The Smilla H₂ autonomous rover, equipped with an electric power train incorporating a hydrogen fuel cell extender unit, was unveiled at the recent EIMA show in Italy. This advanced vehicle, a collaborative effort between Italian company Ecothea and the research group at Politecnico di Torino, signifies a step forward in autonomous technology. Designed as a multifunction platform vehicle, the Smilla H₂ boasts a 400kg payload capacity and a modular design that enhances versatility. The hydrogen fuel cell onboard the rover powers a generator responsible for recharging a Li-ion battery pack, enabling prolonged operation and improved efficiency. The collaboration between Ecothea and Politecnico di Torino illustrates the synergy between industry and academia in driving innovation. By harnessing hydrogen fuel cell technology, the Smilla H₂ showcases the feasibility of integrating sustainable power sources in autonomous vehicles. The presentation of this cutting-edge rover at the EIMA show highlights the potential for hydrogen to revolutionize the field of autonomous applications. With a focus on functionality and eco-friendliness, this project sets a new standard for multifunction robots in various operational scenarios.
