The people who keep facilities running carry a lot of repetitive work. We build robots to take some of it on, so your team has more time for the work that needs their attention.

The A1 ADIBOT can map a space and choose its own disinfection points, or navigate points your team sets in advance. It can also leave its dock and run a scheduled UV-C cycle on its own. It adds a consistent layer to routine manual cleaning and disinfection.

Robots are what we make. Partnership is how we work. That means staying by your side well beyond deployment, with ongoing support focused on your team's success.

The germicidal effect of UV-C light has been known for over a century, but the way it actually works is different from what most people picture.

It isn't heat, and it isn't a chemical. UV-C is a specific band of light, energetic enough to damage a microorganism's genetic code. The cell stays intact. It just loses the ability to replicate, and something that can't copy itself can't spread.

Here's what actually happens.

AHE is in the books.

We spent a few days in New Orleans talking with teams and individuals about where autonomous UV-C disinfection fits into their operations. A few highlights from the show floor:

→ Live demo of the A1 ADIBOT at the booth
→ A raffle drawing that made someone’s day — congrats to our winner Joli!
→ Closing it out with a private reception for the teams and partners who make this industry move

Thank you to everyone who stopped by our booth!

AHE Exchange is one of the few places teams can see autonomous UV-C disinfection up close.

We're bringing the A1 ADIBOT to Booth 209 in New Orleans. Stop by to see how it navigates a floor plan on its own and how our UV-C autonomous disinfection robot fits into a real disinfection program.

While you're there: raffles, gachapon pulls, merch, and a few giveaways we haven't announced yet.

If your team is evaluating autonomous UV-C, this is a good place to start that conversation in person.
See you at Booth 209.

UV-C light doesn't distribute evenly across a space. Distance determines irradiance, and the relationship is not gradual.

This is governed by the Inverse Square Law, a fundamental principle of physics: as UV-C light radiates outward from its source, the same energy spreads across a progressively larger area. The result is a rapid decline in irradiance with every step back from the source.

In practical terms: double the distance, and irradiance falls to roughly 1/4 of its output at the source. Triple it, and irradiance drops to approximately 1/9.

For fixed-position UV-C emitters, this creates a structural challenge. Surfaces close to the source receive concentrated irradiance. Surfaces further away may receive irradiance levels too low to accumulate an effective dose when time is limited, with no mechanism to compensate once a cycle is underway.

This is where autonomous positioning becomes a meaningful variable. The ADIBOT A1 navigates to multiple points within a space, bringing the source closer to the surfaces that require it. Rather than working around the physics, it accounts for them — systematically, and without operator intervention.

Understanding the law is the first step to applying it effectively.

UV-C disinfection only works if it happens in an empty room. The A1 ADIBOT is built with that as a hard requirement, not an assumption.

PIR Motion Sensors detect heat and motion in the space and automatically pauses the disinfection cycle if someone enters.

Smart Safety Sign is placed at the room's entry point as a visible warning sign and also pauses disinfection when moved.

LiDAR Sensors give the A1 continuous awareness of its surroundings for navigation and obstacle detection.

No single sensor carries the whole job. Safety is layered by design.

Consistency starts with understanding the basics.

UV-C intensity drops as distance increases, following the Inverse Square Law. Even a small change in placement can meaningfully affect how much energy actually reaches a surface.

Geometry, shadowing, and surface orientation all add real-world complexity, but the core principle holds: where you place the light determines the dose the surface receives.

That's why positioning gets treated as a variable to control, not an afterthought.

Not every room calls for the same disinfection approach, and the A1 ADIBOT isn't built around just one protocol.

Use Map follows a pre-mapped disinfection program, so recurring disinfection runs are repeatable and consistent.

Auto-Explore determines evenly distributed disinfection points on the fly, which is best for environments that rearrange between cycles.

On-The-Spot holds the A1 in place for targeted treatment at a single point for spot treatment.

Three ways to run the same robot, so the mode fits the needs of the task.

UV-C disinfection looks simple: turn on a light, walk away. The physics underneath it is not.

At 254 nm, UV-C energy is absorbed directly by microbial DNA and RNA. That absorption causes the formation of pyrimidine dimers that block replication, which is how the organism is inactivated.

But the science only holds up if the ex*****on does too. Timing, placement, and line-of-sight coverage determine whether a program delivers a consistent dose everywhere it's needed, or leaves gaps a UV-C cycle can't see around.

For facilities leaders, understanding this mechanism isn't academic. It's what separates a protocol that looks good on paper from one that holds up under real deployment conditions.

No two facilities run the same way: different floor plans, different protocols, different teams already juggling more than one priority. We built the A1 ADIBOT to adapt to that reality, not the other way around.

3 Operating Modes let the A1 match how your space actually operates, from navigating point-to-point for autonomous disinfection to spot treatment for single-point use cases..

ADIS gives your team cloud-based task reporting and fleet management, so oversight happens from a dashboard, not from standing next to the robot.

Layered Safety combines onboard motion sensors with smart safety signage, so the disinfection cycle responds the moment someone enters the space.

Control shouldn't mean more manual work for your team. It should mean the robot fits into the systems you already have.
