Humanoid robots? a robotics startup founder Says Most won’t Need Legs

In recent years, the two-legged humanoid robot has brought bold visions from industry leaders like tesla or figure.ai of Highly Intelligent robot servants unlockless potential.

A Little-Known startup out in austin says not so fast: The wheeled robot is fine for samp.

Diligent robotics, an austin-based startup founded in 2017, Builds robots for the healthcare Space. Its Wheeled Robot, Moxi, Can Automate Tasks in the Hospital, Such as Delinary Lab samples or Medical Supplies. These are routine but essential chores that vivian chu, co-founder and chief innovation officer of diligent robotics, Says take precious time away from human staff and patients.

“I will think that over time, you’re going to Very Quickly See that the form form factor – like two arms, a head, and a wheel – is probably going to be a form that ends up coversing what you need,” chu toold business insider in an interview.

For moxi, don’t think of a humanoid robot installed with the latest chatgt model, carrying out free-flowing dialogue. Chu Likes to Think of Moxi More As The “Minimum Viable Humanoid” Whittled Down to Focus on Specific Tasks.

That doesn’t mean moxi is simple to build or any teessive.

With more than 90 robots deployed acroSs 25+ Hospitals, chu to told b That diligent’s moxi robots have carried out Over 1.2 million Supply deliverries. The Company Estimates that that is to be to About Half a Million Hours of Human Time Saved.

Business Insider Spoke with Chu About How Diligent Robotics is Meeting Hospitals’ Needs, Where The Technology Needs Improvements, and Why Humanoid Robots Are A Ways From Entering Our Households.

This interview han been edited for Length and Clarity.

How did you get into robotics?

I GREW UP IN THE BAY AREA WITH CLASSIC ENGINEERING PARENTS. In my senior year at Berkeley, I took my first intro to robotics class, where to program a robot. I thought, “damn it, i want to learn more.”

SO I WENT TO PENN FOR A MASTER’S AND THEN TO GEORGIA TECH FOR A PhD. That’s where i met my cofounder, Andrea Thomaz, who was my phd advisor. She’s a leading world expert on how to put robots and people together.

When i met her, we were bot at the stage of life where we thought, “robots are cool. We write papers for say, we will one lab Experiment, and then we just go.” But we wand robots to actually make a difference, like we said in ouur papers.

We decided that the technology was starting to get ready. When Andrea First Started Our Lab, A Robot Cost Half a Million Dollars. By 2015, 2016, You Could Build the Same Robot for $ 80,000 to $ 100,00.

Each now, the cost has dramatically gone down. That’s we decide to start diligent.

Why Hospitals?

We did About 100 to 150 Interviews Across the Market. Really quickly, we homed in on healthcare.

In the Early Days, We Shadowed Nurses and Staff With Clipboards and Stopwatches to See Where Coulds Could Make a Difference. Since before Covid, we found that nurses and clinicians spend up to 30% of their just fetching and gathering supplys, and less than 30% on Direct Patient Care they are so Busy with logistical tasks.

Any time returned to a staff Member meant better patient outcomes. We saw that and thought, “this is where robots should be. This is how you want robots augmenting people as opposed to replacing say.”

How Did You Decide on Moxi’s Design?

When we were fundraising Early in 2017, investors would as, “Why do you have an arm on your robot?”

For us, it was a no-brainer. If you don’t, hospitals would have to modify every single and elevator. Retrofitting A Hospital COULD COST A MILLION DOLLARS AND COULD Take a year.

With an arm, moxi can just push the elevator button directly.

The head is important too. We’re Putting robots in a place where People have never interactions with a robot. Things like Eye Contact, or if i’m looking at my cup, you know i’m going to drink my coffee. A head means the robot can communicate intens. Our Main Sensor for Manipulation is in the Head, so every time it look, it’s’ actively perceiving and communicating intens.

As for the Wheels, Hospitals Are Ada-Compliant. They have ramps and automated doors. Going with a Wheel Form Factor Made Sense. It is statistically stable, safe, and perfect for an Environment with elevators and ramps. If something happy and you power down, you can just roll the robot to the side.

How do Masure SUCCESE HOSPITALS WITH MOXI?

Time and steps saved are probably the first basic metrics.

One of Our Hospital Systems Had Teleboxes – These are Bedside Monitors that Monitor A Patient’s Vital Signs and Have to Be Sentantly. AFTER WE INSTALLED MOXI, Now Everyday Telemetry Box in Three Massive Buildings is Senthough the Robot. There are zero people who run the boxes.

Overall, Mozi Has Made Over 1.2 million Deliveries. Based on average distance and tasks, we estimate that staff would’ve saved Around half a million hours of time walking, Lab samples, or medication around.

Do you Think Humanoid, Legged Robots Are Coming Soon?

Over time, you’re going to see that the form factor with a Head, two arms, and wheels is probably going to cover the majority of tasks. There is an an interesting segment where you will need legs – disaster recovery is one that is to mind, or homes where you have stairs.

It Comes Down to the Workflow. What is the Pain Point? What Can Robots Be Doing 24/7 That Truly Gives People Time Back?

It can be very premium to talk about legged robots because the thing that a warehouse needs might not require legs.

A legged form factor in homes – i see it prety light, far away.

How have investor Conversations Changed in Light of Recent Focus on Bipedal Humanoid Robots?

In the Beginning, investors would As, “Why do you have an arm?” Now they Ask, “Why do you have two arms?” And there are the tasks that will will require a second arm – that on our futmap.

There is some education you have to do with investors-will you go all in general-purpos, or focus on a specific segment? With all deep tech, you just have to find the right investors who undersand the thessis.

Any Broader Advancements in Robots You’re Looking out for?

Battery Technology. Our robots Last About 16 Hours Total With Smart Charging in Between. As we scale computte, power Becomes the bottleneck. I think some of these humanoid companies only have a 90-minute runtime. Then there Safety: Hospitals Care a Lot About the Safety of Your Platform, Like Whether IT COULD CATCH ON FIRE.

That’s what i’d love to see innovation in-safer, longer -lating batteries.

What’s Next for Diligent?

More dexterity is part of the Future Product lines that we’re thinking about. Hospitals want us to do more than transport – Things like assembling case cartes or handling more supplys. Over time, HAVING Other Form Factors Like Two Arms Will Make Sense. Dialogue is Also Something We’re Exploring.

We’re Also Working on Integrating MOXI Directly with Hospital Records. SO instead of someone tapping on an app, a patient admission to automatically trigger a task for the robot.
