Robotic system movement

Robotic system An automated system, usually controlled by a computer, to transfer materials by physical inovcnwnt of a deliver) device or by movement of the reaction ve.ssel.s. Robotic systems cun be general purpo.se. and capable of being repri nimincd to do a variety of dilTcrcnt tasks, or may be specialized, us p in of a tumkes system. [Pg.63]

The starting point for the development of automation concepts was in analytical routine laboratories (e.g. analytical R D and quality control) dealing with high numbers of samples routinely to be analyzed by the application of standardized operation procedures [349]. In parallel, the first robot systems for research were developed and these combine the key technology of liquid handling with the movement of items through a defined space. [Pg.139]

The manipulator constitutes the mechanical system of the robot and Is composed of two essential elements various parts, linked via suitable joints (kinematic pairs), which are responsible for the robot s movements (translation and rotation), and gripping devices which mimic the actions of the human... [Pg.251]

Pure Spot FSW. Sakano et al. (Ref 6) illustrated a newly developed spot FSW robot system for lap joints of aluminum plates. The system was comprised of a specially designed spot FSW gun and a multiarticulate robot. The gun had an FSW probe with rotational and axial movements individually executed by servomotors therefore, the entire welding sequence was controlled by the central processing unit (CPU) of the robot system. Not only did the spot FSW lap joint have equal or superior mechanical properties to the conventional RSW, it also showed significantly lower energy consumption and maintenance cost in comparison with current RSW systems. [Pg.236]

Remember from Chapter 2 that systems can be either open loop or closed loop. Robots are considered a closed-loop system. A robot can respond to changes and adjust its inputs or outputs. Sensors can provide the inputs to the program, or the feedback, that controls the robot s movement or actions. [Pg.352]

Maziarz et al. [67] analyzed a siloxane PDMS terminated with HB (4-hydroxybutyl) on both sides. A commercial LabConnection was used with an automated interface for SEC sample collection and subsequent preparation of samples for MALDI analysis. Figure 45.13 contains the SEC trace and MALDI spectra of eight fractions, respectively. The fractions are centered at 1.1,1.3,1.7,2.0,2.6,3.0,3.9, and 5.0 kDa, respectively. The authors used Equations 45.3 and 45.4, to compute molar mass averages (step SMI). The result was Mn = 2012 Da and My, = 1578 Da. The authors also performed the operations described in step (SM2). The percent difference was relevant. In another study that involved a sample in which two different types of PDMS chains were present [68], the authors did not use the LabConnection automated interface or similar interfaces. Fractions were collected manually. In fact, some of these interfaces require an expensive robotic system with precise XYZ movements and some do not allow for variations in the matrix analyte ratio to optimize the MALDI spectral resolution of the higher molar mass fraetions, which need a matrix analyte ratio very different from that of lower MM fractions. [Pg.1094]

In the second category we can find back-drivable serial arms that can be manually positioned by surgeons. Transparency, which quantifies the ability of a robot to follow human movements without requiring any human-perceptible resistive force drive, is one of the major issues in the field of human-robot interaction for assistance in manipulation tasks [23]. Cooperatively controlled robotic systems are used in robotic surgery, e.g., the... [Pg.11]

Mobile Robot System robot that contains what is needed for its movement and displacement (power, control, and navigation system). [Pg.106]

Point-to-pointtrackingteehnique is implemented in the proposed mobile robot system. Assuming that a desired route described as xjt) and yjt), to the coordinate axis x and y, is obtained from a movement planning system. For instance, it is desirable that the mobile robotmove inasinusoidal route, for example yjt) = 5sen(t), while in the space x/t) = 4t-5, which describes a linear route. [Pg.152]

Before any physical movement is done in the real inspection environment, the optimal robot configuration and motion are planned and simulated in a virtual iuspection environment in the ROBCAD 3D robot simulation system. If any collisions or near-collisions are occurring or all the calculated inspection points can not be reached the robot configuration and/or robot inspection programs can be adjusted off-line accordingly without the need of the physical robot or inspection environment. This ensures that the time scheduled for the physical inspection is used actively for inspection instead of testing and configuration. [Pg.871]

Early laboratory robots were unreliable, but today, these systems perform quite well. Today s robots simply move plates from one robot-friendly position to another, such as the entrance pad of a plate reader. These simplified movements combined with the low weight of a plate allow engineering to simplify the robot designs. As seen in industrial application of robots, robots that are defined and used for a specific application will work day in and day out quite well. It is always best to keep the automation as simple as possible to get the highest level of performance. This is usually accomplished by minimizing the number of moveable parts associated with the automation. Stackers have also become more reliable. This was due, in part, to the standardization of the microplate by an effort of the Society for Biomolecular Screening (Danbury, CT, U.S.A.) in association with the American National Standards Institute (ANSI, Washington, DC, U.S.A.), but also due to the use of simpler stacker mechanisms. Today, there are many choices for devices, workstations, and fully automated systems. The selection as to which automated devices to purchase for HTS should be driven by a clear set of specifications that define the use of the automation. The choices can be expensive, and therefore, replacement may not be possible, so it is important to choose well. [Pg.83]

Health and safety requirements Mechanical safety for robotic movement, radiation safety for systems that involve the use of radioactive sources, and laser safety for systems that use high-power lasers. [Pg.796]
