RT Journal Article T1 Hygrobot: Hydrogen-Powered Mobile Robotic Platform for Rough Terrain: Electro-Mechanical Design, Physical Implementation, and Experimental Testing A1 Delgado Asencio, Cirilo A1 Segura Manzano, Francisca A1 Andújar Márquez, José Manuel AB This work presents the electro-mechanical design, physical implementation,and experimental testing of an intermediate-sized mobile robotic platform, Hygrobot,which is powered by the hybridization of a PEMFC fuel cell and LiPo batteries. Futuremobile robots are anticipated to require sustainable and cost-effective energy solutionsto increase their working time and adhere to ecological guidelines. Although substantialadvancements have been achieved in creating marketable mobile robot designs, includingimprovements to their physical composition, sensory systems, navigation algorithms, andoperational management, their widespread integration is still hindered. This obstacle ismainly attributable to the lack of robust power systems capable of functioning in varied andoften unpredictable settings. Hydrogen, as an energy carrier, offers a promising solution toovercome these obstacles. Experimental tests reveal that the Hygrobot platform can achievea linear speed of 17 km/h, a continuous operating time of over 8 h, and power consumptionbelow 324WA. Its mechanical design means that Hygrobot is able to overcome obstacles,facilitating movement in the three XYZ axes, and can perform tasks over rough terrainefficiently.
