Introduction<br />

by Laurence Painell<br />

<strong>Lab</strong>oratories are constantly evolving. Systems, processes,<br />

machines, techniques, and layouts are always changing and<br />

adapting to the science and innovation required to design,<br />

test, and bring to market new products—and automation has<br />

a huge role to play.<br />

<strong>Automation</strong> and other developments like machine learning<br />

and robotics are already making waves in the industry by<br />

relieving researchers of mundane tasks and increasing<br />

accuracy and efficiency. Just look at high-throughput labs,<br />

where automation and robotics have been commonplace<br />

for decades. Thanks to modern technologies and the<br />

bidirectional nature of communication, the door is slowly<br />

being opened to more opportunities and innovations that<br />

could reduce time to market further while addressing<br />

other important issues such as regulatory compliance and<br />

transparency.<br />

The <strong>Lab</strong> of Tomorrow<br />

What might the lab of the future look like?<br />

Where will automation fit in? Here are some predictions.<br />

by Laurence Painell<br />

The next five years<br />

Despite the speed of technological advancements,<br />

introducing new systems and processes in a laboratory<br />

can take time. Over the next five years, it might not look<br />

as though labs are changing significantly—but if you look<br />

beneath the surface, some major developments are likely to<br />

be taking place.<br />

• The cloud will become the norm even in regulated<br />

environments<br />

• Integration between software, services, and physical<br />

devices will be critical to providing a backbone for<br />

laboratory technologies<br />

• Collaboration and outsourcing will become<br />

commonplace<br />

• Data will become increasingly open and available across<br />

a given lab or business<br />

• The keyboard will be replaced with voice recognition<br />

technology<br />

• As the technology matures, 3-D printing will work its<br />

way further into prototyping and manufacturing<br />

EXPERT TIP:<br />

THE SECRET TO<br />

AUTOMATION SUCCESS<br />

“I think the secret to automation success is two-fold. First,<br />

know your extraction method really well and think about<br />

how you would perform it from a robot’s perspective.<br />

The method has to be automatable and no robot will be<br />

as perceptive or responsive to variations in the process as<br />

a human operator. Second, be the master of your robot.<br />

Vendor companies will provide programming support, but<br />

to guarantee success you need at least one staff member<br />

who is capable of programming the instrument. Vendors<br />

may be experts at programming, but they are unlikely to<br />

know your process as intimately as you do.”<br />

Research Unit at Racing Analytical Services, Ltd.<br />

• AI and machine learning will becoming more prevalent<br />

• <strong>Lab</strong>s and businesses could decide to unlock their legacy<br />

data for the greater good<br />

• The internet of things (IoT) will create a steep<br />

change in efficiency by allowing for bidirectional<br />

communication between instruments, robots, and the<br />

systems and services used<br />

• It will be interesting to see how augmented reality<br />

develops over the next decade—but it’s something<br />

we could see slowly integrated into the laboratory<br />

environment<br />

The next 10 years<br />

This is where we start to break from certainty and start to<br />

look at changes that we expect to see based on the current<br />

evolution of technologies.<br />

• Radio-frequency identification RFID tags that allow the<br />

automatic reading of data will become cheap enough to<br />

be ubiquitous<br />

A Scripting Approach to <strong>Automation</strong><br />

Many laboratories still have not adopted automation, mostly due to the high cost of standard<br />

automated laboratory instruments. The situation is aggravated by the lack of compatibility<br />

between instruments made by different manufacturers.<br />

by Matheus C. Carvalho<br />

The problem of lack of compatibility between<br />

laboratory instruments has been recognized since the<br />

1990s. It has prompted some groups of laboratory<br />

professionals (see, for example, the Standardization in<br />

<strong>Lab</strong> <strong>Automation</strong> and Clinical and <strong>Lab</strong>oratory Standards<br />

Institute initiatives) to propose the standardization of<br />

laboratory instruments. The reason is that standardized<br />

instruments would be compatible with each other. However,<br />

standardization involves considerable costs for instrument<br />

manufacturers and end-users, and thus standardization<br />

has achieved only limited success to improve instrument<br />

compatibility, a situation that will probably not change in the<br />

next few years.<br />

Fortunately, it is not necessary to wait for standardization<br />

in order to cope with the lack of compatibility between<br />

instruments. It is possible, today, to buy an instrument from<br />

company A and combine it with another from company B.<br />

And you do not need to be a technical wiz to do it—all you<br />

need is to learn about scripting.<br />

The scripting approach<br />

The technology that enables unrestricted compatibility<br />

between laboratory instruments is scripting, a<br />

variation of computer programming. Among scripting<br />

languages, AutoIt stands out as probably the most useful<br />

for integrating laboratory instruments because it enables<br />

automation of mouse clicks and keyboard entries. AutoIt has<br />

been developed and perfected since 1999, and it is entirely<br />

free.<br />

The main difference between the traditional approach for<br />

instrument integration and the one based on scripting is<br />

the way information is exchanged between instruments.<br />

In the traditional way, instruments send signals to each<br />

other (Figure 1). With scripting, instruments do not send<br />

signals to each other at all; instead, a computer (or more<br />

than one computer in a network) controls all instruments<br />

(Figure 2), and sends commands to them in an orderly<br />

fashion. Therefore, it is not necessary that the manufacturer<br />

of a certain instrument design this instrument with<br />

capabilities to communicate with other instruments: the<br />

only thing that is necessary is that the instrument can be<br />

controlled by a computer, which is a default capability in<br />

almost all instruments nowadays. Therefore, nothing extra<br />

is needed from the manufacturer’s side (compare this to<br />

standardization, which could demand a complete overhaul<br />

of the production process).<br />

Also, scripting is very accessible for the user. No knowledge<br />

of electronics or low-level computing is necessary. In fact,<br />

scripting is probably the easiest kind of programming that<br />

exists. Controlling different instruments using the AutoIt<br />

scripting language can be very simple; for example, the<br />

instruction “MouseClick,” which, as the name implies,<br />

executes a mouse click. Another instruction, “Send,” sends<br />

keyboard entries. These instructions can be called at spaced<br />

intervals (determined by the instruction “Sleep”) and at<br />

different coordinates on the computer screen. Therefore,<br />

the synchronization of two or more graphical interfaces,<br />

each controlling a different instrument, can be easily and<br />

intuitively enabled. This means that laboratory technicians<br />

and scientists can develop solutions for their instrument<br />

compatibility problems without the need for advanced<br />

technical support.<br />

More sophisticated control is also possible with AutoIt.<br />

For example, signals on the screen, like a popup window<br />

displaying “Waiting” or a button that is normally green<br />

but becomes red if a certain condition arises, can be<br />

incorporated into the coding, thus enabling interactive<br />

scripting. In addition to that, control of interfaces without<br />

direct use of the mouse and/or keyboard is also possible,<br />

thereby freeing the computer for multitasking. Finally,<br />

even remote synchronization is possible through the<br />

Internet. These and other more advanced solutions can be<br />

implemented after a deeper study of AutoIt.<br />

The following are examples of applications that can benefit<br />

from a scripting approach:<br />

• Use of low-cost, easy-to-program robotic arms as<br />

autosamplers<br />

• Extending the life of older equipment by adapting the<br />

sampling mechanism of one device to a different one<br />

• Simplifying integration of accessories by using Autolt<br />

• Enabling automation for nonautomated devices<br />

LINDA Says...<br />

Companies and core labs are increasingly focused on ergonomics because repetitive stress and strain<br />

from certain manual tasks, such as pipetting, can take a toll on employee productivity and well-being.<br />

<strong>Automation</strong> takes over those more mundane tasks to eliminate the risk of repetitive injuries.<br />

Insights into<br />

Automating Your…<br />

by Mike May, Angelo DePalma, and Joe Liscouski<br />

Biobaking<br />

Some forms of lab work might seem more suited to<br />

automation than others. Biobanking—collecting and storing<br />

samples for research and clinical applications—sounds<br />

like a natural for automation. Applying automation to<br />

biobanking enables control over the whole process around<br />

the sample. For example, controlling the temperature<br />

improves a sample’s quality. Manual biobanking subjects<br />

a sample to greater temperature variation as a freezer gets<br />

opened and closed, and even left open longer than necessary,<br />

which can lead to tens of degrees of temperature changes.<br />

By automating this process, many steps can be completed<br />

without opening the freezer, which can produce temperature<br />

stability to within single degrees.<br />

Also, automation adds an audit trail to a sample, so<br />

researchers can be confident in the products they are<br />

getting out of the biobank. This can be especially useful<br />

in any regulated industry, such as biobanking samples for<br />

pharmaceutical research.<br />

When thinking about automating a biobank, though,<br />

researchers need to think ahead. One should choose an<br />

adaptable solution to meet future needs. For example,<br />

standardizing tube formats for automating tube storage and<br />

retrieval, such as using 2-D bar codes, enables researchers<br />

to track and cherry-pick samples that have been stored<br />

previously.<br />

Liquid Handling<br />

Systems exist for nearly every lab, workflow, and throughput<br />

level, even for many labs that believe automation is too<br />

complex or too expensive. All automated systems share one<br />

characteristic: They all replace tedious manual operations,<br />

which is where most errors occur.<br />

Full-blown robotic liquid handling systems are formidable,<br />

integrated systems with steep learning curves, but complexity<br />

is somewhat mitigated through improved interfaces. At the<br />

mid-range level of complexity, vendors are taking advantage<br />

of their entry- or mid-level automation products to create<br />

application-specific systems that may be reconfigured<br />

down the road as workflow demands change. This product<br />

development strategy requires balancing immediate needs<br />

with future-focused flexibility.<br />

<strong>Lab</strong> managers typically believe that if manual pipettes are not<br />

enough, they have to splurge on a robotic system. However,<br />

they should consider options in between, which may be more<br />

economical and, for many workflows, more efficient. Semiautomated<br />

systems, for instance, are simpler than robotics and<br />

spare end users from extensive training<br />

It all comes down to understanding workflows, and whether<br />

one wants to ramp up a little or a lot. Without full automation,<br />

a ninety-six-channel pipette still improves throughput<br />

significantly compared with a conventional handheld pipette.<br />

Managers need also to consider how many people will be<br />

using the instrument. If it’s a dedicated system, with a single<br />

task, with preprogrammed methods, and if walkaway time is<br />

valued, then a robotic system is appropriate.<br />

competitive advantage, consider having a partnership with<br />

companies with similar needs to jointly develop automated<br />

solutions. This should reduce the cost of development and<br />

provide a more robust system with better support. It may<br />

also provide enough market justification for an equipment<br />

vendor to step in and develop hardware to fit the application.<br />

Sample Preparation<br />

Sample preparation can be a labor-intensive and<br />

expensive process. Unless the process is specifically designed<br />

for automated implementation, the process is going to have<br />

to be analyzed to see what it will take to make it suitable<br />

for semi-automated or fully automated work. The first item<br />

that has to be determined is whether you are using the<br />

current, up-to-date description of the process, including any<br />

undocumented workarounds or temporary fixes.<br />

Next, one must evaluate whether there is anything about<br />

the process that precludes automation. This would include<br />

working with objects or materials that depend on human<br />

dexterity and might not be usable with robotic systems. If<br />

that is the case, is it possible to modify the equipment or<br />

process to make the automation work without altering the<br />

science itself ? Another consideration is whether the process<br />

can be optimized—this may be necessary in order to meet<br />

performance goals.<br />

Early robotic sample preparation system implementations<br />

mimicked human activities, carrying out the same steps,<br />

one at a time, that people did. This removed people from<br />

the system (one goal) but often didn’t process more samples<br />

per hour, although it did provide a means for three-shift<br />

operation. Process optimization may require a change in how<br />

the process takes place, as long as it doesn’t compromise the<br />

integrity of the results.<br />

Sample preparation methods that are based on standardized<br />

sample containers will reduce the effort in automating<br />

systems. This is particularly true of autosamplers that use<br />

standardized vials. The use of standardized components<br />

reduces development costs, increases the likelihood of<br />

success, and permits reconfiguration of systems as needs<br />

change.<br />

Immunoassays<br />

Enzyme-linked immunosorbent assays (ELISAs) detect and<br />

quantify a target protein in a sample, and are used in many<br />

industries. This technique, however, involves incubation<br />

and washing steps, which make it complicated to run lots of<br />

these assays at the same time.<br />

The multiple steps and their required precision in ELISAs<br />

make these assays worth automating. Using microplate<br />

handlers and automation in general, especially in<br />

combination with scheduling software, will help to ensure<br />

the correct and similar timing of all plates when running<br />

several plates in a batch. This provides several benefits<br />

over manual processes, such as higher throughput, better<br />

precision, and reduced labor hours.<br />

Despite such alluring benefits, some challenges exist. If the<br />

vendor stops supporting a microplate handler, a user will<br />

eventually need to replace it and revise the automated assays<br />

as needed. Older microplate handlers can also cause trouble<br />

when they don’t integrate with newer equipment being used<br />

in the assay.<br />

In considering a purchase, labs should look for what fills<br />

all of their needs. It is not practical, for instance to provide<br />

extensive training for all end users, but the right interfaces<br />

can provide a layer of separation between users and the<br />

automation systems.<br />

If your application requires a custom-designed solution<br />

based on individual components (robotic arm, sample<br />

holders, etc.), the cost of development can increase<br />

significantly. Unless you believe that having a particular<br />

automated sample preparation system provides a<br />

Return on Investment<br />

Consider both sides of the equation when calculating your ROI.<br />

by Joe Liscouski<br />

The goals of lab automation include:<br />

• Overall cost reduction, including labor and materials<br />

• Greater consistency<br />

• Higher productivity<br />

• More extensive analyses<br />

• The potential for 24/7 operations<br />

EXPERT TIP:<br />

MINIMIZING COST OVERRUNS<br />

“A lot of times, robotics is sold on the concept of<br />

versatility, but reliability then becomes the Achilles’<br />

heel. Then you run into cost overruns, having to repeat<br />

experiments and analyses. One way to minimize cost<br />

overruns is to minimize human or manual interactions<br />

that can lead to errors that are propagated down the<br />

pipeline. So in your design, you must have instruments<br />

and protocols undergo quality control so as to not amplify<br />

mistakes during high-throughput screening.”<br />

Louis Scampavia, PhD, co-director of the High-<br />

Throughput Screening Lead Identification Division at<br />

The Scripps Research Institute in Florida<br />

For any ROI equation, there are two sides to consider. The<br />

first is what you want out of it, which includes some or all of<br />

the points above plus metrics—what level of performance<br />

are you looking for, what are you willing to spend, and what<br />

is the schedule requirement for implementation? You also<br />

have to evaluate the alternatives to automated systems,<br />

which include increasing head count or outsourcing work<br />

for comparison. Those last points would have to include an<br />

understanding of whether the need is a temporary spike in<br />

testing throughput or a long-term requirement; it is going<br />

to take time to implement a solution, and you don’t want it<br />

coming online as the need evaporates.<br />

The other side of the equation covers the costs. They<br />

include the development of the user and system<br />

requirements, a feasibility study, and prototype<br />

work, followed by the actual design, implementation,<br />

documentation, testing, validation, and user education.<br />

Given a set of requirements, the next major step is the<br />

feasibility study—this is going to provide the basis for the<br />

go/no-go decision on the project and guide the design effort.<br />

The Human Side<br />

Making the most of your staff.<br />

by Erica Tennenhouse<br />

Reduction in labor is an unavoidable consequence of lab<br />

automation. That’s because the greatest cost of running<br />

a project is typically associated with staffing. If it takes<br />

fewer people to get the job done, then that becomes a<br />

straightforward measure of ROI. But reduction in labor does<br />

not always mean job loss.<br />

Prior to automation, labs can begin developing other<br />

businesses to launch in conjunction with the automation<br />

going live. This strategy enables labs to repurpose trained<br />

staff members who are already familiar with the lab’s<br />

services and culture for positions in new or growing<br />

businesses.<br />

EXPERT TIP:<br />

WHICH TASKS TO<br />

AUTOMATE?<br />

“It’s important to try to not automate things that humans<br />

are typically good at. For instance, in some labs you see<br />

a lot of sophisticated equipment with long articulated<br />

robotic arms for picking tubes and plates or for moving<br />

stacks in and out of the refrigerator or freezer. People can<br />

do those tasks cheaply and efficiently, and accuracy can<br />

always be checked if the vials and plates are barcoded.<br />

I personally do not think it’s worth spending enormous<br />

amounts of money on robotics for freezer management<br />

and such, unless you are working with a million samples a<br />

year. People think that they have to automate every single<br />

part of a protocol, but they should really be thinking<br />

about automating only those parts that are very routine<br />

and prone to errors.”<br />

Harold Swerdlow, PhD, vice president of sequencing<br />

at the New York Genome Center<br />

When automation opens up new and more challenging roles,<br />

it is often a boon to both the business and the staff. Using<br />

smaller, user-friendly systems to automate routine, tedious<br />

tasks can not only enhance reproducibility and eliminate<br />

user error, but it can also boost morale and productivity by<br />

freeing up scientists to do science rather than mindless tasks<br />

better suited to robots.<br />
