Hydrodynamic Effect Helps Motorized Objects Navigate Inclines

Scientists have uncovered how heavy, motorized objects climb steep slopes — a newly discovered mechanism that also mimics how rock climbers navigate inclines. The finding stems from a series of experiments in which motorized objects were placed in liquid and then moved up tilted surfaces. These “micro-swimmers” are about 20 times heavier than the fluid they swim in but they were able to climb almost vertical steep slopes.
