The Robot RHex project at the University of Pennsylvania began about 15 years ago when researchers at several universities began to demand how robots could travel across rugged terrain and behave like animals. The microfiltration machine is a screen filter that intercepts fine suspended solids. It has a drum-shaped metal frame. The drum rotates around a horizontal axis and is supported by a braided stainless steel wire (or copper wire or chemical fiber wire). Network and work network. It can be used for filtration of raw water in water plants and removal of algae, water fleas and other plankton. It can also be used for filtration of industrial water, recovery of swimming substances in industrial wastewater, and final treatment of sewage.

Unlike wheeled, legged robots, they have animal-like capabilities to overcome obstacles such as stairs and reefs. But until the latest RHex, Aaron Johnson and Ph.D. student of development engineering professor Daniel Kodtschek, leg-robots cannot negotiate the gap in terrain over robots with wheels. 
Johnson has developed mechanisms to allow robots to jump past gaps and loopholes that it had previously plunged into. The tall convex usually blocks the path of the robot, and RHex can handle more than four times its own height on the platform.
Koditschek and Johnson designed the latest version of RHex using lightweight carbon fiber. This allows it to perform its functions without consuming much power for jumping and climbing.
