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 medicines and wound dressings between departments to save lots of the medical employees’s time. Diligent has simply closed their Collection B funding spherical with $30 million. 

We sat down with Dr. Thomaz to speak about Moxi, how one can handle individuals’s expectations about robots, and recommendation for younger individuals and girls in robotics. This interview has been frivolously edited for readability. 

What sorts of issues are you making an attempt to resolve with Moxi?

We’re constructing Moxi to assist hospitals with the huge 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 fair greater downside 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 individual’s job in a hospital that you’d truly need to give over to automation or robots, however there are tiny little bits of lots of people’s jobs which might be completely capable of be automated and that we can provide 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 numerous stuff that’s transferring round each day. Each individual within the hospital goes to have sure medicines that have to be delivered to them, sure lab samples that have to be taken and delivered to the central lab, sure provides that want to come back as much as them, meals and diet each day. You have got numerous stuff that’s coming and going between affected person items and all these completely different help departments. 

Each considered one of 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 completely different nursing items. So generally that’s going to be a nurse that simply must get one thing for his or her affected person and so they need that to occur as quickly as potential. They’re making an attempt to discharge their affected person, they want a specific wound dressing package, they’re going to run down and get it as a result of they need 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, numerous instances 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 form of falls between these departments. There’s completely different individuals that will be concerned however numerous instances 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?

Over the past 6-12 months, the demand has actually skyrocketed such that we’re barely maintaining with the demand for individuals eager to implement robots of their hospitals. That’s the explanation why we’re elevating this spherical of funding, increasing the staff, and increasing our capacity to capitalize on that demand. A few years in the past, if we had 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, however it actually wasn’t the very first thing that each hospital CIO was fascinated about. Now that has fully 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 need to find out about your resolution.” Via the pandemic, I believe everybody has seen that the workforce scarcity in hospitals is barely getting worse within the close to time period. All people desires to plan for the longer term and do every part they’ll to take small duties off of the plates of their medical 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 longer term, 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 affect my groups.”

[Two of our investors are hospitals, and] that’s been considered one of our most enjoyable 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 need to construct this alongside you” — it’s fairly thrilling to have prospects like that. 

What sorts of technical issues did you run into once you had been both constructing Moxi or deploying it in a hospital atmosphere? How did you remedy these issues? 

One which was virtually shocking in how typically it got here up, and actually impacted our capacity [to run Moxi in the hospital environment] as a result of we’ve a software-based robotic resolution 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 programs to have the ability to use WiFi, backup to LTE if we’ve to, however be sensible about that so we’re not spending a complete bunch of cash on LTE information. That was an issue that appeared very particular to hospitals specifically.

One other one was safety and compliance. We simply didn’t know what among the completely different necessities had been for hospitals till we truly obtained into the environments and began interacting with prospects and understanding what they wished to make use of Moxi for. Once we had been first doing analysis trials in 2018 or 2019, we had a model of the robotic that was somewhat bit completely different than the one we’ve at this time. It had plenty of open containers so you could possibly simply put no matter you wished to on the robotic and ship it over to a different location. We shortly realized that that restricted what the robotic was allowed to hold, as a result of a lot of what [the customers] wished was to grasp who pulled one thing out of the robotic. So now we’ve an RF badge reader on the robotic that’s related to locking storage containers which might be solely going to open in the event you’re the type of individual that’s allowed to open the robotic. That was an fascinating technical problem that we didn’t find out about till after we obtained on the market. 

How did you’re employed with nurses and the opposite healthcare professionals you had been working with to determine what could be probably 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 atmosphere. We spent the primary 9 months of the corporate in 2018 constructing out our analysis prototype. It appeared loads like what Moxi appears like at this time. Beneath the hood it was fully completely different than what we’ve at this time when it comes to the reliability and robustness of the {hardware} and software program, however it was sufficient to get that platform out and have it deployed with nursing items. We embedded ourselves with 4 completely different nursing items throughout Texas over a year-long interval. We might spend about 6-8 weeks with a nursing division, and we had 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 need a robotic like this to do?” A part of this that was actually vital was they didn’t have good concepts about what they’d 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’d have good concepts of what they’d need the robotic to do. Then we’d 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 prefer 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 respected for the robotic to do was connecting the nursing items to those different departments. We can assist a nurse with provide administration and getting issues from place to put inside their division, or we can assist them with issues which might be coming from actually distant. [The second one] was truly impacting their time approach far more.

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

We do numerous demonstrations, however nonetheless with virtually each single implementation you get questions on some robotic in Hollywood, [and you have to say] “No, that’s the films” 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 need to talk a extremely excessive degree of intelligence. There are many canned phrases and interactions on the iPad as a substitute of by way of voice, and numerous instances 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 massive analysis subjects that we had for quite a few years was embodied dialogue — how robots might have an actual dialog with individuals. I had an excellent appreciation for the way laborious that downside is, and likewise for simply how a lot individuals need it. Individuals come as much as a robotic, and so they need it to have the ability to speak 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 govern that factor,” which we predict is vital. It’s actually about putting that steadiness. 

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

The distinction between analysis and observe. On the one hand, the motivation and purpose for beginning an organization is that you simply need to see the sorts of issues that you simply’ve finished within the analysis lab actually make it out into the world and begin to affect actual individuals and their work. That’s been some of the 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! When you simply cling again and watch Moxi come and do a supply, virtually all the time individuals are tremendous excited to see the robotic. They get their supply and so they’re like, “Oh, thanks Moxi!” That looks 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 best way out into the world. 

That being stated although, there’s a lengthy tail of issues that it’s a must to remedy from an engineering perspective past [developing a feature]. My VP of engineering Starr Corbin has this smart way of placing it: The analysis staff will get a sure factor on the product to be characteristic full, the place we’ve demonstrated that this characteristic works and it’s a superb resolution, however then there’s this entire part that has to occur after that to get the characteristic to be manufacturing prepared. I’d say my largest lesson might be every part that it takes, and the whole staff of individuals it takes, to get one thing from being characteristic 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 favored to offer girls in robotics, in academia, and simply type of pursuing issues usually. Imposter syndrome is actual, and everyone feels it. All you are able to do to fight it isn’t underestimate your self. Converse up and know that you simply deserve a seat on the desk. It’s all about laborious work, but in addition ensuring that your voice is heard. A number of the mentorship that I gave to numerous my girls grad college students after I was a professor was round talking engagements, talking types, and communication. It may be actually uncomfortable once you’re the one something within the room to face up and really feel such as you should be the one talking, and so the extra that you simply observe doing that, the extra snug it could possibly really feel, the extra assured you’ll really feel in your self and your voice. I believe discovering that assured voice is a extremely vital 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 speak. I for some purpose obtained to take her out to lunch on my own, so we had this wonderful one-on-one. We talked somewhat bit about her speak, in all probability half of the lunch we talked about technical issues, after which she simply type of turned the dialog [around] and stated “Andrea, don’t overlook to have a household.” Like, don’t overlook to give attention to that a part of your life — it’s crucial factor. She obtained on a soapbox and stated “You must have a piece life steadiness it’s so vital. 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 frightened about nothing however success. It was actually highly effective to have any individual sturdy and influential like that telling you “No, no, that is vital and you might want to give attention to this.” 

The opposite individual that’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 considered one of 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 seek out one thing that she didn’t know and go and find out about it collectively versus being embarrassed that she didn’t know one thing. I realized loads from that interplay: That it’s enjoyable to not know one thing as a result of then you definitely get to go and discover the reply, and irrespective of who you might be, you’re by no means anticipated to know every part.
