All around the aviation world, there are various different size national and international organizations which study the aviation safety and which issue standards, regulations or guidelines. But there is no industry document which completely covers all requirements of a complete flight deck alerting system [1]. Mostly the contents are similar in the documents, but somehow there are missing parts in...
We have previously shown that microparts can be fed along an asymmetric microfabricated surface using simple planar symmetric vibrations. Microparts move forward because they adhere to the microfabricated surface asymmetrically. We have also described the effects of sawtoothed surfaces on the movement of submillimeter microparts; for example, 0603 (size, 0.6 × 0.6 × 0.3 mm; weight, 0.3 mg) and 0402...
In this paper we propose an onboard software framework for many types of remote systems with the capability of dynamic self-update without halting the software or shutting the hardware system, which are necessary for conventional onboard software updates. The key idea is to express an operational plan, which is usually a sequence of system-built-in commands, as a text script. This script contains...
The vibration suppression of semi-actively controlled jacket-type offshore platforms using Magnetorheological (MR) dampers is studied. The main goal of using MR damper system is to reduce vibration caused by wave hydrodynamic forces. A fixed jacket-type offshore platform affected by wave-induced hydrodynamic forces and controlled by MR dampers is modelled as a semi-active controlled system with 30...
Driver assistance systems are expected to reduce the possibility of accidents caused by impaired or reckless driving. However, the current designs employed in some luxury cars are not entirely reliable and may even lead to more distraction of the driver. This paper presents the idea of an overriding controller for lateral control of a vehicle in a driver assistance system. In the proposed system,...
This paper initiates the launch and the integration of a new scientific concept: “Mechatronics galaxy”, a support of industrial research for European sustainable and strategic development
This paper focuses on the problem of disturbance compensation in motion control. Disturbance observer (DOB) and sliding mode control (SMC) are both famous approaches to solve the problem. However, the DOB does not deal with nonlinear disturbance sufficiently. The SMC has chattering phenomenon which limits its application. In this paper, the idea of sliding mode assist disturbance observer (SMADO)...
This paper presents a practical control methodology of force control systems using a pneumatic cylinder for polishing machines. The typical machine is composed of the pneumatic cylinder as an actuator, a motor to rotate a whetstone, and a force sensor to detect the force value, where the high precision force control is required to achieve the high precision polish for objects. Vibration generated...
The intelligent mechatronic equipment is structured on a checking table on which the main shaft is mounted between a running centre with rolling elements and a precision bushing with canals and 4 slides on rolling guides with compressed-air buffers on which the checking gears are mounted for detecting the shocks and axle base. The teeth shaft and checking gears in contact are driven into a rotation...
The scope of the crankshafts fatigue testing is to determine their superior strength limit for a number of 107 cycles during an established moment of deflection of approx. 75 daNm, their behaviour at 2,5×106cycles and their resistance to rupture (WOHLER diagram).
The intelligent machine is designated to measure the dimensions c=144,2 mm, dce=92,lmm, k=17,1mm and dcs=112mm and to mark automat of these heights with the other data of identification (type of piece, series, date etc). Mechatronic intelligent measurement determines and verifies the real dimensions in view to fit the conic assembly (the selection of the space-rings dimensions that will be mounted...
This paper proposes an estimation method of the arrangement of sensing points in parallel multi-degrees-of-freedom bilateral motion control system. The arrangement of sensing points can be estimated by bilateral motion control for grasping motion based on modal decomposition with Discrete Fourier Series Expansion (DFS). Even if the arrangement of sensing points in master system or slave system is...
In this paper, an algorithm for automatic interlocking table generation and its implementation is introduced. The specially developed software generates an interlocking table conforming to Turkish Railway regulations. Pseudo codes of the method and their descriptions are given. The method is demonstrated on a small station area, and sample outputs are presented.
The work presented in this paper is motivated by the use of haptics in applications of medical simulation, particularly simulation of surgical procedures in hard tissue such as bone structures. In such a scenario haptic device characteristics such as stiffness, motions, suitable workspace and device footprint are key design factors. This paper presents a procedure for optimal design of a parallel...
The simulation modeling and the control of real plant are two - very often separated - flelds of mechatronic practice, research and education. The deep gap between simulation world of controlled system and practical implementation in e.g. embedded hardware can be bridged through the use of special hardware and software directly in MATLAB/Simulink environment. This paper presents the review of available...
The term “Bioinspired” represents translation of any idea, structure, process, and/or material from biological domain into engineering domain to increase human comfort. Creative and innovative engineering processes and products are the expected outputs of this approach. A systematic Bioinspired Design (BID) methodology is required to guide the translation process. This paper introduces a preliminary...
This paper presents the development of scaled four-wheel steering and driven (4WS/4WD) vehicle ideally suited as a research and educational platform in mechatronics. Basic kinematic and dynamic models are presented as the base for vehicle computer simulation as well as for the parameter estimation using variants of Kalman filter. Further the structure of control and power electronic system is briefly...
This paper presents a method of limiting referential joint torques so as to prevent tipping, sliding, twisting and excessively large ground reaction forces(GRF) at the foot This method only requires the referential torques, the manipulator Jacobian and the force sensor data as input, a ZMP trajectory is not necessary. The method works by using joint space position control and workspace force control...
In this paper we present work on fast biped walking. We give an overview of our real-time planning and control system and present experimental results of the robot Lola walking at 3.34 km/h. The basic control approach is based on real-time trajectory planning using a reduced robot model and a stabilizing controller that manipulates the contact forces. Unique features of the system include the real-time...
