Blood tests are one of the core processes in the clinical laboratory test field. In hospitals, an automated process called total laboratory automation (TLA), which relies on a set of sophisticated equipment, is normally adopted for the tests. Noting that the TLA system typically has a large footprint and requires a significant amount of power, slim, and easy-to-move blood test equipment is necessary for some specific demands such as emergency rooms or small-size local clinics. Although various portable blood test systems are introduced and popularly used in many labs, the test processes of these systems are not usually flexible. In the present work, a new scheduling algorithm called reduced idle time (RIT) is developed for a small-scale portable Bio Robot platform. The RIT can successfully handle a series of components of the Bio Robot such as a liquid handler, six incubators, a newly developed spectrophotometer, and a robot arm. It also shows an enhanced effectiveness in terms of the testing time reduction when it is tested with the developed robot platform. Additionally, the RIT shows a fairly flexible capability to accommodate new incoming samples that might interrupt an on-going process and requires an immediate rescheduling. © 2010 The Association for Laboratory Automation.

Most safety inspections of large piping structures are performed by humans. However, this approach requires considerable time and money and does not guarantee the safety of the inspectors. The proposed pipe-climbing robot is designed to move on the outside of large pipe structures and perform non-destructive inspection in place of human inspectors. Required to negotiate external obstacles such as fixtures, flanges, and valves, as well as pipe components such as elbow and T-branch joints, the proposed pipe-climbing robot comprises two driving modules and an actuated connecting arm. By working together, the two driving modules overcome the various obstacle components in a pipeline network. The wheel-driven locomotion mechanisms of the system also enable it to move quickly along the pipeline. A strain gauge is attached to the climbing arm to confirm the grasping state of the robot on the pipe. The robot is designed to attach stably to a pipe, which features a very low backlash, by means of worm drive and ball screw mechanisms. Experiments show the ability of the robot to grasp stably on a pipeline and climb the pipeline at a speed of 18 cm/s. © 2016, The Korean Society of Mechanical Engineers and Springer-Verlag Berlin Heidelberg.

Blood tests are some of the core clinical laboratory tests for diagnosing patients. In hospitals, an automated process called total laboratory automation, which relies on a set of sophisticated equipment, is normally adopted for blood tests. Noting that the total laboratory automation system typically requires a large footprint and significant amount of power, slim and easy-to-move blood test equipment is necessary for specific demands such as emergency departments or small-size local clinics. In this article, we present a point-of-care test system that can provide flexibility and portability with low cost. First, the system components, including a reagent tray, dispensing module, microfluidic disk rotor, and photometry scanner, and their functions are explained. Then, a scheduler algorithm to provide a point-of-care test platform with an efficient test schedule to reduce test time is introduced. Finally, the results of diagnostic tests are presented to evaluate the system. © 2014 Society for Laboratory Automation and Screening.
