Tiny robots harness surface tension to move and manipulate objects.
The researchers have created a robotic version of these beetles, which can move and manipulate objects using the same principle.
Introduction
The world of robotics has seen significant advancements in recent years, with researchers pushing the boundaries of what is possible with tiny machines. One area of focus has been the development of robots that can perform industrial tasks, such as assembly, inspection, and material handling. In a breakthrough study, Harvard University researchers have successfully created tiny robots that can exploit the Marangoni effect, a phenomenon where a surface tension gradient drives fluid flow.
The Marangoni Effect
The Marangoni effect is a well-known phenomenon in physics, where a surface tension gradient can cause a flow of fluid. This effect is commonly observed in nature, such as in the movement of water on a surface or the flow of air in a leaf. In the context of robotics, the Marangoni effect has been harnessed to create robots that can move and manipulate objects using a surface tension gradient.
How it Works
The Marangoni effect is driven by the difference in surface tension between two adjacent surfaces. When a surface tension gradient is created, it causes a flow of fluid from the area of higher surface tension to the area of lower surface tension. This flow can be harnessed to create movement and manipulation of objects. The researchers used a combination of materials and design to create a robotic version of the Stenus beetle, which exploits the Marangoni effect. The robot consists of a small, flexible body with a surface tension gradient created by a thin layer of liquid.
The Marangoni effect is observed in various natural and industrial processes, including the formation of droplets, the spreading of liquids on surfaces, and the movement of fluids in microfluidic devices.
Understanding the Marangoni Effect
The Marangoni effect is named after the Italian physicist Augusto Marangoni, who first described it in the late 19th century. The phenomenon is characterized by the movement of a fluid due to the difference in surface tension between two phases. This movement can be caused by various factors, including temperature, humidity, and the presence of surfactants.
Factors Influencing the Marangoni Effect
Several factors can influence the Marangoni effect, including:
The robots were able to move at a speed of 6 centimeters per second, but the soap was able to move at a speed of 1 centimeter per second. The soap was able to move at a speed of 1 centimeter per second, but the alcohol was able to move at a speed of 6 centimeters per second. The soap was able to move at a time of 1 centimeter per second, but the alcohol was able to move at a time of 6 centimeters per second.
The motor uses a combination of surface tension and viscous forces to generate motion. The researchers used a combination of surface tension and viscous forces to generate motion.
