Security robots usually look like rolling kiosks or mechanical dogs. Estonia’s Rollo Robotics is betting that the next patrol machine needs only one wheel.
The startup unveiled 1ROLLO in July 2026 as a functional prototype for industrial sites, data centers, airports, campuses, hotels, and construction zones.
Rollo says a vertically mounted internal flywheel, sensor fusion, and balance software keep the machine upright. Commercial availability is planned for 2027 through a subscription model.
The concept follows AbacusNews.com’s report on robot security patrols replacing overnight guard shifts in Atlanta. 1ROLLO pushes the same labor shift into a slimmer machine built for speed, remote monitoring, and lower operating costs.
One Wheel Changes The Patrol Economics
Most autonomous security robots use four wheels, tracks, or legs.
Its main wheel is roughly 60 centimeters wide. A high-speed flywheel spins vertically inside the chassis. Tilting that internal mass lets the robot lean into turns. Computer controls constantly correct balance as the machine accelerates, slows, or changes direction.
New Atlas’ 1ROLLO security robot report says the prototype uses 360-degree computer vision and RTK-GNSS positioning to follow mapped routes. Cameras and onboard sensors detect obstacles and flag unusual activity.
| 1ROLLO Feature | Reported Specification | Security Value |
|---|---|---|
| Maximum speed | 30 km/h | Covers large sites faster |
| Runtime | Up to eight hours | Supports long patrol windows |
| Weight | About 45 kg | Smaller patrol footprint |
| Weather rating | IP65 | Handles dust and water exposure |
| Connectivity | 4G, 5G, Wi-Fi | Sends alerts to remote teams |
| Navigation | Vision plus RTK-GNSS | Follows mapped patrol routes |
AI Watches, Humans Still Decide
1ROLLO is autonomous in movement, not authority.
When cameras identify unusual activity, the system alerts a remote operator. That person can inspect video, speak through the robot’s microphone and speaker, or dispatch an onsite guard.
This hybrid model matters. Computer vision can flag movement, loitering, objects, or route changes. It cannot reliably know whether every unusual event represents a threat. Human review remains the checkpoint between detection and intervention.
Fleet software is meant to let one operator monitor several robots. One remote employee could supervise multiple zones instead of paying one guard to walk each route.
The Business Model Matters As Much As The Wheel
Rollo Robotics was founded in 2025 by Arno Kütt and Sander Sebastian Agur. In January 2026, it raised €3.7 million in pre-seed funding led by FoodLabs and Prototype, with backing from Enterprise Estonia’s RUP program.
The funding is aimed at hardening the platform for extreme weather and high-traffic settings, preparing suppliers, and moving from prototype work into commercial production. An engineering report details its speed, battery life, gyroscopic stabilization, and 2027 launch.
Rollo intends to sell through Robotics-as-a-Service rather than asking customers to buy hardware outright. A subscription can bundle the machine, software, updates, maintenance, and support into one operating expense.
That structure lowers the barrier for many property owners.
The Prototype Still Has To Prove Itself
The design is clever, but commercial security depends on reliability.
A one-wheel robot must recover safely from potholes, curbs, debris, slippery pavement, network loss, battery degradation, vandalism, and sensor failure. Eight hours of claimed runtime may shrink in cold weather or during faster patrols. Parking structures and dense buildings can complicate satellite positioning.
Privacy raises another issue. A mobile camera can follow people, record activity, and move closer than a fixed surveillance camera. Customers will need clear policies covering footage storage, operator access, audio recording, facial recognition, and police requests.
Rollo has not published large-scale independent field data showing incident reduction, false-alert rates, uptime, or total cost against human guards. Those numbers will matter more than the novelty of the wheel.
Security May Become A Fleet Subscription
1ROLLO points to a broader change in private security. Buyers may stop purchasing cameras, patrol vehicles, and guard hours as separate products. They may subscribe to a connected fleet combining mobile sensors, remote operators, AI alerts, and human response.
The monowheel design could make that fleet cheaper, faster, and easier to place in tight spaces. It could fail if real sites expose balance, durability, or safety limits that prototype demonstrations do not show.
The strongest part of 1ROLLO is the operating model behind it: autonomous movement, centralized human judgment, and recurring service economics. If Rollo can prove reliability before its planned 2027 launch, the next security system may arrive as a subscription that rolls its own patrol route.
