Now when it comes to robots, it seems no one imagines footage from “Terminator”. People have learned to use robots for the good of society, and now under that definition, hiding not only humanoid machines, but also those who are simply able to automate one process or another. Huge industrial robots are used in mining enterprises, factories, car Assembly and household appliances, and small their counterparts settled in some house. But there is the most sophisticated robot on Earth? And if so, how it looks and works?
How to create the most complex robot
This robot was created nearly 7 years ago, and it is constantly developed, so far no one has managed to outdo. Agency for defense advanced research projects USA (DARPA) in conjunction with the company Boston Dynamics developed a humanoid robot called Atlas. He perfectly oriented in space and has 28 hydraulic joints, a multitude of sensors and advanced control system.
In Boston Dynamics say that initially, the robot was managed by the operator, in order to create a three-dimensional map of the area of movement. But then the humanoid was able to walk on his own already included in its database information about the environment and the obstacles.
At first, he really reminded minion of Skynet and could not move without connecting to a managed computer and power supply. Had a height of 190 centimeters and a weight of 136 kilograms. Just a couple of years it took the developers to release a new version of the robot Atlas, which was the most sophisticated robot on Earth. First, they updated its firmware, and then — and the “body”, making the robot more like a human.
New Atlas robot Boston Dynamics
Developers have added a humanoid robot battery capacity of 3.7 kWh, which can provide him with hours of battery life, including movement and some other actions. In addition, to compensate for the increased mass due to the installation of battery engineers had to use lighter materials when creating the hull Atlas. Also, the creators added in robot wireless module for communication and has improved its moving parts, increasing freedom of movement of humanoid. His height was reduced to 1.5 meter and a weight up to 75 pounds so it maneuvers easier to perform. Engineers wanted to make the robot as light as possible and durable, many did developed from scratch by developers from Boston Dynamics and is printed on a 3D printer. This more no one.
Since then, the creators of the robot are engaged in that improve the navigation system and teach it new moves that could potentially be useful to him when working in difficult conditions. So, in the past year, Atlas has learned to jump turn 360 degrees — just like a gymnast. How did he manage to do this?
Atlas is the only robot on Earth who can perform tricks with an accuracy of 80%.
How to construct the most complex robot
In addition to the 28 articulated joints, by which the Atlas moves his arms, legs, back and other parts of her body, the robot is also equipped with a variety of engines (the number is kept secret), which lead to its moving, receiving power from the internal battery. As the robot realizes that he, for example, need to step over the obstacle? For this he has stereo vision, lidar, gyroscopes, rangefinders, and other sensors that help him to navigate in space. All this information is fed back to the CPU is a very powerful chip, which sends a signal to the motors. And they already lead the robot to move. The work of the Atlas can be compared with the work of the human brain: if the human eye sees the danger, it sends this information to the brain, and from there the command is given, for example, to Dodge a case or step aside.
Atlas has one of the most compact mobile hydraulic systems in the world. Due to the special motors, valves and hydraulic power units, Atlas can supply the necessary power for any of its 28 hydraulic joints. That is why he is so fervently engaged in parkour, runs, tumbles — no other robot is not able to. And since no one produces analogues, Boston Dynamics had to do most of the components from scratch.
For several years, the robot provided an improved control system, thanks to which he knows a lot of moves. Planning every move he takes 0.5 seconds — during this time, the robot analyzes the space around them (with sensors), itself weighing (assessing whether there is enough power to lift body and overcome the obstacle) and takes a decision. Interestingly, the engineers managed to teach the robot to use your hands for balance of the body as well as people.
The maximum movement speed of the robot Atlas is 1.5 m/s or 5.4 km/h, which is comparable with the walking speed of the person.
Some in our Telegram chat it seemed that the robot has intelligence, but it is not. Its software was written by engineers who can control the robot with the macros (for example, to get it to run, Crouch, step, and so on). That is, it is either controlled by “remote”, or simply executes pre-programmed commands. The teams have already converted to microcastle and algorithms limbs to ensure these movements. Humanoid is controlled using the robotic operating system (ROS — Robotics Operating System). Most extensions written for it in programming languages C++ and Python. However, officially this information have not confirmed the Boston Dynamics keeps a lot of secrets. Still, it’s the most complex robot in the world.
Why do we need robots
Plans Boston Dynamics — add to the robot’s artificial intelligence, and there to the ability to respond to command to close. Of course, you can record a set of phrases and embed them, but it has some “innovations for the innovation”, so now there are even smart in your column. Here the proportions are quite different.
Now, for example, the robots Boston Dynamics help in the fight against coronavirus in the United States.
Originally Altas was created for rescue operations after man-made or natural disasters. For example, for the elimination of consequences after the tsunami and nuclear power plant explosion, as happened in 2011 in Japan. But every year its scope gets bigger, and who knows — maybe in 20 years these “Altay” will meet you at resuspen at the hotel. Or used as a replacement soldier in the army. Although… the first option is better.
