In theory, one of the main applications RobotsHe should It works in environments (for any reason) very dangerous for humans. I say “in theory” because in practice, it is difficult to obtain robots to do useful things in semi -organized or unorganized environments without direct human supervision. That is why there is some recent focus Teleperration: Human software that collaborates with robots can be a very effective mixture.
In order for this mixture to work, you need two things. First, an intuitive control system allows the user to embody himself in the robot to effectively experiment. Secondly, a robot can fulfill a kind of embodiment that the human pilot needs. The second part is more challenging, because humans have very high criteria for mobility, strength and ingenuity. But researchers are in Italian Institute of Technology(( IitYou have a system that can examine both squares, thanks to the strong strong quadruple, which is now characterized by a pair of huge weapons on his head.
“The primary goal of this project, which was conducted in cooperation with InapHe explains “the expansion of human capabilities to the robot, allowing operators to perform complex tasks remotely in dangerous and unorganized environments to relieve their safety by exploiting the robot capabilities.” Claudio SiminiWhich leads ROBOT Telepierivo Project in IIT. The project depends on hygreal Hydraulic quadrantThe latest addition to the Quartet IIT family.
Hydraulic She was It is very clear that the fall is not valid in RobotsBecause they are complicated and chaotic, and in general the robots do not need to be tampered with Energy density Which comes with hydraulic. But there are still a few robots in active development that specifically uses hydraulics due to all this strength. If your robot needs to be very dynamic or really lift heavy things, then hydraulics are, at least at the present time, where there is.
Iit’s hygreal quadruped It is one of those robots. If you need something that can carry a large load, like a pair of huge weapons, this is your robot. Once again in 2019, We saw Hyqreal pulling a three ton plane. Hyqreal weighs 140 kg, and its knee joints can produce up to 300 meters of torque. The hydraulic system is operated on the plane Batteries It can provide up to 4 kilowatts of power. It also uses some of the beautiful mouth Integrated smart enginesUnfortunately, it does not seem to be in development anymore. Besides just lifting heavy objects, it makes the Hyqreal mass and its strength is a very stable platform, ensuring the durability of aluminum coils and skin durability.
Hyqreal is linked for energy during IIT experiments, but it can also work on battery power.Iit
Hyqreal weapons Iit-inail armsWhich weighs 10 kg each and has a 5 -kg load per arm. To put this in its correct perspective, the maximum load of A. Boston Dynami spot The robot is only 14 kg. The composition installed on the head of the weapons means that it can reach the ground, and it also has an overlapping work space to enable it Bilateral manipulation,, Which are enhanced by the ability of Hyqreal to move its body to help weapons within them. “The development of basic operating technologies with high energy, low weight and advanced control was a major empowerment factor in our efforts,” he says. Nikos Tasharakishead HHCM Laboratory in IIT. “These technologies have allowed us to realize the low -weight manipulation system with high -load -loads and a large work space, suitable for integration with hygreal. “
It is important to increase the accessible space, because the robot will be under Remote control For a person, who may have no special interest in mechanical or strong restrictions – they just want to accomplish the task.

To accomplish the task, IIT has developed a distance system, which is strange because it features a very large work space that allows the user to take advantage of the full -action group of robot. After trying a handful of different Remote attendance Systems, I can emphasize how important this is: It is very disturbing to do some tasks through Remote attendanceThen press the detailed on the robot and having to stop to reset your arm. This is why it is important to study the quality of experience in operators. It allows us to design HAPTIC and Telepertation systems appropriately because it provides an insight into joy or frustration associated with overwhelming perception, Happy Reactionsand Robot controlAnd the performance of the mission, “confirms Ioannis sarakoglouHe is responsible for developing telephone ventilation techniques at the HHCM Laboratory. Everything happens completely immersed VR The environment, of course, with some improvement of the intelligent reinforcement range inspired by the way people see that only high -precision images are transmitted as the user searches.
The remote attendance control system provides Hyqreal HAPTIC notes and a large business space.Iit
The system is designed to be used in dangerous environments where you don’t want to send a person. For this reason IIT partner in this project InapThe National Institute of Italy for Accidents Insurance, and is fully interested in finding ways in which robots can be used to remove humans by harm.
In tests with Italian Firefighters In 2022 (using a previous robot version with one arm), operators were able to use the system to extinguish the simulator tunnel fire. It is a good first step, but Semini has plans to push the system to deal with “the most complex, heavy and demanding tasks, which will better show its capabilities for real world applications.”
As always with robots and applications in the real world, there is still a lot of work to do, Simini says. “The reliability and durability of systems must be improved in harsh environments,” he says. “For example, the robot should withstand an intense heat and a long -term exposure to firefighting without prejudice to its operating performance or its structural safety.” There is also a robot energy consumption management (which is not small) to give it a useful time operation, and to manage the amount of information provided to the operator to enhance Circumstantial awareness While things still keep simplified and effective. “It increases the burden of perception, while there is a very little pregnancy that operators who have a lot of information can lead to a lot of information, while very little can To lead to errors and reduce circumstantial awareness. ” It leads the development of the overwhelming interface. “Progress in the front facades of the mixed reality and the components of the multimedia, such as Vocal orders and TraceIt is expected to improve efficiency and reduce future fatigue. “
There is a lot of intersection here with goals Darpa Robotics Challenge to Human robotsWith the exception of the IIT system, it can be said that it can be spread more realistic than any of these human beings, at least in the short term. Although we have just started seeing the capabilities of human beings in the environment that is carefully controlled, the cadres have already come out in the world, proving the extent of reliability that transported them in four legs. Tampering is the next clear step, but it should be more than just opening the doors. We need it to use tools, lift the debris, and all that other DARPA Robotics challenge Things that keep humans safe. This is what Telepierivo robot Trying to make real.
