Surena IV is an adult-size robot built by University of Tehran

A little more than a decade ago, researchers in the University of Tehran introduced Surena was named by a humanoid robot. A better version capable of walking, Surena II, has been declared not long afterwards, followed by the capable Surena III at 2015.

Now Surena IV has been unveiled by the roboticists. The robot is a significant advancement over previous designs. A movie reveals the robot grasping a water jar, mimicking a individual’s present, and writing its own name.

Directed by Dr. Aghil Yousefi-Koma, a professor of mechanical technologies, the team functioned for the previous four decades to build up the new robot.

“Enhancing the robot’s interaction with the environment was among the chief aims of this Surena IV job,” Professor Yousefi-Koma informs IEEE Spectrum. He clarifies that the robot is now able to monitor objects and it was given dexterity by palms. These improvements allow it function power tools, in addition to to control a variety such as ones that are fragile.

Surena IV is also nimble. By simply adjusting the angle and position of every foot custom made drive sensors on the base of its feet assist the robot measure over surfaces. Walking rate increased to 0.7 km per hour from 0.3 km/h in the former generation.

While Surena IV isn’t a exceptionally dynamic machine such as Atlas, the famously Loaded humanoid in Boston Dynamicsit depends on a whole-body movement controller which constantly corrects its position to prevent falls.

Surena IV comes with hands which let it grasp a variety of objects.

To create his robots widely known, Professor Yousefi-Koma has sought to carry them to global conventions and trade reveals , along with his team has released papers on humanoid robot layout , bipedal locomotion, along with other subjects . He’s stated that his team would like to”create [Surena] quite aggressive and might be participate in an global challenge in addition to discovering real users and applications ”

In footage published as part of Surena IV’s unveiling, that occurred late last year, the Ninja is revealed lifting a box, inside of which can be Surena Mini, a knee-high robot the CAST group developed in 2017.

Another video provides a look in Surena’s advancement, helping the robot since it takes its first steps, writing code, and revealing the investigators examining new hardware.

The development of Surena
The hottest Surena version has come a long way because the first version, introduced in 2008, which had just 8 degrees of freedom (DoF) and wheels that were used on its own feet to maneuver around. Surena III, together with 31 DoF, exhibited skills such as climbing steps and kicking a ball.

Surena IV has more axes of movement, with added 12 DoF, most on the palms, bringing the total to 43 DoF. The CAST team constructed elements, creating customized actuators that were small yet strong and new lightweight components.

Another advance is the controller of that the robot. A system enables the robot to recognize and create language that is fundamental.

To create all of the detectors, controllers, and actuators work collectively, the investigators equipped Surena using the Robot Operating System, or ROS. In addition they used Gazebo, Choreonoid, and MATLAB to mimic the robot’s moves and assess unique behaviours, such as walking backward and backward, turning round, and push retrieval.

However, the updates are not internal. The exterior of surena IV features vinyl covers which make the robot look slightly menacing — and slick. Professor Yousefi-Koma has highlighted that he perspectives Surena as a”sign of technology progress in the management of humanity and peace,” hoping it’s going to help inspire people about the options of robotics.
