  10. 10. Selecting Robots for Use in Drug discovery and Testing
  11. 11. ROBOT?
  12. 12. DEFINITION: &quot;A reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks&quot; Robot Institute of America, 1979
  13. 13. Benefits of using Robots in Drug Discovery and Testing <ul><li>Faster, more consistent and more cost-effective </li></ul><ul><li>High degree of repeatability </li></ul><ul><li>Every parameter in </li></ul><ul><li>the process can be automatically monitored, recorded and </li></ul><ul><li>verified </li></ul><ul><li>Thorough documentation is possible </li></ul>
  14. 14. Types of Robots There are three types of industrial robots most commonly used in drug discovery and testing: (1) Cartesian (2) SCARA(selective compliance articulated robot arm) (3) Articulated.
  15. 15. Cartesian Robots
  16. 16. <ul><li>Chief advantage of Cartesian robots </li></ul><ul><li>Low in cost </li></ul><ul><li>Often incorporated into automation subsystems or </li></ul><ul><li>machines dedicated to a single purpose, such as assay testing </li></ul><ul><li>Disadvantage </li></ul><ul><li>although their restricted range of motion limits their usage. </li></ul>
  17. 17. SCARA Robots <ul><li>Selective Compliance Articulated Robot Arm </li></ul><ul><li>The unique design of SCARAs gives them a high degree of rigidity </li></ul><ul><li>moves very fast and with </li></ul><ul><li>precise repeatability </li></ul><ul><li>SCARAs excel at high-speed </li></ul><ul><li>pick-and-place and other material-handling tasks. </li></ul>
  18. 18. Articulated Robots
  19. 19. <ul><li>vertically rotating “forearm” </li></ul><ul><li>and two vertically rotating “wrist” joints, let them </li></ul><ul><li>perform many of the same types of movements as a human </li></ul><ul><li>forearm and wrist </li></ul><ul><li>pick up an object no matter how it is oriented off </li></ul><ul><li>the horizontal plane </li></ul>
