Rollo Robotics, an Estonian startup developing an autonomous monowheel security robot, has raised €3.7 million in pre-seed funding that will be used for further maturing the company’s gyroscopic stabilisation technology.
The round was led by Berlin-based FoodLabs and Frontier Tech VC PROTOTYPE, and supported by Enterprise Estonia’s RUP programme.
According to the company, the funding will be used for maturing its gyroscopic stabilisation technology and transitioning it from research and development towards commercial production.
The company says it has successfully mastered the “stability paradox” of the monowheel.
“By utilising high-frequency sensor fusion and proprietary balance control, the Rollo security robot offers a slim, agile profile capable of navigating tight urban spaces and complex industrial corridors where traditional robots fail,” the company said in a statement.
It now aims to bring the technology to the global security market with the goal to make autonomous patrolling “more cost efficient, less intrusive and more versatile”.
Rollo Robotics was founded in 2025 by Arno Kütt and Sander Sebastian Agur. It’s based in Tallinn, Estonia.
