Insider Brief
- Rollo Robotics has raised €3.7 million in pre-seed funding to transition its autonomous monowheel security robot from advanced R&D toward early commercial production, according to the company.
- The round was led by FoodLabs and PROTOTYPE, with support from Enterprise Estonia’s RUP program, following the company’s emergence from stealth after its 2025 founding.
- Rollo plans to use the capital to harden its gyroscopically stabilized monowheel platform for real-world security environments and to prepare manufacturing and supply chains for pilot-driven production scale-up.
Rollo Robotics, an Estonian deep-tech startup developing an autonomous monowheel security robot, has raised €3.7 million in pre-seed funding to move from advanced research into early commercial production, according to the company.
The round was led by FoodLabs and PROTOTYPE, with support from Enterprise Estonia through its RUP program. The funding follows the company’s emergence from stealth after its founding in 2025, according to the company.
Based in Tallinn, Rollo Robotics is focused on a narrow but technically demanding problem: stabilizing a single-wheel robotic platform for autonomous operation. Most mobile security and inspection robots rely on multi-wheel designs for balance and redundancy. Rollo said its approach centers on gyroscopic stabilization combined with high-frequency sensor fusion and proprietary balance-control software, allowing the robot to operate on a single wheel while remaining upright.
The company said the design enables a slimmer physical profile that can navigate narrow urban spaces, crowded industrial corridors, and constrained environments where larger platforms struggle. Rollo positions the system for security and surveillance use cases, including autonomous patrolling of infrastructure and industrial sites.
The new capital will be used primarily for two purposes, the company noted. First, the company plans to harden its hardware and software for operation in less controlled environments, including adverse weather and high-traffic settings. Second, Rollo aims to prepare its supply chain and manufacturing processes for limited-scale production tied to early pilot deployments, according to the company.
Rollo was founded by Arno Kütt, known for his earlier work on automated retail systems at Cleveron, and Sander Sebastian Agur. The company has not disclosed customer contracts or deployment volumes, but said pilot programs are underway and informing design decisions as it moves toward production readiness.
The investors backing the round are positioning the company within Europe’s broader push to commercialize frontier robotics and physical-AI systems. FoodLabs, while best known for food-system investments, has increasingly backed hardware and industrial automation startups. PROTOTYPE focuses on early-stage European deep-tech companies and typically invests at the pre-seed and seed stages.
“Mastering the physics of a stable monowheel is a milestone for autonomous mobility and the entire robotics sector,” Sander Sebastian Agur, Co-Founder of Rollo Robotics, said in the announcement. “With the backing of FoodLabs and PROTOTYPE, two investors who are at the heart of the European deep-tech ecosystem, we have the resources to bring this technology to the global security market. Our goal is to make autonomous patrolling more cost-efficient, less intrusive, and significantly more versatile by creating a modern robotic platform.”
