This paper describes the development and operation of an autonomous robotic system designed for pyroprocess automation. The unique challenges of pyroprocess automation, such as the need for a highly dry atmosphere to handle materials like chloride, are addressed through this system. For the experiments, a specialized dehumidifier and dry mock-up facility were designed to produce dry air condition. Performances of dry air conditioning for the various simulated situations were evaluated, including assessing worker access within a mock-up to determine the system’s feasibility. To enable automation, containers used for processing materials were modified to fit the gripper system of the gantry robot. The loading and unloading of materials in each equipment were automated to connect them with the robotic system. This gantry robot primarily utilized macro motions to approach waypoints containing process materials, reducing the need for precise approach motions. Its tapered jaw design allowed it to grip target objects even with imperfect positioning. The robot’s motions were programmed initially using a robot simulator for positioning and motion planning, and real-world accuracy was tested in a dry mock-up facility using the OPC platform. Finally, the paper discusses the potential application of XR (eXtended Reality) technology in this context, which could enhance the robot’s operation and provide valuable insights into the automation process. Further analysis of XR technology’s feasibility and benefits for this specific pyroprocess automation system are presented.

Purpose: To examine the relationship between working in a very dry clean room (relative humidity less than 1%) and dry eye, and its progress by lapse of time. Methods: Targeting 352 employees working in a clean room of onesecondary cell production plant, it performed a dry eye examination in 2011, 2012, and 2013, totally three times. It performed the TFBUT, Schirmer’s test,slit lamp microscope examination, and Mac Morning survey. dry eye stages were classified based on the DEWS criteria. The annual examination results were analyzed through the Anova test and the post-mortem was conducted with Tukey, and in order to learn the effect of working time on dry eye, anunivariate logistic regression analysis was conducted having dry eye examination results as a dependent variable and working time as an independent variable. Results: According to TFBUT and Mac Morning survey, dry eye degenerated as time passed. There was no change in the Schirmer’s test. Considering that as a result of the univariate logistic regression analysis having dry eye examination results as a dependent variable and working time as an independent variable, in the Mac Morning survey, the cross ratio increased up to 1.127(95%CI 1.033~1.230)by lapse of time, it could be found that as working time is elongated, the complaining rate of dry eye increases. Conclusion: It is thought that a clean room with a relative humidity less than 1% affects causing dry eye. Working time limitation, job rotation, and health care such as prescription of artificial tear solution without preserved agent are necessary.
