This article mainly describes Remote communication system Base on GPS/GPRS technology in construction machinery, and focus on introducing the technology of data transportation between machine ECU with GPS terminal and remote control machine via RS232 serial communication circuit. In this way it provides monitoring machine online and prevents GPS terminal from removed in Construction machinery. Currently many machinery suppliers have adopted finance lease to push selling in domestic market, In order to secure selling from financial risk and guarantee monitoring machine running information, GPS/GPRS technology integrated in Construction machinery becomes one of the essential marketing measures.

This paper describes the design and development of remote communication system for mines detector robot. This project uses a PIC18F4580 microcontroller to control the robot movements and functions. A metal detector will be attached to the robot. The robot will have two operating modes; automatic and manual mode. In automatic mode, the robot will move according to a predefined track. When the robot is moving, the system produces feedbacks given by the sensors on the robot to the remote computer about the surroundings and when potential land mines are detected. In manual mode, the robot will be fully controlled by the remote computer for decision making process. All the controls and monitoring of data are displayed in a graphical user interface (GUI). The wireless module proposed is the XBee RF modules. The XBee modules were found to perform with optimum data transfer reliability at the range equals to 25% of its maximum communication range.

After disasters, remote control of construction machinery is often required to ensure the safety of workers during excavation. However, only limited numbers of remote-controlled construction machinery exist, and they are typically larger than conventional machinery. After a disaster, the transportation of such machinery takes additional time and is often troublesome. Therefore, it would be desirable to develop a remote-control system that could easily be installed on ordinary construction machinery. A pneumatic humanoid robot arm is in the process of being developed. While considering the portability issue, a lightweight fiber knitted pneumatic artificial rubber muscle (PARM) was selected as the actuator for the arm. This arm can be installed on all construction machinery models, can be controlled remotely, and has been designed for easy installation and portability. In this research, construction machinery was retrofitted with a pneumatic robot that enables it to be operated remotely. This robot has 6 degrees of freedom and utilizes the fiber knitted PARM. Experiments were conducted to measure the static characteristics of the new PARM and to measure their performance in the remote control of construction machinery. Experimental results showed that the developed system is able to achieve handling two levers of machinery, one that controls back and forward movement and the other that controls the bucket. Experimental results showed that the developed system successfully operated construction machinery remotely.

This paper introduced to develop and implementation of PC based controller for humanoid robot using digital potentiometer. The main objective in this paper is to develop and implement the joystick controller by using a digital potentiometer circuit board that be able to control the humanoid robot movement. The Arduino board and digital potentiometer will be integrated by connecting both pins in between wiper, W pin and ground, GND to the DB9 pins of remote control platform, which is TX and RX pins respectively. Humanoid robot as known as TOMY i-SOBOT is used as a preferred model due to wide usage in many applications. A digital potentiometer will be transmitted the voltage and current value depend on the digital level through serial communication to give the instruction for humanoid robot movement. The humanoid movement based on Guided User Interface (GUI) where the user give a commands by pressing the button on the GUI such as turn left, right, forward, and reverse. The results show that the humanoid movement able to control based on the voltage and current in a digital potentiometers value.

In order to have an optimal production in a Green-house, it is necessary to regulate the artificial micro-environment. By controlling the main physical variables (temperature, humidity, irrigation cycles, etc.) as well as the variables involved in the rates of plants growing (nutrients, sun radiation, water, etc.), the plant’s production quality, the energy and water consumption can be optimized. For instance, temperature and humidity can be regulated by opening or drawing the ventilation system or domes or by heating or circulating the air inside the greenhouse. These tasks should be constantly supervised by a supervised distributed communication system. In this paper, we propose a distributed serial communication system based on microcontrollers to monitoring and supervising the process via Internet, in order to achieve the on-line supervision and control of the greenhouse operation and environmental conditions as well as the main variables (temperature, humidity, irrigation cycles, etc.).
