Robodex

What Robodex does

Robodex Inc. (株式会社ロボデックス) is a privately held Japanese technology company founded in June 2019 and headquartered in Yokohama, Kanagawa Prefecture. The company designs and manufactures hydrogen fuel cell-powered unmanned aerial vehicles, with its flagship product being the aigis one drone, the only hydrogen drone domestically permitted in Japan, offering 80-120 minutes of flight time (approximately 5x lithium-ion battery drones), 5-10kg payload capacity, and a PEMFC 2400W fuel cell with a high-pressure composite hydrogen container. The company's product portfolio extends beyond the drone itself to include a mobile hydrogen refueling station (truck-mounted), hydrogen fuel cell systems for small mobility vehicles (senior mobility, three-person family mobility, delivery bikes), stationary hydrogen generators, R&D services, and education/training programs, supported by labs in Yokohama, Fukushima, and Chigasaki plus a sales satellite in Shibuya, Tokyo.

The company's underlying technology is a proprietary hydrogen energy stack centered on a PEMFC fuel cell with standardized tank interfaces, enabling reuse across drones, mobility vehicles, and generators. Robodex monetizes through direct B2B and B2G hardware sales, managed hydrogen supply services via mobile refueling, professional R&D and joint development engagements, and training programs. Its primary customer segments are Japanese local governments (for remote island logistics, disaster response, and infrastructure), enterprise inspection/security operators, and logistics companies. The company emphasizes fully domestic Japanese production as a security and supply-chain differentiator and operates with the only set of hydrogen-handling permits in the country, giving it regulatory exclusivity in hydrogen drone deployment.

Robodex pursues an enterprise and government field sales motion supplemented by event-driven lead generation at industry trade shows (Japan Drone Expo, H2 & FC EXPO), with pricing conducted on a quote basis. Recent commercial activity has accelerated materially in 2026, including partnerships with TEPCO HD (next-generation drone), JAXA and Noshiro City (BOG hydrogen utilization), Tokyu Land (Hiroshima drone port), and multiple mobility OEMs, alongside deployment of Ansys Twin Builder for digital-twin-based design verification.

Scale indicators3 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Toyota Motor Corporation: Japanese automotive leader with deep hydrogen fuel cell technology (Mirai, fuel cell trucks, stationary generators). Comparable hydrogen ecosystem ambition across mobility and stationary power; potential customer, partner, or competitor depending on strategy direction in small mobility and drones.
• DJI: Global dominant drone manufacturer offering the Matrice series for enterprise inspection and surveillance. Sets the competitive baseline Robodex must beat on unit economics, even where hydrogen offers performance advantages; could enter hydrogen space with significantly greater R&D resources.
• Skydio: US-based enterprise drone leader focused on autonomous inspection and public safety applications. Comparable enterprise/government customer profile and inspection use cases; battery-electric today but with R&D depth to compete in hydrogen if the market develops.

Direct peers

• HevenDrones: US-based hydrogen drone startup developing stabilized hydrogen fuel cell UAVs for commercial and defense applications. Comparable product architecture to Robodex's aigis one and a direct competitor in the global hydrogen drone market.
• Doosan Mobility Innovation: South Korea-based developer and manufacturer of hydrogen fuel cell drones (DT30 and DS30 models) targeting commercial, public safety, and industrial inspection use cases. Direct head-to-head competitor to Robodex in the hydrogen drone category with global reach and significantly greater scale.
• EnergyOr Technologies: Canadian developer of hydrogen fuel cell powered UAVs with extended flight times for commercial and defense surveillance applications. Direct peer in hydrogen UAV technology with similar value proposition of multi-hour endurance vs battery alternatives.

Emerging players

• Wingcopter: German eVTOL fixed-wing delivery drone company that has explored hydrogen propulsion for long-range delivery. Comparable in target use case (remote logistics and last-mile delivery) and adjacent in hydrogen propulsion strategy, though primarily battery-electric.
• Micro Multi Copter (MMC): Japanese small drone developer (now part of ACSL group ecosystem) focused on industrial inspection and surveying. Comparable in Japan-domestic drone positioning and industrial inspection use case, though battery-electric rather than hydrogen.
• Equos Research: Japanese drone startup developing hydrogen fuel cell drones for surveying and inspection use cases. Direct Japan-market competitor with similar regulatory navigation challenges and comparable technology positioning.

Others

• Ballard Power Systems: Global hydrogen fuel cell manufacturer whose PEMFC technology is the underlying platform for hydrogen drones including Robodex's aigis one. Functions as both a potential supplier and indirect competitor should Ballard enter drone fuel cell stacks directly.
