International Journal of Automation and Smart Technology

International Journal of Automation and Smart Technology (AUSMT) is a peer-reviewed, open-access journal devoted to publishing research papers in the fields of automation and smart technology. Currently, the journal is abstracted in INSPEC and DOAJ (Directory of Open Access Journals). The research areas of the journal include but are not limited to the fields of mechatronics, automation, ambient Intelligence, sensor networks, human-computer interfaces, and robotics. These technologies should be developed with the major purpose to increase the quality of life as well as to work towards environmental, economic and social sustainability for future generations.
This international journal endeavors to provide a worldwide forum for the dynamic exchange of ideas and findings from research of different disciplines from around the world. Also, AUSMT actively seeks to encourage interaction and cooperation between academia and industry along the fields of automation and smart technology.

PAPER INFORMATION

Jwu-Sheng Hu and Yung-Jung Chang, “Simultaneous Hand-Eye-Workspace and Camera Calibration using Laser Beam Projection,” vol. 4, no. 1, pp. 27-42, 2014 (doi:10.5875/ausmt.v4i1.205)

ABSTRACT

This work presents a novel calibration technique capable of simultaneously calibrating a camera’s intrinsic parameters and hand-eye-workspace relations. In addition to relaxing the requirement of a precise calibration reference to achieve manipulator accuracy, the proposed method functions when the hand is not in the view field of the eye. The calibration method uses a laser pointer mounted on the hand to project laser beams onto a planar object, which serves as the working plane. Collected laser spot images must adhere to certain nonlinear constraints established by each hand pose and the corresponding plane-laser intersection. This work also introduces calibration methods for two cases using single and multiple planes. A multistage closed-form solution is derived and serves as the initial guess to the nonlinear optimization procedure that minimizes errors globally, allowing the proposed calibration method to function without manual intervention. The effectiveness of the proposed method is verified by comparison with existing hand-eye calibration methods via simulation and experiments using an industrial manipulator.

ABSTRACT

Continuous increases in fuel prices and environmental awareness have raised the importance of reducing vehicle emissions, with many national governments passing anti-idling laws. To reduce air pollution and fuel consumption, we propose a frequency-based vehicle idling detection method to remind drivers to turn off the engine vehicle idling exceeds a certain time threshold. The method is implemented in existing handheld devices without any modification to the car or engine, making the solution cheap and simple to implement in any type of motor vehicle. Experimental results show the proposed method can effectively differentiate idling, engine-off, and moving conditions. Two implementation cases are presented to demonstrate the feasibility and performance of the proposed method.

Editor’s Choice in AUSMT December Issue

The research highlight selected by our Guest Editor, Prof. Kuo-Shen Chen, is “Precision positioning with shape-memory-alloy actuators”. In this work, good positioning performance of shape-memory-alloy actuators was achieved by (1) utilizing an inverse hysteresis model to reduce the system’s nonlinearity so that the system can be modeled as a linear model, and (2) constructing the corresponding model-reference-adaptive-system (MRAS) based on this linear model.

PAPER INFORMATION

Kai-Hung Liang, Kuo-Han Kao, and Szu-Chi Tien, “Precision positioning with shape-memory-alloy actuators,” vol. 3, no. 4, pp. 265-271, 2013 (doi: 10.5875/ausmt.v3i4.209)

ABSTRACT

The primary purpose of this study is to improve the positioning performance of shape-memory-alloy (SMA) actuators. In order to achieve this goal, the system nonlinearity was reduced with the inversion of a nonlinear model. The system could then be approximated with a linear model. It is easy to construct the corresponding model-reference-adaptive-system (MRAS) based on this linear model. Experimental results show that the MRAS is robust with respect to external disturbances and improves the positioning performance. In addition, with the proposed control scheme, the simulation results will closely match experimental results, which is useful to predict the system performance at the controller-design stage.
