Scientists have developed a suction unit that can be used on rough surfaces, no matter how textured, and that has applications in the development of climbing #robots and robotic arms with grasping capabilities.

Researchers Xin Li and Kaige Shi developed a zero-pressure difference (ZPD) method to enhance the development of vacuum suction units. Their method overcame leakage limitations by using a high-speed rotating water ring between the surface and suction cup to maintain the vacuum.
