This situation has attracted the attention of companies and researchers and has accelerated studies on this subject. In this study, an algorithm was developed for the autonomous mobile robot to serve in industrial areas. In line with this study, it was ensured that the autonomous mobile robot mapped the working environment, determined the working station in this environment, and then carried out transport operations between these working stations in accordance with a given work order. After the mobile robot fulfilled the work order, it went into a waiting state until a new work order was received. For the mobile robot to save energy, it was ensured that it waited close to the point where the work order came in the most, by means of machine learning...

A state-space model for the custom designed TWSBR is obtained through dynamic analysis using a Lagrangian method. System identification experiments are proposed and performed to identify the parameters of the model. Based on the identified model, an LQR controller, which is a combination of optimal estimation and optimal control, is designed and implemented that can successfully stabilize TWSBMR. At last, few tests are carried out to evaluate the performance of the controller, showing how the proposed LQR controller outperforms classical controller in many aspects.

The energy consumption is more efficient, especially in the embedded devices fed by the battery, because the charging time is an obstacle to the use of the device. In addition, energy efficiency in terms of power dissipation and system health is important in other embedded applications such as biomedical, test and measurement, industrial control and robots. Reducing energy consumption during the design phase of the embedded system is generally considered as the task of the hardware. In fact, the software should also undertake the task of improving energy efficiency. In this research, the control algorithm of the embedded system is written in two different methods and their energy consumption was compared.

The hardware is simplified with the peripheral feature integrated in controller 8051F350, and reliability is improved. The interface of thermocouple with programmable gain amplifier through A/D converter in mixed signal controller and USB interface with master computer is presented. Keeping an eye on the viability of the complete system as a commercial product, on chip temperature sensor has been considered for sensing the reference junction temperature. The non-linear output compensation and cold-junction compensation of thermocouple is provided by real time embedded software.

This sizing procedure can simulate the annual performance of different kinds of photovoltaic-wind hybrid power system structures for an identified set of renewable resources, which fulfills technical limitations with the lowest energy cost. The output of the program will display the performance of the system during the year, the total cost of the system, and the best size for the PV-generator, wind generator, and battery capacity. Security lightning application is selected, whereas system performance data and environmental operating conditions are measured and stored.

The investigated model is based on photovoltaic and wind generators are connected to a stand-alone system supported by a battery bank. First, the system is sized according to the electric demand and the availability of renewable energy resources. Then, each component of the hybrid power system is dynamically modeled in order to maximize the renewable energy and to analyze the instabilities that affect the energy production. The investigated model needs hourly solar radiation data from the site for the hybrid system and the anticipated load data to predict the general performance of the system. Simulation studies were carried out using MATLAB Simulink software package.
