Researchers at Tehran University, in Iran, unveiled last month an adult-sized humanoid robot called Surena 2. The initial press reports in Iran's official news media didn't include many details, saying only it could "walk like a human being but at a slower pace" and perform some other tasks, and there were questions about the robot's real capabilities. IEEE Spectrum obtained more information about Surena, as well as images and videos showing that the robot can indeed walk -- and even stand on one leg.
Aghil Yousefi-Koma, a professor of engineering at the University of Tehran who lead the Surena project, tells me that the goal is to explore "both theoretical and experimental aspects of bipedal locomotion." The humanoid relies on gyroscopes and accelerometers to remain in balance and move its legs, still very slowly, but Yousefi-Koma says his team is developing a "feedback control system that provides dynamic balance, yielding a much more human-like motion."
Surena 2, which weighs in at 45 kilograms and is 1.45 meter high, has a total of 22 degrees of freedom: each leg has 6 DOF, each arm 4 DOF, and the head 2 DOF. An operator uses a remote control to make the robot walk and move its arms and head. The robot can also bow. Watch:
