WhereWhere do you want to automate ? do you want to automate ?

• Location• Access• Floor• Facilities

– Compressed air– Vacuum– Power– IT Network access


WhyWhy do you want to automate ? do you want to automate ?

• Increased throughput• Improved data quality• Plate tracking• Sample identification• Reduced analysis cost• Safety


HowHow do you want to automate ? do you want to automate ?

• partial automation• complete automation• definition of success• data handling• integrator


Golden Rules of AutomationGolden Rules of Automation

If it doesn’t work manually …

… it won’t work more efficiently, if you automate it!

Just because it works manually …

… doesn't mean it will work, if you automate it!


IntegrationIntegration

Automated systems have to be build and integrated • DIY• Single provider• Independent integrator


WhenWhen do you want to automate ? do you want to automate ?

• All at once• Step by step


WhatWhat do you want to automate ? do you want to automate ?

• Small– instrument only connections– no robots– Stacker versus laboratory robot

• Medium– workcells– small static robots

• Large– systems, distributed processing– tracked robots


Choice of equipmentChoice of equipment

Usually• decided by the science• methods have been decided• equipment has been decided• automating a manual method


Choice of automationChoice of automation

• Budget• No of pieces of equipment• Reliability• Safety• Laboratory space


Choice of robot or stackerChoice of robot or stacker

• Types– Stackers– Laboratory robot– Factory robot

• Every integrator has a favourite• Most customers have favourites


StackersStackers

Positives• Commercially available• 1-2 instrument access

Negatives• Poor data handling• 1-2 instrument access

Best system• OVERLORD • Stacker• instrument


Stacker exampleStacker example

• OVERLORD™• RapidPlate• GE LEADseeker• Barcode reader• Data handling• Plate tracking


Laboratory robotsLaboratory robots

Positives• Small• Versatile• Safe

Negatives• reliability

Factory robotsFactory robots

Positives• Accurate• Reliable

Negatives• Needs screening

Small automated systemsSmall automated systems

• Small– instrument only connections– no robots

• Analysis or sample preparation method• Devices to undertake method• System consists of

PCsoftware to control the system


Medium automated systemsMedium automated systems

• Medium– workcells– small static robots– <= 5 instruments

• load and unload operations• plate reader• plate washer• diluter• System consists of

EnclosuresEnclosures

Why do you need ?• Safety• Protect experiment• Key access

Options• Extraction system


Choice of schedulerChoice of scheduler

• pre-emptive• real-time


Scheduling - Pre-emptiveScheduling - Pre-emptive

• Pre-emptive– static– run optimised before equipment moves– simple to set up– not good on error recovery or flexibility


Scheduling - real timeScheduling - real time

• Real-time– flexible– good at error recovery– poor on MULTIPLE key timings

e.g Incubations, Shaking


Automated method designAutomated method design

• Sub divide process into logical steps• Have one global routine• Teach all the robot moves as

– “get …” and “put …”• Combine routines to make sub units

– “load plate reader and run method”


Interfacing to LIMS & data sourcesInterfacing to LIMS & data sources

• LIMS is a mature market• the main problem is data acquisition• most LIMS offer data collection from single instruments• most data sources

– high data throughput– complex robotic systems

• need to offer more comprehensive interface to LIMS

OVERLORD™



How OVERLORD can be used in the How OVERLORD can be used in the Integration LayerIntegration Layer

OVERLORD has• choice of external calling protocols• full file reading ability

– text file/csv– Microsoft Access– SQL

• ability to control most instruments• ability to control most automated workcells


CommunicationCommunication

• Indirect – A CSV file is used to exchange data • Direct – OVERLORD interfaces directly to LIMS

– e.g Use ODBC


Indirect CommunicationIndirect Communication

ADVANTAGES

• All LIMS can communicate using CSV Files

• Easy to integrate

DISADVANTAGES

• Error handling is poor in an Automated System

• Limited Data Exchange


Direct CommunicationDirect Communication

ADVANTAGES

• Integration is more efficient• Access more data• Error Recovery

DISADVANTAGES

• More time needed to set up the integration

• Greater understanding of the LIMS required


Which integration method is best?Which integration method is best?

• Depends on volume of data and type of data

• Use Indirect if….– low data exchange– data is only being ‘pushed’

• Use Direct if….– great level of data exchanged– Automated system runs off the data from LIMS


Documentation of projectsDocumentation of projects

• Why document ?• User Requirement Specification (URS)• Functional Design Specification (FDS)• Factory Acceptance Tests (FATs)• Site Acceptance Tests (SATs)


User Requirement Specification (URS)User Requirement Specification (URS)

• Tell a supplier what you want

• Instrument choices• Full methods• Throughput• Data handling• Aspirations


Functional Design Specification (FDS)Functional Design Specification (FDS)

• Get what you want

• Full details of how URS will be achieved

• Signed agreement point


Factory Acceptance Tests (FATs)Factory Acceptance Tests (FATs)

• See what you want exists

• Demonstration of an agreed set up of tests• Usually down with water

– Sign each test as completed


Site Acceptance Tests (SATs)Site Acceptance Tests (SATs)

• Receive what you want

• Retest some or all of the FDS test• Run with real materials• Sign each test as completed


In summary ...In summary ...

The key points are:• Decide what you want to do very carefully• Plan plan and plan again• Write a detailed URS• Engage a suitable integrator• Follow the project• Stay involved• Be prepared to learn
