Jump from one platform to another, and then a back flip! A few days ago, a humanoid robot was perfected to play back and the video of the flip-flop spread on the Internet, making the humanoid robot Atlas a "net red". Named after the eternal power of Greek mythology and the support of the heavens, "Atlas" really lived up to expectations, realizing a beautiful backflip with the reinforced iron body, marking another leap in the field of robotics research. The existing "kingdom" of robots includes different "populations" such as fixed, wheeled, crawler, bipedal and multi-footed. The leg-foot robot, which is characterized by both feet and multiple feet, has stronger adaptability to the harsh terrain environment and is more difficult to develop, representing the technical peak in the field of robot research. For a long time, all military powers have shown strong interest in the study of leg-foot robots. The development of leg-foot robots such as "Atlas" is behind the huge demand for military applications. How hard is it to turn a somersault It’s not that the robot turns a “fighting fightâ€. How hard can it be? However, after the backflip is a very difficult action, it is not easy for ordinary people to do it, that is, the gymnast must also train for a long time to complete. The robot "Atlas", which entered the "gymnastics" field, is itself a large-scale biped robot with a "slimming body". In addition to maintaining balance during the movement, it is also necessary to balance the volume with legs. Upper body. In order to complete the seemingly impossible task of “back flipâ€, “Atlas†needs to move from hand to foot and waist at the same time. Its "brain" must accurately calculate the motion lines, directions and angles of each part through mathematical formulas, and then mechanically control the starting, turning and landing. All beginnings are hard. In terms of take-off, “Atlas†needs to plan the entire process ahead of time. More importantly, "Atlas" must have strong and powerful legs. If the power is not big enough, you can't leave enough time for the flip, let alone the subsequent dynamic adjustment. Atlas is now equipped with a built-in drive battery, and with effective power management, it can explode tremendously in an instant. In fact, the air flip process is the real "see kungfu" action. "Atlas" is a multi-degree-of-freedom, multi-rigid robotic system. The precise control of the attitude is extremely complicated. It requires various attitude sensors in the robot to return the status parameters in real time. By concentrating the posture information from various parts of the "body", its "sports center" can make control decisions according to the algorithm, and continuously optimize the parameter indicators of each part. The "Atlas" in the air is in a parabolic motion state, and it is necessary to change the posture to find the best posture of "debut" before landing. Even if all the way is "small", "Atlas" is too simple to imagine "safe landing". In the process of landing, it is necessary to deal with the impact treatment and balance. Regardless of the contact surface, Atlas will be subjected to huge contact impact at the moment of contact with the ground. At this time, the hydraulic servo control system is used to effectively reduce the instantaneous impact force. A multi-dimensional force sensor is also installed on the foot of Atlas to assist the force state of the foot. At the same time, the "joint" position of "Atlas" moved up or down a little at a time, which may cause the center of gravity to fall and fall, which puts higher requirements on precise control. "Men No. 1" shows new skills Speaking of military robots, our first reaction was a wheeled or crawler-type, clumsy machine equipped with robots and sensors. In the sci-fi movies of "Mechanical Enemy" and "Terminator", the robot has been portrayed as a "Steel Warrior" standing on both legs. Today, the leg-foot robot represented by the humanoid robot is embarking on a well-developed "fast lane", and "Atlas" is one of the best. Through continuous improvement and upgrade, “Atlas†can “walk†through various terrains, climb and pick up heavy objects, and the hand can complete the action of opening the door and grabbing objects. Through the Lidar and various sensors on the body, this guy also has the ability to avoid obstacles and identify objects. The researchers once asked "Atlas" to be "Golden Chicken Independent" on a 2 cm wide board, and it succeeded for more than 20 seconds. Nowadays, Atlas has unlocked new skills again, and in addition to achieving beautiful backflip, it has become more lightweight and smart. Even if the backflip falls and falls, it can climb up on its own. Before "Atlas" became "Net Red", there was also a leg-foot robot that caused widespread concern because it resembled "wooden cows", that is, the "big dog" robot. The real name of the "big dog" is the "Infantry Team Support System", which was jointly developed by Boston Dynamics and the US Department of Defense Advanced Research Projects Agency. The "big dog" weighs 109 kilograms, runs at speeds of 6.4 kilometers per hour, and has a maximum climb of 35 degrees. Rather than saying that "big dog" is a machine "dog", it is better to say that it is a machine "scorpion". The "big dog" mainly imitates the quadruped, transports materials on the battlefield with complex terrain, and can carry 30 kilometers on the rugged mountain road. However, the “big dogâ€, which looks good, was sent to the front line of Afghanistan. It was loud and invisible, and it was difficult to repair on the battlefield. It was not officially listed in the US combat troops. "Machine Warrior" will appear in the future battlefield As early as in the battlefields of Afghanistan and the battlefields in Iraq, the military robots of the US military have already shown their talents. However, these robots are mostly wheeled or crawler-type, with poor obstacles and poor terrain adaptability. Robots represented by "Atlas" can stand, walk and run, and it is possible to change the mode of future wars and stir up the entire battlefield. As early as the beginning of 2015, Russian President Vladimir Putin had visited the same "smart and smart" humanoid combat robot, which even could ride a motorcycle. These military robots that have the ability to perform reconnaissance surveillance, alert duty, and precision strikes, or will be thrilling robot battles in the future battlefield. In the future, the battlefield situation is complex and changeable. Robots such as “Atlas†can exert their mobility and flexibility in mountain combat and urban combat to achieve better combat results. The US Department of Defense-funded "Rise" robot has six mechanical legs driven by electric motors. It is not a problem to climb trees or overturn walls. The target is directed at special reconnaissance. Even the legged robots such as the "big dog" are not only a "coward" in the future, but also can be equipped with weapons and protective armor to become an infantry fire support platform to better coordinate human operations. In fact, it is a painstaking effort to develop "Atlas", and people are looking for a "iron armor" for themselves. The US Department of Defense has long used the same technology to develop "machine legs" that can be tied to soldiers' legs, also known as exoskeleton boosters. This kind of "machine leg" can greatly increase the weight of materials carried by individual soldiers, reduce the fatigue of long-term load, speed up the march, and transform each soldier into a "machine warrior." Through the "enlightenment" of the "Atlas" hand and foot activity, people will also develop a more magical "manipulator." At present, humanoid robots with robots have been able to enter hazardous environments and have broad application prospects in dealing with nuclear accidents and explosives. Of course, the "Astra's" road from "Atlas" is still full of thorns. In general, the energy consumption of a robot when it performs the same task is more than 100 times that of a human being, and its endurance has certain defects. In addition, the precise handling and balancing of robots is a technical problem that has not yet been fully solved and still needs to be improved and developed.
