GreenBeam Safety Hero

Safety

Designed for ground where people live.

GreenBeam works on lawns and beds where children play and dogs sleep. Safety shaped the hardware, not the footnotes.

Beam stays enclosed Sees what is around it Nothing sprayed
GreenBeam Safety Contained

Contained

The beam stays inside the machine.

GreenBeam's treatment system sits inside a sealed housing, low to the ground, pointed down. The beam travels from the source, through the aperture, to a plant a few centimeters below. It does not travel across your lawn, and it does not leave the machine.

Nothing happens until GreenBeam has already confirmed what it is looking at. Detection comes first, confirmation second, treatment last. If the first two do not complete, the third never starts.

Close view of the GreenBeam treatment head recessed inside its sealed housing, facing downward. Aperture, recessed and downward facing

The treatment aperture sits set back inside the housing, behind the front skirt, facing the ground. There is no exposed emitter on any outer surface of the robot.

Enclosed housing

The source, the optics and the aperture sit inside a sealed assembly. There is no exposed emitter anywhere on the outside of the robot.

Pointed at the ground

Treatment is directed downward, at ground level, into a working area a few centimeters deep. There is no horizontal path out of the machine.

Confirmed first

GreenBeam identifies the plant, confirms it is a target, then acts. No confirmation means no treatment.

The part that reassures most parents is the simplest one. The beam never leaves the machine.

GreenBeam Safety Detection

It sees you

Something enters the area. GreenBeam stops.

LiDAR and onboard sensing give GreenBeam a continuous picture of what is around it. A foot, a ball, a dog, a garden hose that was not there yesterday. When something enters the working area, the mission pauses before anything else happens.

GREENBEAM OBSTACLE DETECTED
Patrolling
01

Continuous awareness

GreenBeam is not checking occasionally. Spatial sensing runs the whole time the robot is moving.

02

Stop, then decide

The first response to anything unexpected is to stop. Replanning and route changes come after, not instead.

03

Boundaries hold

The operating area you drew in the app is enforced continuously, so GreenBeam stays where you put it.

Nothing sprayed

The safest thing about GreenBeam is what it never puts down.

Every other safety claim on this page describes how carefully a machine behaves. This one is different. GreenBeam applies nothing to your lawn, so there is nothing left behind for anyone to encounter afterward.

Children playing safely in a front yard

Hands on the grass, five minutes after GreenBeam finished. No re-entry interval, because there is no treated surface to wait on.

  • No re-entry interval

    No waiting for the lawn to dry before children or pets can go back out on it. There is no treated surface to wait on.

  • Nothing on bare feet or paws

    No residue to pick up on skin, fur, or the soles of shoes, and nothing to track through the house afterward.

  • Nothing in the storm drain

    No product to run off the lawn in the next rain, and nothing to reach the creek at the end of the street.

  • Nothing in the garage

    No concentrate to store on a shelf, no sprayer to rinse, and no half-empty containers to keep out of reach.

A chemical program asks you to manage the risk after it leaves. GreenBeam removes the step that creates it. There is nothing to keep anyone away from.

GreenBeam Safe Operating States

Safe operating states

When GreenBeam is not sure, it stops.

An autonomous machine needs a defined answer for every condition it did not expect. GreenBeam's control logic has one rule that governs all of them, and six states where it applies.

Obstacle detected

Stop, then replan.

Motion halts first. Only after the area is clear does GreenBeam decide whether to route around or wait.

Perception
Rain detected

End the mission early.

GreenBeam suspends work and heads for the Garage rather than continuing in conditions it was not designed for.

Weather
Boundary approach

Stay inside the line.

The operating area you drew in the app is enforced continuously, not checked occasionally.

Position
Position confidence falls

Pause rather than guess.

If GreenBeam is less certain where it is, it enters a conservative state instead of carrying on blindly.

Localization
Low battery

Get home first.

Return to the Garage takes priority before the remaining charge becomes the limiting factor.

Energy
Target not confirmed

Do nothing at all.

No treatment happens without a confirmed target. Uncertainty produces inaction, never action.

Interlock

Uncertainty should reduce action, not increase it. That single principle runs through every subsystem on the robot. It is the reason a machine carrying a treatment system can be trusted to work unattended on ground where your family spends its weekends.

GreenBeam Safety Certification

Certification

The standards GreenBeam is built to meet.

Products like GreenBeam are regulated, and that is a good thing. Here is the framework, in plain language, and where GreenBeam sits inside it.

FDA CDRH 21 CFR 1040

The federal performance standard for laser products sold in the United States, administered by the FDA's Center for Devices and Radiological Health. It governs enclosure, labeling, interlocks and reporting before a product enters commerce.

In progress
FCC Part 15 Electromagnetic

Confirms GreenBeam's electronics do not interfere with other equipment in and around your home.

In progress
UL or ETL Electrical safety

Independent testing of electrical safety across the Robot and the Garage, including charging behavior.

In progress
UN38.3 Battery transport

The transport standard every lithium battery must satisfy before it can be shipped to a customer.

In progress
Ingress protection Weather sealing

Rated resistance to dust and water, tested against the conditions an outdoor machine actually meets.

Validation

What we will publish, and when. GreenBeam publishes safety and performance figures once they are measured, not before. That is the same standard applied across the engineering validation program, and it is the reason this page describes design intent and certification pathway rather than quoting numbers that have not been tested yet.

Certification completes during production engineering. Results will be published here as each one closes.
