What Rollo Robotics Builds
Rollo Robotics is a Tallinn, Estonia startup founded in 2025 by Arno Kütt, the creator of Cleveron, and CEO Sander Sebastian Agur. It builds the 1ROLLO, an outdoor autonomous security robot with an unusual party trick: it balances and drives on a single wheel roughly 60 cm across, kept upright by a proprietary gyroscopic stabilization system with a high-speed flywheel inside the wheel.
The company raised a 3.7 million euro pre-seed round, led by Berlin-based FoodLabs and frontier-tech investor Prototype, to mature the monowheel technology toward production. It plans to sell 1ROLLO as Robotics-as-a-Service — a subscription bundling the machine, software, updates, and support — rather than as an outright hardware purchase. Because this is a very early-stage company, most of what is public traces back to its own announcements; independent field validation is still thin.
The 1ROLLO Security Robot
1ROLLO is aimed at commercial security and surveillance: patrolling properties, perimeters, and industrial sites. Reported specifications include a weight around 45 kg, a top speed near 30 km/h, up to roughly eight hours of battery per charge, and IP65 water resistance. Its sensing and features, as described by the company, include 360-degree computer vision, RTK satellite positioning, autonomous patrol along mapped routes with obstacle avoidance, movement and anomaly detection, license-plate recognition, hazardous-gas monitoring, and a speaker and microphone for remote communication.
The single-wheel design is the differentiator and the open question. Coverage of the reveal leaned on the novelty of the form factor, which is exactly the area — stability, tip-over recovery, and durability in the field — a buyer should want independently demonstrated before treating the security capabilities as proven. Rollo Robotics targets commercial availability in 2027.

Bottom Line
Rollo Robotics is an early-stage Estonian startup whose 1ROLLO monowheel security robot is genuinely novel and genuinely unproven. The pre-seed funding and specifications are on record; real-world durability and paying customers are not. Watch for field trials and named subscribers ahead of its 2027 sales target.
