Recently, Iranian robot experts have developed a humanoid robot Surena IV, which can grasp a water bottle and write. It is known as the most advanced humanoid robot in history.
Surena IV is 1.7m high and weighs 68kg. It is the fourth generation product iterated on the basis of the humanoid robot Surena. It adds imitation function and makes limb movement more flexible.
In terms of overall design, Surena IV is very similar to Honda’s asimo robot. Its whole body has 43 degrees of freedom. It can manipulate various objects by hand and even operate electric tools.
1、 Can operate electric tools and walk freely on rough roads
More than 50 researchers from the center for advanced systems and Technology (CAST) of Tehran University formed a special research team. Under the leadership of aghil YOUSEFI KOMA, a professor of mechanical engineering, it took four years to develop Surena IV.
Aghil YOUSEFI KOMA said that improving the interaction between robots and the environment is one of the main objectives of their Surena IV project. “Surena IV can now accurately track objects and has high flexibility in motion. It can not only pick up water bottles, but also manipulate all kinds of objects, including power tools,” he said
The researchers said that Surena IV is also very flexible in walking. Its custom force sensor on the soles of both feet can adjust the angle and position of each foot landing, and can walk freely even through uneven roads.
The walking speed of Surena IV has also been greatly improved, from 0.3km/h of the first generation to 0.7km/h.
Although Surena IV is not a high dynamic robot like atlas, it can’t do gymnastics or “spin jump”. However, the balance ability of Surena IV can not be underestimated. It can constantly adjust its posture and avoid falling by relying on the motion controller of the whole body.
In addition to the upgrading of the internal structure, the appearance of Surena IV also adopts a new plastic shell to make the appearance of the robot more safe.
2、 43 degrees of freedom, including climbing, playing football and writing
In 2008, researchers at Tehran University in Iran developed a humanoid robot called Surena. At that time, Surena’s function was very simple and even could only move on wheels. Soon after, the research team launched Surena II, which was upgraded based on the basic functions of Surena to make it capable of walking.
In 2015, the research team of Tehran University upgraded Surena II and launched Surena III. Compared with its previous products, Surena III is very advanced. It can not only go up and down stairs, but also play football.
Recently, Iranian robot experts introduced Surena IV to the world. This time, the function of Surena IV is more powerful.
In terms of sports ability, it has a total of 43 degrees of freedom, which can support it to complete the actions of shaking hands, bowing, climbing stairs, kicking football, writing and so on. In terms of interaction ability, Surena IV can convert the entered text into voice playback and imitate human actions.
Since the first version came out in 2008, Surena has gone through a process of more than ten years, from the first generation of products with only 8 degrees of freedom and can only move with wheels, to Surena II with walking ability, and then Surena III with 31 degrees of freedom and can play football. Aghil YOUSEFI KOMA said that today, Surena IV’s motor ability and interaction ability have reached the top level in the world.
3、 Surena IV inspires more possibilities in Robotics
Aghil YOUSEFI KOMA once said, “I hope our team can make Surena IV more competitive, participate in international challenges and find users.”
In order to make Surena IV more widely known, Professor aghil YOUSEFI KOMA hopes to bring it to more international exhibitions. He also published several papers with the R & D team on biped motion of humanoid robots and other topics.
In December 2019, aghil YOUSEFI KOMA once exhibited the Surena IV robot. At that time, he asked Surena IV to hold a box with both hands. In the box, the cast team developed a robot Surena Mini about the height of an adult’s knee in 2017.
Professor aghil YOUSEFI KOMA said: “I see Surena IV as a symbol of the development of technology towards peaceful coexistence with mankind.” And expressed the hope that Surena IV can help people inspire more possibilities of robotics.
