This paper introduces a new type of actuator, namely Electro-Hydrostatic Actuator (EHA) [1] . According to the engineering, we choose the asymmetric hydraulic cylinder, establish the mathematical model of permanent magnet synchronous motor and EHA, and adopt the MATLAB proceeds to imitate the true research. To solve the problem of nonlinear system, we adopt PID control method.
It is difficult to establish a more accurate dynamic model of bicycle robot which is a nonlinear, time-varying, ambiguity of system, uncertainty, etc, While precise model of complex system often requires more complex ...

Use of robotics and computerized tools in Nuclear Power Plants (NPPs) has been identified as a highly recommended practice by IAEA. The key rationale of robotics application has always been to avoid human exposure to hazardous environments and tasks ranging from scrutiny and general maintenance to decontamination and post accidental activities. To execute these activities, robots need to incorporate artificial intelligence, improved sensors capability, enhanced data fusion and compliant human like leg and hand structures for efficient motions. Next generation robotic systems in NPPs are expected to work in full autonomous mode in contrast to the current semi-autonomous scenarios. Far future systems could deploy humanoid robots as well. This paper presents state-of-the-art of robotics developed for NPPs, associated challenges and finally comments on future directions.

The semi-automatic machines that employees use must work continuously. Body and eye fatigue impactsemployeesperformance and causes damage to thefinal product. The automatic machine worksuntil the task is completed. The amount of time used is re-program depend on how different between task change. If the path or motion of automatic machine is change, the re-program time is likely to be long. If there are changes to tasks,the only time lost is in re-programming the automatic machine. Therefore, this paper is using computer vision to solve the problem of the automatic machine motion when it must be move from point to *** process will be recorded and the image analyzedto find the points of robot *** finding these points,the solution uses the 'Traveling Salesman Problem' to control the robot motion to find the shortest path from point to point.

The production system in industry in Thailand is still having various problems due to the uncertainty of production, or the work characteristics that is required to be done repeatedly. For instance, surface finishing of a work piece that result in unsteady production quantity, Due to this it is hard to plan for production. This kind of work makes the use of robots instead of people which is a better solution. This research presents the idea of bringing the Articulated Arm robot that covers a wide area of the work field and that can be applied in various types of use. The end-effector will have controlled movement on the surface of the work piece and will analyze the CAD file of the work piece to find the variable of each joint of the work surface. Then, using the mathematical model to process and write the information in the language of the control machine so that the robot will move on the work surface as set in CAD file and the finished piece will have a smooth surface as designed.
The objective of this project is to develop a Quadrupedal (four legs) robot with speech recognition to control the movement. There are only three words of command to be recognized, which are "forward", "...
