Real‐time line tracking based on web robot vision

Abstract

This study presents a real-time line tracking application based on web robot vision. The application is implemented with the help of Web-SUN robot platform specially designed for research and development. Real-time images were processed with the support libraries. The processes such as monitoring, tele-control, parameter adjustment, and remote-reprogramming were implemented on the designed platform through standard Internet browser without any additional software. A projection-based line tracking algorithm and conventional PID control algorithm are used in study. Line tracking experiments are performed on a test track drawn by red tape on floor which includes curves and corners in laboratory environment. In this study, our real-time line tracking experiments was completed smoothly in 10 tours on the test track with a maximum deviation of 12 cm.

Design and implementation of a remote laboratory platform using MATLAB builder for NE

“…Recently, several experimental boards with interactive web applications are presented in the literature. The studies are related to subjects such as the design of a remote accessible e‐lab , implementation of a virtual laboratory to speed control of asynchronous motor with PI controller , four‐quadrant control of a DC motor with virtual laboratory , engineering design, analysis, and simulation with MATLAB over Internet , remote control laboratory with MATLAB and Simulink , web‐based laboratory for DC motor experiments , interactive education applications with MATLAB web server , development of an educational Internet interface with MATLAB Builder for NE for digital modulation techniques , synchronous machine application for virtual electrical machines laboratory , USB‐PC data transfer interface with PIC18F4550 microcontroller , synchronous generator experiment with virtual electrical machines laboratory , digital electronic laboratory design for digital input–output application with PIC16C765 microcontroller , Internet‐based energy and power quality observation system , Internet‐based real time line tracking robot application , Internet‐based industrial heating measurement and control system , virtual electrical machines laboratory to detect saturation state application of asynchronous motor , design, application, and evolution of Internet‐based power electronics laboratory , Internet‐based remote control laboratory , several Internet‐based interactive education infrastructures , web‐based virtual laboratories for reinforced concrete education and automatic control teaching with virtual laboratory . All the studies cited above minimized the cost while eliminating risk factors which may occur during conventional laboratory environments due to high voltage applications.…”

“…Furthermore, flexibility and usage of the system with graphical representations are increased in this study since the Matlab Web Figure tool is used, which is not supported by the MWS. Another novelty of this study is to utilize universal serial bus (USB) 2.0 instead of serial or parallel ports, which are widely used in some studies . Thus, the connection speed and the data transmission rate of the system developed are increased to a maximum level (480 Mbit/s).…”

Vision‐based control of a line‐tracing mobile robot

“…In the last decade, the research in the field of mobile robots has been spreading into different areas. Mobile robots are increasingly used in industry , domestic needs (lawn mowers, vacuum cleaners, toys), hazardous environments (firefighting, military applications), and also for educational purposes . The increasing trend of mobile robot applications is expected to continue in future as well.…”

“…This type of robot is used in many applications . By far the most well known are the line‐tracing applications . The robot is typically made of a chassis with wheels and a ball caster.…”

“…The other possibility is a robot mounted camera . Such an architecture is usually referred to as an autonomous guided vehicle (AGV) [8,13]. This approach, due to the inherent image analysis, makes it possible to implement more advanced types of control, such as predictive control.…”
