The most expensive inspection is the one you can't do. For a plant manager staring at a blocked pipe or a rescue team assessing a collapsed structure, the cost of not knowing is measured in downtime, risk, and sometimes lives. RoBoa, a robotics spinout from ETH Zurich, is betting that a soft, snake-like robot that can 'grow' 100 meters into confined spaces is the tool to finally answer those questions. The company has secured over $2.5 million in non-equity funding from Swiss and European innovation programs to move its prototypes from the lab into initial pilot projects [Forbes, 2026].
The wedge is a soft, growing body
RoBoa's core differentiator is its method of locomotion. Instead of wheels, tracks, or rigid joints, the tubular robot uses pneumatic actuation to extend itself from the tip, a process the company calls growing-based locomotion [36kr]. This allows it to navigate winding, cluttered, or slippery environments like pipes, sewers, and rubble piles where conventional robots or human entry are impossible [Venturelab]. The robot's soft, compliant body is inherently safe for explosive atmospheres and delicate structures [13, 2024].
- Extended reach. The system can penetrate up to 100 meters into narrow, hard-to-reach areas, a distance that opens up applications in long industrial pipelines and deep disaster sites [ETH Zurich, Dec 2025].
- Modular sensing. The architecture is designed to carry different sensor payloads and even supply liquids, allowing it to collect custom data for specific inspection or intervention tasks [8, 2026].
- Operator simplicity. The company claims the design is easy to operate, aiming to reduce the specialized training typically required for complex robotic systems [8, 2026].
The technology originated in ETH Zurich's Autonomous Systems Lab, and the founding team of four D-MAVT (Mechanical and Process Engineering) graduates brings deep technical credibility in robotics and automation [ETH Zurich, Dec 2025][startupticker.ch].
A funding stack built on grants, not equity
RoBoa's financial runway to date has been assembled almost entirely from non-dilutive sources, a common path for deep-tech spinouts in Europe. The company's disclosed capital includes a CHF 150,000 pre-seed award from Venture Kick in April 2025, which was framed as funding to expand applications in industrial assessment and emergency response [Venture Kick]. Beyond that, RoBoa has raised more than $2.5 million from backers including the Innosuisse Startup Innovation Project, the ESA BIC (European Space Agency Business Incubation Centre), and the ETH Pioneer Fellowship [Forbes, 2026].
| Metric | Value |
|---|---|
| Venture Kick Pre-seed | 0.167 M USD |
| Innosuisse/ESA BIC/ETH Fellowships | 2.5 M USD (estimated) |
The dual-path business model
The company is pursuing a two-pronged go-to-market strategy, splitting its focus between one-time hardware sales and recurring software revenue. According to Venturelab, RoBoa plans to sell robots directly to rescue agencies while offering a subscription model for industrial inspection services [Venturelab]. This hybrid approach attempts to balance the lumpy, project-based nature of emergency response with the more predictable, ongoing needs of industrial plant maintenance.
Where the go-to-market gets narrow
For all its technical promise, RoBoa's path to commercial scale faces predictable hardware startup challenges. The most immediate is proving the reliability and durability of a soft robotic system in the harsh, unpredictable environments it is designed for. Pilot projects are underway, but public details on specific customers or deployment results are not yet available [ETH Zurich, Dec 2025].
| Competitor | Primary Focus | Key Differentiator |
|---|---|---|
| Sarcos Robotics | Industrial exoskeletons & robots | Mature Guardian S snake-arm robot for hazardous environments |
| GE Aerospace (OC Robotics) | Nuclear, aerospace, oil & gas | Long-established provider of serpentine arm systems |
| RoBoa | Confined space inspection & rescue | Soft-body, growing locomotion for extreme accessibility |
RoBoa's answer to these established players is its unique form factor and the safety advantages of a soft, pneumatic system. The company's ideal customer profile is a mid-to-large industrial operator in sectors like chemicals, energy, or wastewater, where regulatory pressure and asset criticality justify investing in advanced inspection tools.
The next twelve months
The coming year is about transitioning from pilot projects to named, referenceable customers. The key milestone to watch is the announcement of a first commercial deployment, either with an industrial partner or a public safety organization. Given the capital-intensive nature of hardware development, a move beyond grants to a priced equity round led by institutional deep-tech or industrial automation investors would be a logical next step to fund scaled production and a commercial team.
