Interview with Andrea Thomaz (co-founder of Diligent Robotics): socially clever automation options for hospitals

By Sonia Roberts, with further enhancing by Dharini Dutia

Diligent Robotics, based by Andrea Thomaz and Vivian Chu, develops socially clever automation options for hospitals. Moxi, their flagship robotic, delivers gadgets like drugs and wound dressings between departments to save lots of the scientific workers’s time. Diligent has simply closed their Sequence B funding spherical with $30 million. 

We sat down with Dr. Thomaz to speak about Moxi, tips on how to handle individuals’s expectations about robots, and recommendation for younger individuals and ladies in robotics. This interview has been calmly edited for readability. 

What sorts of issues are you attempting to resolve with Moxi?

We’re constructing Moxi to assist hospitals with the large workforce scarcity that they’re seeing now greater than ever. We truly began the corporate with the identical intention a number of years in the past earlier than there was a worldwide pandemic, and it actually has simply gotten to be a good greater drawback for hospitals. I really feel actually strongly that robots have a spot to play in teamwork environments, and hospitals are a fantastic instance of that. There’s nobody particular person’s job in a hospital that you’d truly wish to give over to automation or robots, however there are tiny little bits of lots of people’s jobs which are completely capable of be automated and that we may give over to supply robots specifically like Moxi. [The main problem we’re trying to solve with Moxi is] level to level supply, the place we’re fetching and gathering issues and taking them from one space of the hospital to a different. 

Hospitals have lots of stuff that’s shifting round daily. Each particular person within the hospital goes to have sure drugs that should be delivered to them, sure lab samples that should be taken and delivered to the central lab, sure provides that want to come back as much as them, meals and vitamin daily. You may have lots of stuff that’s coming and going between affected person items and all these totally different help departments. 

Each one among these help departments has a course of in place for getting the stuff moved round, however it doesn’t matter what, there’s stuff that occurs each single day that requires ad-hoc [deliveries] to occur between all of those departments and totally different nursing items. So typically that’s going to be a nurse that simply must get one thing for his or her affected person they usually need that to occur as quickly as potential. They’re attempting to discharge their affected person, they want a selected wound dressing equipment, they’re going to run down and get it as a result of they wish to assist their affected person get out. Or if there’s one thing that must be hand carried as a result of the common rounding of medicines has already occurred, lots of occasions you’ll have a pharmacy technician cease what they’re doing and go and run some infusion meds for a most cancers affected person, for instance. It type of falls between these departments. There’s totally different individuals that may be concerned however lots of occasions it does fall on the nursing items themselves. A nurse defined to us one time that nurses are the final line of protection in affected person care.

What’s altering with this most up-to-date spherical of funding?

During the last 6-12 months, the demand has actually skyrocketed such that we’re barely maintaining with the demand for individuals desirous to implement robots of their hospitals. That’s the rationale why we’re elevating this spherical of funding, increasing the workforce, and increasing our potential to capitalize on that demand. A few years in the past, if we have been working with a hospital it was as a result of they’d some particular funds put aside for innovation or they’d a CTO or a CIO that had a background in robotics, nevertheless it definitely wasn’t the very first thing that each hospital CIO was occupied with. Now that has utterly modified. We’re getting chilly outreach on our web site from CIOs of hospitals saying “I must develop a robotic technique for our hospital and I wish to study your answer.” By means of the pandemic, I believe everybody has seen that the workforce scarcity in hospitals is just getting worse within the close to time period. Everyone desires to plan for the long run and do every thing they’ll to take small duties off of the plates of their scientific groups. It’s been actually thrilling to be a part of that market change and see that shift to the place everyone is basically actually open to automation. Earlier than we needed to say “No no no, this isn’t the long run, I promise it’s not scifi, I promise these actually work.” Now [the climate has] actually shifted to individuals understanding “That is truly one thing that may impression my groups.”

[Two of our investors are hospitals, and] that’s been one among our most fun elements of this spherical. It’s all the time nice to have a profitable funding spherical, however to have strategic companions like Cedars-Sinai and Shannon Healthcare coming in and saying “Yeah, we truly wish to construct this alongside you” — it’s fairly thrilling to have clients like that. 

What sorts of technical issues did you run into whenever you have been both constructing Moxi or deploying it in a hospital surroundings? How did you resolve these issues? 

One which was nearly stunning in how typically it got here up, and actually impacted our potential [to run Moxi in the hospital environment] as a result of now we have a software-based robotic answer that’s connecting at a daily foundation to cloud companies, [was that] we had no clue how horrible hospital WiFi was going to be. We truly spent fairly some time constructing in backup techniques to have the ability to use WiFi, backup to LTE if now we have to, however be sensible about that so we’re not spending a complete bunch of cash on LTE knowledge. That was an issue that appeared very particular to hospitals specifically.

One other one was safety and compliance. We simply didn’t know what a few of the totally different necessities have been for hospitals till we truly obtained into the environments and began interacting with clients and understanding what they needed to make use of Moxi for. After we have been first doing analysis trials in 2018 or 2019, we had a model of the robotic that was a little bit bit totally different than the one now we have in the present day. It had numerous open containers so you can simply put no matter you needed to on the robotic and ship it over to a different location. We shortly discovered that that restricted what the robotic was allowed to hold, as a result of a lot of what [the customers] needed was to know who pulled one thing out of the robotic. So now now we have an RF badge reader on the robotic that’s linked to locking storage containers which are solely going to open should you’re the sort of particular person that’s allowed to open the robotic. That was an fascinating technical problem that we didn’t learn about till after we obtained on the market. 

How did you’re employed with nurses and the opposite healthcare professionals you have been working with to determine what could be essentially the most useful robotic for them? 

My background, and my co-founder Vivian Chu’s background, is in human-robot interplay so we knew that we didn’t know sufficient about nursing or the hospital surroundings. We spent the primary 9 months of the corporate in 2018 constructing out our analysis prototype. It seemed loads like what Moxi seems like in the present day. Beneath the hood it was utterly totally different than what now we have in the present day by way of the reliability and robustness of the {hardware} and software program, nevertheless it was sufficient to get that platform out and have it deployed with nursing items. We embedded ourselves with 4 totally different nursing items throughout Texas over a year-long interval. We might spend about 6-8 weeks with a nursing division, and we have been simply there — engineers, product individuals, and everyone within the firm was biking out and in every week or two at a time. 

We might ask these nurses: “What would you truly desire a robotic like this to do?” A part of this that was actually necessary was they didn’t have good concepts about what they might need the robotic to do till they noticed the robotic. It was a really participatory design, the place they needed to see and get a way for the robotic earlier than they might have good concepts of what they might need the robotic to do. Then we might take these concepts [to the company] and are available again and say “Sure we will try this,” or “No we will’t try this.” We got here out of that entire course of with a extremely nice concept. We wish to say that’s the place we discovered our product market match — that’s the place we actually understood that what was going to be Most worthy for the robotic to do was connecting the nursing items to those different departments. We may also help a nurse with provide administration and getting issues from place to position inside their division, or we may also help them with issues which are coming from actually far-off. [The second one] was truly impacting their time approach far more.

As a result of the capabilities of robotic techniques are normally misinterpreted, it may be actually onerous to handle the connection with stakeholders and clients and set acceptable expectations. How did you handle that relationship?

We do lots of demonstrations, however nonetheless with nearly each single implementation you get questions on some robotic in Hollywood, [and you have to say] “No, that’s the flicks” and clarify precisely what Moxi does. 

From a design perspective, we additionally restrict the English phrases that come out of Moxi’s mouth simply because we don’t wish to talk a extremely excessive stage of intelligence. There are many canned phrases and interactions on the iPad as a substitute of by way of voice, and lots of occasions the robotic will simply make meeps and beeps and flash lights and issues like that. 

Earlier than beginning the corporate, I had a lab, and one of many huge analysis subjects that we had for numerous years was embodied dialogue — how robots may have an actual dialog with individuals. I had an excellent appreciation for a way onerous that drawback is, and likewise for simply how a lot individuals need it. Folks come as much as a robotic, they usually need it to have the ability to discuss to them. How one can [set expectations] with the design and habits of the robotic has been a spotlight of mine since earlier than we began the corporate. We purposefully don’t make the robotic look very human-like as a result of we don’t need there to be android human-level expectations, however [the robot does have a face and eyes so it can] talk “I’m that factor” and “I’m about to control that factor,” which we expect is necessary. It’s actually about placing that stability. 

What would you say is one lesson that you simply’ve discovered out of your work at Diligent to date and the way are you trying to apply this lesson shifting ahead?

The distinction between analysis and follow. On the one hand, the motivation and motive for beginning an organization is that you simply wish to see the sorts of issues that you simply’ve performed within the analysis lab actually make it out into the world and begin to impression actual individuals and their work. That’s been one of the vital fascinating, impactful, and provoking issues about beginning Diligent: Having the ability to go and see nurses when Moxi is doing work for them. They’re so grateful! If you happen to simply dangle again and watch Moxi come and do a supply, nearly all the time individuals are tremendous excited to see the robotic. They get their supply they usually’re like, “Oh, thanks Moxi!” That seems like we’re actually making a distinction in a approach that you simply simply don’t get with simply analysis contributions that don’t make all of it the way in which out into the world. 

That being mentioned although, there’s a lengthy tail of issues that it’s a must to resolve from an engineering perspective past [developing a feature]. My VP of engineering Starr Corbin has this smart way of placing it: The analysis workforce will get a sure factor on the product to be function full, the place we’ve demonstrated that this function works and it’s an excellent answer, however then there’s this entire part that has to occur after that to get the function to be manufacturing prepared. I’d say my greatest lesson might be every thing that it takes, and the whole workforce of individuals it takes, to get one thing from being function full to manufacturing prepared. I’ve a deep appreciation for that. How briskly we will transfer issues out into the world is basically dictated by a few of that. 

What recommendation would you give younger girls in robotics? 

If I put my professor hat on, I all the time had recommendation that I appreciated to present girls in robotics, in academia, and simply sort of pursuing issues typically. Imposter syndrome is actual, and everyone feels it. All you are able to do to fight it isn’t underestimate your self. Communicate up and know that you simply deserve a seat on the desk. It’s all about onerous work, but in addition ensuring that your voice is heard. A few of the mentorship that I gave to lots of my girls grad college students once I was a professor was round talking engagements, talking types, and communication. It may be actually uncomfortable whenever you’re the one something within the room to face up and really feel such as you need to be the one talking, and so the extra that you simply follow doing that, the extra snug it will probably really feel, the extra assured you’ll really feel in your self and your voice. I believe discovering that assured voice is a extremely necessary ability that it’s a must to develop early on in your profession. 

What’s one piece of recommendation you’ve obtained that you simply all the time flip to when issues are robust? 

There are two mentors that I’ve had who’re girls in AI and robotics. [In my] first 12 months as a school member [the first mentor] got here and gave a analysis seminar discuss. I for some motive obtained to take her out to lunch on my own, so we had this wonderful one-on-one. We talked a little bit bit about her discuss, in all probability half of the lunch we talked about technical issues, after which she simply sort of turned the dialog [around] and mentioned “Andrea, don’t overlook to have a household.” Like, don’t overlook to give attention to that a part of your life — it’s a very powerful factor. She obtained on a soapbox and mentioned “It’s a must to have a piece life stability it’s so necessary. Don’t overlook to give attention to constructing a household for your self, no matter that appears like.” That actually caught with me, particularly as [when you’re] early in your profession you’re nervous about nothing however success. It was actually highly effective to have someone robust and influential like that telling you “No, no, that is necessary and it’s worthwhile to give attention to this.” 

The opposite person who’s all the time been an inspiration and mentor for me that I’ll spotlight [was the professor teaching a class I TA’d for at MIT]. I had discovered a bug in one among her homework issues, and he or she was like, “Oh, fascinating.” She was so excited that I had discovered a query that she didn’t know the reply to. She [just said], “Oh my gosh I don’t know, let’s go discover out!” I bear in mind her being this nice professor at MIT, and he or she was excited to search out one thing that she didn’t know and go and study it collectively versus being embarrassed that she didn’t know one thing. I discovered loads from that interplay: That it’s enjoyable to not know one thing as a result of then you definately get to go and discover the reply, and regardless of who you might be, you’re by no means anticipated to know every thing.
