This paper presents compare results performance between two conventional controllers for bicycle robot. The bicycle speed control system was a highly nonlinear model multivariable and absolutely unstable. It has used for testing various design control techniques for low power. The objectives of this paper had to developed speed control which derived the mechanic model and experiment. Controllers are Proportional-Integral-Derivatives (PID) and on-off dynamic control. The dynamic system which also includes not stable friction effects the linear zed system model is used as a basis for the design to apply to speed. Computer simulation and experiment have been done controller are capable to control output speed wheel control system successfully. The results show PID controller better then on-off dynamic controller.

Nowadays many robot approaches to robust control problems are applicable only to linear systems for nonlinear systems; we may not be able to easily compute the solution to the optimal control problem as analytical solutions may not be available problem is that statically-stable wheeled mobile robots can easily become dynamically unstable. If the center of gravity is too high or the robot accelerates/decelerates too rapidly or is on a sloping surface so the power supply are necessary for input to actuator robot. This paper presents mode control solutions in power supply for support Omni mobile robot. The performance compare between Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) in Power supply. The experiment on the 5V/50W 100 KHZ prototype CCM and DCM converter which have been designed and builted with similar circuit layouts and component. Aspects to be compared are stability voltage and ripple factor. The both operation mode are discussed based on the simulation and experimental result.

In this article is present to works mention of the robot team of Rajamangala University of Technology Phar Nakhon since 2004 to 2009 by Mr.Nattapong Phanthuna lecturer of Faculty of Engineering is adviser. From the full period of time 6 years The robot team has the development and build a robot come out many format various the objective such as Transform Robot and Rescue Robot to build come out for use in the competition or A Distributes a Leaflet Robot builds for use in something distribution printed matters of university relations and The Robot seeks and check the material are under suspicion with The Robot Destroy a Bomb with High Pressure Water Gun were designed and establish for help to solve the unrest in nation. However the objective that design and build different but university will receive a reputation in social cooperate from outside both of government sector and privatization sector in intellect and money. In a important get the revelation spreads the fame of Rajamangala University of Technology Phar Nakhon for stand stay the front in first class university of the country and developing new graduate step to the new generation career for the future.

This research aims to develop the guidelines of an automated educational recommending system through various social media in form of chat robots (Chatbot). This is under the assumption that the Chatbot can assist the human workload in responding to Students’ frequently asked questions (FAQ). With the Chatbot inquirer students would be responded in fast and accurate to the inquiries. The prototype of this system is built on the Dialogflow platform to connect to the Line Application. The prototype was tested via users and received “good” level of the overall user’s satisfaction.
