Automated Immersion Testing Robotic System - Hardware and Software Design

Abstract

Hardware and software development of a fully automated robotic work cell to determine the water sorption-diffusion properties of plastics and organic matrix composite materials and to handle all data acquisition is described. Immersion testing involves measuring weight changes of specimens as a function of the time they are immersed in water at a particular temperature. This test method is labor intensive and tedious, involving repetitive operations such as transferring liquids and specimens, blotting and weighing specimens, and recording data. Immersion studies can take years to complete and generate enormous amounts of data which must be recorded and evaluated. Through automation, immersion testing is no longer limited to an 8-hour work schedule, labor costs have been reduced, productivity has been increased tenfold, and the reliability, precision, and accuracy of the test have been improved. Keywords: Materials durability, Environmental tests, Polymers, Diffusion uptake, System verification.
