Robot with square wheels walking on the ceiling Bashny.Net

Lizards are a family of geckos on their feet "sucker" nano-scale, which allows them to move around the vertical and upper horizontal surface. Scientists have used this feature to create an adhesive tape and her robot equipped with square wheels: independent small device able to move the walls and ceiling.





Nature development long before man first came up with robots various nanotechnology and bring them into the process of evolution to a simultaneous extreme complexity and simplicity. Lizard gecko family inhabits the earth more than fifty million years, it surprised our ancestors the ability to move quickly on the vertical and top horizontal plane using a unique nanostructure foot.

High resolution microscopy in the early 21st century has proved that the basis sverhlipuchesti fingers gecko - vandervaalsed force mezhkolekulyarnogo interaction. On the fingertips of lizards - bristles, each of which has hundreds of flexible hair around a hundred nanometers in diameter. Tips of the hairs have a triangular spatula-suckers, which are arranged under the surface.

This technology has potential in robotics. Experts from the private research Case Western Reserve University in Cleveland developed a robot that can walk on walls and ceilings. They used a микроструктурированную adhesive tape for movement and body printed on 3D-printer. The robot uses a flexible feet-tape fixed on square wheels. Per square centimeter of tape poliviniksiloksana fit twenty ten thousand microscopic mushroom hooks.

In the future, this technology can be used to test the robotic legs for other devices.
