A new suction cup design relies on spinning water to grasp and climb rough and uneven surfaces.
While most suction cups can only secure to smooth surfaces, the water-based system designed by a team at Zhejiang University relies on zero-pressure difference (ZPD) technology to adhere to a wide range of surfaces. This technology improves the suction power of the system by incorporating a ring of water rotating at high speeds along the edges of the cups. This creates a powerful vacuum in the center of the cup without causing a large pressure differential on the edges, preventing leakage.
