A remote laboratory for robotics accuracy and reliability studies

Abstract

Accuracy and reliability studies for remote laboratories are utilized in a wide range of curricula in both engineering and engineering technology programs. In a typical undergraduate class, learning of a theoretical method is often reinforced by analysis and practical experiments. Using a remote measurement technology, theoretical learning is complemented by online experimental verifications. The paper addresses the development of a remotely controlled laboratory setup that allows monitoring the resulting reliability and accuracy. The setup incorporates modern sensors, data acquisition instrumentation, and programs to monitor and control such an application. These tools are beneficial for laboratory practices in undergraduate level quality control or instrumentation classes. The entire process shows results based on the data that is collected in real-time through the Internet. The system demonstrates the effectiveness of an online calibration tool to test for position accuracy and repeatability of a robotic device. The results provide students with a "hands-on" approach to learning, allowing them to thoroughly understand the measurement research process. © 2011 American Society for Engineering Education.
