs are received via messages on the Blynk app installed on the mobile phone. The experimental results show that the proposed system is an effective solution for energy efficient smart farming in greenhouse and thus contribute towards a sustainable and green environment.

The ability to rapidly drill through diverse, layered materials can greatly enhance future mine-rescue operations, energy exploration, and underground operations. Pneumatic-percussive drilling holds great promise in this area due to its ability to penetrate very hard materials and potential for portability. Currently such systems require expert operators who require extensive training. We envision future applications where first responders who lack such training can still respond rapidly and safely perform operations. Automated techniques can reduce the dependence on expert operators while increasing efficiency and safety. However, current progress in this area is restricted by the difficulty controlling such systems and the complexity of modeling percussive rock-bit interactions. In this work we develop and experimentally validate a novel intelligent percussive drilling architecture that is tailored to autonomously operate in diverse, layered materials. Our approach combines low-level feedback control, machine learning-based material classification, and on-line optimization. Our experimental results demonstrate the effectiveness of this approach and illustrate the performance benefits over conventional methods.

The research paper presents an innovative and novel approach to improve the present plowing methods used in traditional cultivation. The focus is made on reducing labor and the time required in farming. An automatic farm plowing navigation device is made that can be mounted on the top surface of the vehicles used for plowing. The device marks the parameters of land to be cultivated and then directs the vehicle to cover the respected cultivatable area. The hardware components include line lasers for marking the perimeters of the land, potentiometer based angle measuring device for calculating the required distance from the vehicle to the boundaries, Arduino as the microcontroller, relay-based control device to automatize the navigation, LCD for display and hex keypad for data entry. The overall approach is different from popular trends that employ various modish technologies like machine learning, computer vision and artificial intelligence for automating things.

Localisation algorithm with node selection under power constraint in software-defined sensor networks

In this study, the authors propose an improved localisation algorithm in the software-defined sensor networks (SDSNs). This algorithm includes a node-selection strategy under the whole network power constraint, based on the software-defined networking (SDN) technique for providing the centralised control of the network. The analogous Cramer-Rao lower bound (A-CRLB) value is derived for each participating node, which represents a fundamental bound on the variance of the position estimator and is used to evaluate the contribution of each node to localisation accuracy. On the basis of A-CRLB values, the most helpful nodes for localisation are selected to maximise the sum of the nodes' contributory values to the localisation accuracy. With the global network knowledge provided by the SDN controller in the SDSN, the node-selection strategy is formulated into a 0-1 programming problem on the premise of power satisfaction of each node. Furthermore, the proposed node-selection -based localisation algorithm is applied to both noncooperative and cooperative localisation scenarios. Simulation results show that the proposed algorithms provide efficient and effective localisation schemes in SDSNs, and can improve the performance in terms of both the selection convergence speed and the localisation accuracy.

Electric system operators are increasingly concerned with the potential system-wide impacts of the large-scale integration of distributed energy resources including voltage control, protection coordination, and equipment wear. This prompts a need for new simulation techniques that can simultaneously capture all the components of these large integrated smart grid systems. This study describes a novel platform that combines three emerging research areas: power systems co-simulation, power hardware in the loop (PHIL) simulation, and lab-lab links. The platform is distributed, real-time capable, allows for easy internet-based connection from geographically-dispersed participants, and is software platform agnostic. The authors demonstrate its utility by studying real-time PHIL co-simulation of coordinated solar photovoltaic (PV) firming control of two inverters connected in multiple electric distribution network models, prototypical of US and Australian systems. The novel trans-pacific closed-loop system simulation was conducted in real time using a power network simulator and physical PV/battery inverter at power at the National Renewable Energy Laboratory in Golden, CO, USA and a physical PV inverter at power at the Commonwealth Scientific and Industrial Research Organisation's Energy Centre in Newcastle, NSW, Australia. This capability enables smart grid researchers throughout the world to leverage their unique simulation capabilities for multi-site collaborations that can effectively simulate and validate emerging smart grid technology solutions.

Eddy current testing (ECT) is one of the non-destructive evaluation techniques widely used, especially in oil and gas industries. It characterized noisy data to the less-than-perfect detection and as an indication of serious false alarm problem. However, not many researchers have described in detail the intelligent ECT crack detection system. This paper introduces a review of ECT technique and factors that affect the signal fundamental according to the hardware and software development. First, describe the magnetic excitation resources including the sinusoidal and pulse exciting signal. Second, outlines explanation about the ECT probe. The explanations are more about the probes development for air core probe and giant magnetoresistance probe. Third, there is discussion on ECT circuit that used including ECT system, ECT rotating magnetic field and application measurement for optimal control parameters. The defect in characterizations and measurement are discussed on the fourth part of this paper. The fourth part discusses the ECT lift-off compensation including the lift-off and application of intelligent technique in ECT. The limitations of lift-off for coil probe and compensation techniques also discussed in this part. Finally, a comprehensive review of previous studies on the application of intelligent ECT crack detection in nondestructive ECT is presented.

Model-driven real-time control coordination for distribution grids with medium-scale photovoltaic generation

Increasing penetration of photovoltaic (PV) generation may significantly impact existing voltage regulation schemes. In particular, the lack of coordination between control devices and fast change in PV generation can cause voltage magnitude to go beyond limits. This study addresses the issue by providing a novel real-time centralised voltage control algorithm to tackle voltage fluctuations caused by variability of PV power generation. The new method considers autonomous response of upstream voltage regulation devices and provides optimised set-points for the chosen downstream controllers. Furthermore, the investigated method was tested in the real-time digital simulator on a model of 11kV grid located in a semi-rural area of Queensland, Australia. The control algorithm was designed in MATLAB with a multidimensional, non-linear, mixed-integer optimisation. The parallel computing implementation of the KNITRO optimiser helped to provide quicker and more accurate response than the existing uncoordinated control schemes. As a result, optimised control coordination leads to a substantial reduction in voltage fluctuations and decrease in regulation time. Moreover, the proposed method detects and eliminates unnecessary control operations. Thus, it can also prevent voltage hunting in distribution networks.
