Rollo Robotics, an emerging deep tech startup focused on next-generation autonomous mobility, has raised €3.7 million in pre-seed funding to accelerate the development and commercialisation of what it calls the world’s first stable autonomous monowheel security robot. The round was led by Berlin-based FoodLabs and frontier technology investor Prototype, with additional support from Enterprise Estonia’s RUP programme.
Founded in 2025 by robotics pioneer Arno Kütt and technologist Sander Sebastian Agur, Rollo Robotics aims to disrupt the global security robotics sector through a completely new category of robotic mobility. Kütt, known for founding Cleveron, an internationally recognised Estonian robotics company specialising in parcel automation and retail robotics, brings years of experience in engineering and large-scale hardware deployment. Agur, meanwhile, contributes deep expertise in technology strategy and autonomous systems.
A Breakthrough in Robotic Mobility
The core innovation behind Rollo Robotics is its single-wheel autonomous platform, a stark departure from the multi-wheeled and tracked systems that dominate today’s security robotics market. Historically, monowheel vehicles have been notoriously difficult to stabilise, long considered more of an engineering curiosity than a practical mobility solution. Rollo claims to have solved this challenge through a proprietary combination of high-frequency sensor fusion, advanced gyroscopic stabilisation, and dynamic balance control.
This breakthrough enables the robot to maintain exceptional stability while offering a slim, highly manoeuvrable profile. According to the company, the monowheel design allows the robot to navigate spaces where conventional robots struggle, such as narrow corridors, dense industrial facilities, and complex urban environments. Its compact footprint also makes it less intrusive and allows for more discreet security operations.
Sander Sebastian Agur, co-founder of Rollo Robotics, describes the accomplishment as “a milestone for autonomous mobility and the entire robotics sector.” He emphasises that the company’s mission is to make autonomous patrolling “more cost efficient, less intrusive, and significantly more versatile” through a modernised robotic platform built from the ground up.
Fueling Technology Development and Production Scaling
The newly raised €3.7 million will support two major development tracks, technological maturation and production readiness. On the technology side, Rollo will focus on enhancing performance in challenging real-world conditions, including extreme weather, busy industrial sites, and high-traffic public areas. This involves refining sensor systems, optimising navigation algorithms, and strengthening the robot’s mechanical and electronic architecture.
Simultaneously, the company will invest in supply chain development, component refinement, and the establishment of manufacturing processes necessary to meet rising demand from early pilot partners. Moving from advanced R&D into scalable production is a critical milestone as the company positions itself for broader commercial deployment.
Why the Market Is Paying Attention
The security robotics sector is experiencing rapid growth as organisations seek cost-effective, continuous monitoring solutions amid rising labour shortages and increasing threats to physical infrastructure. Autonomous security robots are increasingly used for patrolling large campuses, logistics hubs, data centres, and critical infrastructure. Rollo’s differentiated design positions it as a potential challenger to traditional multiwheel robotic platforms, offering new capabilities in agility, access, and long-duration autonomous operation.
Prototype investor Andreas Klinger highlighted the growing need for resilient security technologies, noting that Western companies face “rapidly growing hybrid threats” and require scalable solutions capable of augmenting human security teams. FoodLabs echoed this sentiment, pointing to significant inefficiencies in today’s security sector and praising Rollo’s engineering approach as an example of Estonia’s rising influence in deep tech innovation.
Looking Ahead
With fresh capital in place, Rollo Robotics is preparing to expand pilot programmes with early adopters while pushing toward full commercial readiness. The company believes its monowheel platform represents not just a new robot but the foundation of an entirely new mobility category within the security industry.
As the global market for autonomous security systems continues to accelerate, Rollo Robotics aims to position Estonia at the forefront of deep tech innovation, proving that even a single wheel, properly engineered, can carry a major technological shift.
