Innovators from South Korea’s Hanyang University unveiled ‘SPIRA’ in June 2023, a novel delivery robot designed for sandy, grassy and paved road terrains.
Published in the International Journal of Precision Engineering and Manufacturing, SPIRA features a retractable spiral wheel mechanism.
This mechanism enhances mobility on beaches, dunes, and deserts, outperforming conventional wheels in these environments.
Additionally, SPIRA’s adjustable wheelbase stabilises it on uneven grassy landscapes, and it can switch to circular wheels for paved roads.
