Development of a demonstration set of object sorting robotic arm and automatic production control with the programmable logic controller

Abstract

          The objectives of this research were to 1) develop and evaluate the quality of the object sorting robotic arm and automatic production control using a programmable logic controller, 2) determine the efficiency of the object sorting robotic arm and automatic production control using a programmable logic controller; and 3) compare the learning achievements before and after the class.A sample group in this research was from 30 third-year undergraduate students of Mechanical Engineering enrolled in the Hydraulics and Applied Pneumatics course in semester 1 of the academic year 2022 at the Faculty of Industrial Education, Rajamangala University of Technology Phra Nakhon. The sample was derived from the simple random sampling method in the classroom. The research instruments included the mobile hydraulics training set, a test used during class and after class, and the quality assessment sheet for the training set. Data were analyzed statistically by mean, standard deviation, and dependent samples t-test. The research results showed as follows: 1) The average result of the assessment of the quality of the training kits by the experts in the design and structure quality field was in good level, with average and standard deviation (=4.18, S.D.=0.53). The average result of functional quality was at very good level (=4.62, S.D.=0.32) while the average result of the quality assessment for the experimental sheet was evaluated at good level (=4.40, S.D.=0.43). 2) The efficiencies of the training sets and experimental worksheets when applied to the learners were 82.21/86.10, which followed the threshold set at 80/80. Finally, 3) Students had a statistically significantly higher level of academic achievement after the class than before the class .01 level accordingly to the hypothesis.
