 Abstract, this paper examines the locomotion efficiency of surface micro rollers with varying diameters, 5, 10, 25, and 50 micrometers. Computational fluid dynamics simulations were used to predict the lift forces generated by the roller, but these predictions did not match the actual balancing forces required to maintain equilibrium. The authors hypothesized that there exists an additional force component in the direction of lift, which was not accounted for in the simulations. These findings have important implications for future applications in biomedical engineering. This article was authored by Yuga Bozouyuk, Hakankan Osterk, and Mutton City.
