Recently, Iranian robotics experts developed a humanoid robot Surena IV, can grasp the water bottle and write, known as the most advanced humanoid robot in history. The Surena IV, which weighs 1.7 meters and weighs 68 kilograms, is the fourth generation of products iterative on the basis of the humanoid robot Surena, with new imitation features and more flexible limb movements.
The Surena IV is very similar to Honda’s Asimo robot in the overall design, which has 43 degrees of freedom in its body, and can manipulate objects by hand, and even power tools.
First, will operate power tools, rugged road can also walk freely
More than 50 researchers from the Center for Advanced Systems and Technology (CAST) at the University of Tehran formed a dedicated research team that took four years to develop Surena IV, led by Aghil Yousefi-Koma, a professor of mechanical engineering.

Aghil Yousefi-Koma says improving robot interaction with the environment is one of their main goals for the Surena IV project. “Surena IV can now track objects accurately and has a high flexibility of motion, not only to pick up water bottles, but also to manipulate a variety of objects, including power tools,” he said. “
Surena IV is also very flexible, the researchers said, with custom force sensors on the soles of its feet adjusting the angle and position of each foot landing, even on uneven surfaces.
Surena IV’s walking speed has also improved significantly, from 0.3km/h to 0.7km/h in a generation.
Although Surena IV is not a high-dynamic robot like Atlas, it doesn’t do gymnastics or “spin jumps.” But surena IV’s balance is also not to be underestimated, it relies on the body’s motion controller, can constantly adjust posture, to avoid falls.
In addition to the interior structural upgrades, surena IV also features a new plastic housing to make the robot’s exterior look safer.
Two, 43 degrees of freedom, climbing, playing football, writing is not under the words
In 2008, researchers at the University of Tehran in Iran developed a humanoid robot called Surena, which was so simple that it could even be moved on wheels. Soon after, the team launched Surena II, which was upgraded to the basic functionality of Surena to be able to walk.
In 2015, a team at the University of Tehran upgraded Surena II to launch Surena III. Surena III is more advanced than its predecessors, not only up and down the stairs, but also football.
Recently, Iranian robotics experts introduced Surena IV to the world. This time, surena IV is even more powerful.
In terms of athletic ability, it has 43 degrees of freedom, which can support it to complete handshakes, bows, climbstairs, kick football, write and so on. In terms of interactivity, Surena IV converts the entered text into a voice playback and mimics human movements.
Since the first version came out in 2008, Surena has gone through more than a decade, from initially just eight degrees of freedom, a first-generation product that can only be moved on wheels, to surena II with walking ability, to Surena III, which has 31 degrees of freedom and can play football. To this day, Surena IV’s mobility and interactivity are at the top level in the world today, says Aghil Yousefi-Koma.
Third, Surena IV inspires more possibilities of robotics
Aghil Yousefi-Koma said: “I want our team to be more competitive with Surena IV, to take part in international challenges and find users from it.” “
To make Surena IV more widely known, Professor Aghil Yousefi-Koma hopes to bring it to more international exhibitions. He has also published several papers with the research and development team on humanoid robot bipedal motion and other topics.
In December 2019, Aghil Yousefi-Koma exhibited surena IV robots when he had his hands held up a box containing suremin, a robot that the CAST team had developed in 2017, about the height of an adult’s knee.
Professor Aghil Yousefi-Koma said: “I see Surena IV as a symbol of technology’s peaceful coexistence with humanity. And hope sure surena IV will help people inspire more possibilities for robotics.
