According to media reports, the functions of robots are increasing. Nakajima, an associate professor at the Tokyo Institute of Technology in Japan, developed anthropomorphic robots that can swim automatically without external operations. The robot can swim forward and forth like a human freestyle. It is expected to play a role in analysing faster swimming movements and developing competition swimwear for Olympic athletes.
According to reports, the swimming robot developed this time is called "SWUMANOID", which is 89 cm tall and about half of human. Weighing about 7 kilograms, it faithfully reproduces the shape of the swimmer. "SWUMANOID" is made of resin and has 20 waterproof motors that adjust the number and position of the body's pendants to maintain balance while swimming. In addition to freestyle, you can also swim in the butterfly and backstroke.
It is reported that the researchers put "SWUMANOID" in the swimming pool and let them try freestyle in places where water does not flow. "SWUMANOID" advanced about 8.5 meters after swinging 20 times on both wrists. The speed is about 0.23 meters per second, and it takes about 108 seconds to swim in a 25-meter swimming pool. If the robot's body is equal to humans, you can swim to the end in half the time.
Researchers believe that this robot can be used not only for the analysis of swimming movements, but also for people who are not good at swimming. In addition, it is expected to be applied to the rescue of drowning people.
The wire rope is a helical wire bundle made of steel wires with mechanical properties and geometric dimensions that meet the requirements. The wire rope is composed of steel wire, rope core and grease. A steel wire rope is a rope that is twisted into strands from multiple layers of steel wires, and then a certain number of strands are twisted into a spiral shape with the core as the center. In material handling machinery, it is used for lifting, traction, tensioning and carrying. The steel wire rope has high strength, light weight, stable work, not easy to break the whole rope suddenly, and reliable work. In 1834, European Olubert invented the world's first steel wire rope (smooth steel wire rope).
Wire ropes can be classified according to the material, surface condition, twisting method and purpose of the wire rope.
Classified by material
1. Carbon steel wire rope is made by twisting high-quality carbon structural steel wire as raw material.
2. Stainless steel wire rope, manufactured and twisted with stainless steel wire as raw material.
