Not lengthy after the 1918 Spanish flu pandemic, Czech author Karel Čapek first launched the time period “robotic” to explain synthetic individuals in his 1921 sci-fi play R.U.R. Whereas we’ve not but created the extremely smart humanoid robots imagined by Čapek, the robots mostly used as we speak are advanced methods that work alongside people, aiding with an ever-expanding set of duties.

In a chunk in Nature Machine Intelligence, Johns Hopkins researchers focus on how the coronavirus pandemic has pushed sudden improvements in automation, whereas on the similar time revealing bottlenecks to deploying robotic methods in well being care settings. They contend that advances in human-robot interplay—akin to bettering robots’ capabilities to really feel, contact, and determine—will decide if the robots of tomorrow will assist hospitals keep forward of the subsequent pandemic.

Within the commentary, the crew identifies 3 ways robots have significantly enhanced affected person care and supplier security throughout COVID-19: minimizing contact between contaminated sufferers and care suppliers, lowering the necessity for PPE, and giving suppliers extra time to concentrate on essential duties. They look forward to how applied sciences may be leveraged to develop adaptable and dependable robots for future infectious illness crises.

The Hub reached out to commentary authors Axel Krieger and Russell Taylor of the Whiting College of Engineering, and Brian Garibaldi, director of the Johns Hopkins Biocontainment Unit at Johns Hopkins Medication, for insights on the way forward for robots throughout infectious illness outbreaks.

What has the well being care robotics group discovered throughout this disaster?

Taylor: You go right into a pandemic with the robots you’ve got, not the robots you would like you had. We will not construct a fleet of robots for an emergency and put them in a warehouse. Not solely is that not economically viable, however by the point you want them, they could possibly be out of date. One factor we acknowledged is that we have to construct core capabilities into deployed methods that may be simply tailored for the challenges of the second.

We already had robots that delivered meals or may take a affected person’s temperature. Now we’re speaking about way more subtle methods—that may do critical cleansing, that may carry out nursing duties, that may do many issues past simply delivering provides—and that presents some attention-grabbing engineering challenges.

A giant problem has been deployability and the way rapidly a non-expert consumer can customise a robotic. For instance, our ICU ventilator robotic was designed for one form of ventilator that pushes buttons. However some ventilators have knobs, so we’d like to have the ability to add a modality in order that the robotic may manipulate knobs. Say you need one robotic that may service a number of ventilators; you then’d want a cellular robotic with an arm attachment, and that robotic may additionally do loads of different helpful jobs on the hospital flooring.

Future robots will play a extra vital function in medical take care of infectious illness, however there are nonetheless obstacles to have robotic instruments prepared for when the subsequent pandemic hits. The place ought to engineers focus their analysis efforts to make sure we’re ready?

On the peak of the coronavirus pandemic final 12 months, engineers at Johns Hopkins debuted a robotic able to remotely working ventilators and different bedside machines from exterior of affected person ICU rooms

Krieger: The pandemic has proven among the present limitations of robotic methods to robustly work and adapt in tough, altering environments at giant scales. Robots in busy hospitals want to have the ability to handle sudden occasions and uncertainty. Analysis must concentrate on advancing the autonomy and studying methods for well being care robots, to allow them to carry out duties with solely restricted supervision. Probably the most life like strategy for well being care robots within the close to future is shared autonomy, which mixes the data of medical consultants with the capabilities of robots.

The place are greatest alternatives for robots to assist frontline well being care employees? Which duties will likely be most useful?

Garibaldi: A human supplier must placed on recent PPE each time they enter the room the place an infectious affected person is being handled. Robots needn’t put on PPE, in order that frees up invaluable provides and time for human suppliers. The extra robots can do, the extra it permits human suppliers to dedicate their consideration to different features of care.

I believe a giant space that engineers ought to concentrate on is enhancing the power of robots to carry out advantageous motor duties, to allow them to carry out direct affected person care duties akin to inserting an IV, intubating the trachea, or inserting central strains. Different potential duties may embrace fundamental room cleansing, phlebotomy, and ventilator and monitor administration and manipulation.

What function ought to care suppliers and sufferers play within the design of those robotic methods to make sure they’re efficient and secure?

Garibaldi: Care suppliers and sufferers have to be comfy each with the performance of robotic methods in addition to the precise human-robot interface. There are particular duties that sufferers would possibly favor to be carried out by a human clinician. Along with job choice, sufferers and caregivers can present necessary suggestions in regards to the supplies utilized in robotic building—significantly in parts that straight contact a human affected person—in addition to total design.

Taylor: They have to be concerned in each step of the method. Engineers want suggestions on how these methods actually work within the wild. We additionally wish to perceive their reactions to the methods, particularly if a caregiver says, “I am unsure I can belief a robotic to try this.”

What are you researching proper now associated to this problem?

Taylor: I am within the query of cellular autonomy and situational consciousness: how can a pc develop sufficient details about the surroundings in order that it might do the duty it’s alleged to do, and the way can it relate its normal movement and sensing capabilities to that particular job? If I inform a robotic to wash a room, the robotic wants to have the ability to perceive what’s within the room and what must be cleaned, and that modifications from daily and room to room. Within the Laboratory for Computational Sensing and Robotics, we’ve groups investigating how augmented actuality can improve human-robot collaboration. Many are working within the context of surgical robots, however there may be loads of overlap with medical care functions.

Krieger: Our crew is engaged on enhancements for our ICU robotic to supply larger accuracy and better constancy operation of ventilators. We’re additionally investigating using robots in performing lung ultrasound imaging utilizing 3D cameras and power sensors. Lastly, we’re engaged on different autonomous surgical robotic procedures, akin to suturing and tumor resections.


The present pandemic highlights how distant healthcare robots could possibly be useful sooner or later
