EXXACT EXXACT ROBOTICS is the R&D and innovation center of the EXEL Industries group. One example of innovation is the TRAXX self-propelled straddle tractor, powered by a diesel engine. The company identified a need among its clients for solutions to reduce their carbon footprint in the face of growing environmental demands. Particularly in vineyards, where soil preservation and emission reductions have become priorities, making the electrification of agricultural machinery a necessity.
In this context, EXXACT ROBOTICS set itself a major challenge: to develop a cleaner, quieter version of an autonomous straddle carrier as a proof of concept. A machine capable of operating efficiently without increasing weight or compromising autonomy. To meet this challenge, the company called upon Kinell’s expertise, specialists in electrification and hydrogen technology integration.
Switching to an electric drivetrain required a minimum autonomy of 10 hours, while limiting weight to avoid soil compaction. The solution had to integrate a hydrogen fuel cell, high-pressure tanks (350 bars), and advanced energy management.
Using hydrogen involved enhanced safety requirements, especially for the storage and distribution of the gas under pressure. Kinell has worked with EXXACT ROBOTICS and standardization bodies to develop safety measures that go beyond existing standards.
EXXACT ROBOTICS launched the world’s first autonomous hydrogen-powered grape harvester concept, called TRAXX Concept H2. The capacity of its high-pressure tanks allows a full day of uninterrupted work.
For this project, Kinell developed a complete electrical architecture for TRAXX Concept H2, integrating the selection of batteries, motors, and electrotechnical components adapted to agricultural constraints. Each component was carefully chosen to maximize autonomy and energy efficiency while minimizing impact on the robot’s existing structure.
Kinell’s teams designed specific software to control energy distribution between the hydrogen fuel cell, batteries, and electric motors of TRAXX Concept H2. It ensures real-time optimization for smooth operation and controlled consumption.
Kinell’s teams modeled and integrated new components into the robot’s existing structure. Material strength calculations were carried out to ensure the structure can withstand new constraints without compromising durability.
Thanks to its expertise and strategic partnerships, Kinell selected trusted suppliers able to provide high-performance components essential for an emerging technology such as hydrogen. Real-condition testing was conducted to guarantee system robustness, including load simulations, energy efficiency checks, and thorough safety inspections.
