2016 11th France-Japan & 9th Europe-Asia Congress on Mechatronics (MECATRONICS) /17th Internationall Conference on Research and Education in Mechatronics (REM)
In this paper, an optical remote control of a digital actuator array is introduced. Driven by a field-programmable gate array (FPGA) based systems, the control permits an electromagnetic actuator to move in response to the reception of serial displacement orders through a wireless optical link. This optical communication is based on a laser diode for emitting the different orders and a selective photodiode...
This paper deals with the need for changes in the way to teach mechatronic engineering design, in order to take into account the increasing development of Cyber-Physical Systems (CPS). After discussing the similarities and differences cited by the scientific community, we present our ongoing educational process to extend the mechatronic system design with the constraints of systems in a CPS context...
This paper concerns a thermomechanical model describing the assisted two-way memory effect of a helical spring. This model takes into account the phase transformation kinetics. A particular attention is paid on the effect of R-phase transformation. The proposed model is validated using experimental results.
There is kinematics analysis, leading to determination of center of gravity location for 4-legged walking robot presented in the paper. Forward kinematics equations for all the legs was derived. The mappings from the local leg frames to global frame located in the chassis center of gravity were proposed and derived. The Quadrapod robot by Lynxmotion was considered as the base for all the computations...
Circadian rhythms (CRs) of human have a role to maintain our mind and body together with our health. Thus, a disorder of CRs is a serious problem because it evokes critical disease. In this society, we have a lot of factor that causes a disorder of CRs, such as a social stress and a light of smartphone in the night. Hence, observing our CRs ourselves is an efficient method to prevent it. We are supposed...
Nowadays, industrials are looking for models and methods that are not only capable to support efficient production performances, but also reactive systems facing an increasing set of unpredicted events and perturbations. For this reason, manufacturing control systems must include mechanisms that cope with the complexity and unpredictability related with disturbances and perturbations that may appear...
The production and rearing of knockout mice, which are house mice with targeted congenital deficiency, contributes greatly for the advances of health science and genetic technology. The mouse with deficiency in the gene possesses the characteristic such as compromised immune system. Meanwhile, partial of the genes of the knockout mouse are intentionally compromised, yet the level of physical fitness...
During flight, the aircraft mass repartition has a deep impact on its stability together with the landing phase. As far as landing is one of the most critical phase of a flight, before taking off, pilots have to take care of the aircraft's center of gravity, by estimating masses and their repartition. Aircraft owners also would like to be informed of landing gears wear, so predictive maintenance would...
Structure from Motion (SfM) is a technique for 3D reconstruction using a single camera. The absolute scale of objects cannot be reconstructed by the conventional SfM. Recently, a method of SfM that can reconstruct the absolute scale has been proposed using refraction at the boundaries of a transparent plate in front of an ordinary camera. In this research, we develop a new method of scale reconstructable...
In this paper, a high-speed three-dimensional map generation method using direct estimation of the motion parameters of the sensor is proposed. Range images are aligned between frames after estimating the motion parameters of the sensor using the relationship of the range image and the motion parameters of a small motion. A 3D map can be created quickly because the method does not need to obtain the...
Agile procedures (e.g. Scrum) are applied in software engineering increasingly. These procedures enhance interdisciplinary collaboration, improvements of lead times and reduction of development costs. Hence, latest research activities are transferring such flexible techniques into machinery and plant construction, in order to cope with the rising software integration into mechatronic modules. As agile...
This RoBO-2L is an Open-Source Matlab Toolbox, which allows to control KUKA industrial robots with the standard Matlab Environment. By its use, the restricted amount of the original program commands is extended through the broad command set of a modern programming language. Complex programs can be organized and implemented much easier. Additionally the systems becomes open for the integration of a...
The article is concerned with the method, which makes it possible to determine optimal values of phase balancing coefficients for steel-making electric arc furnaces. Application of this method will contribute to setting electrode positioning control system in accordance with the design features of the furnace, thus resulting in improving the total energy efficiency of the electrotechnical complex...
We have been developed several kinds of mechanism construction system for over eighteen years. The basic concept for the system is A) easy operation even novice can handle, B) mechanism elements are assembled by seeing screen with keyboard and mouse operation. In the system models are created by 3D CAD and placed in the 3D space and assembled with the other models. The accomplished mechanism structure...
There are several challenges in teaching Systems Engineering to students. The discipline requires projects that are large and complex in order to be able to apply it successfully and for students to see the added value of the methodology. Furthermore, it can be rather process-oriented and the process description can vary, depending on the literature that is being used. However, looking more closely...
This article presents the modeling of an electromagnetic smart surface and the simulation of the pallets displacement on this smart surface. This smart surface is a conveyance system that consists of a fixed coils platform and moving pallets. The platform is composed of a coil cells matrix, where each cell is independently supplied. It allows to independently move several pallets within the platform...
In this study, we developed and validated a new interference reduction method for measuring orientation with a three-axis analog accelerometer. In yaw-pitch-roll order (ZYX convention) Euler angles, roll and pitch are commonly used to represent the tilt of an object. Measuring these angles with an analog accelerometer is a good choice if we can suppress electromagnetic interference. However, the existing...
This paper describes a test bench for rocket engines for educational purposes and small research launchers. Students can develop their own propulsion systems and test them under realistic process conditions. The test bench is equipped for solid combustion as well as for hybrid engines with solid propellant and gaseous oxidizer.
