 Liquid metal tendons give robots the ability to heal themselves In Japan, robotics researchers from the University of Tokyo's JSK Laboratory have created a prototype robotic leg with a metal tendon that can repair fractures. The not-so-distant future where robots can heal themselves doesn't seem like a fantasy anymore. The not-so-distant future where robots can heal themselves doesn't seem like a fantasy anymore. How does it do this? Simply by melting itself and then changing itself into a single piece. The work was presented at the recent IEEE/RSJ 2019 International Conference on Intelligent Robots and Systems. The researchers who developed a special metal tendon for the robot from Japan say that the self-healing module consists of two halves connected via magnets and springs. Each module half is filled with an alloy that has a low melting point of just 50 degrees Celsius. When the fuse is blown, the cartridges melt the alloy and allow the two halves to fuse together. Alt...

 Beat the chef, the robot can make 300 pizzas per hour A pizza maker robot that can make and bake 300 pizzas per hour with minimal human assistance was unveiled at the Consumer Electronics Show 2020. At the Consumer Electronics Show 2020, an American startup named Picnic (based in Seattle) introduced a rapid automated pizza making system with minimal human interaction. This system consists of 3 compact modular boards assembled to form a conveyor belt, capable of pumping ketchup, spreading cheese and placing sausages. Then, the robotic arm will bring the newly formed cake into the oven. The pizza is made with little or no human help. At full capacity, the robot can make 300 12-inch-diameter pizzas per hour. According to CEO Clayton Wood, the robot's pizza production speed will quickly beat the traditional pizzeria, which can only produce about 250 pieces per day. In terms of quality, Picnic wanted CES attendees to know exactly what pizza was made by a robot, so he made a "confe...

 Researchers announce "immortal" flexible lithium ion battery, promising to be available within the next 2 years Concrete builds the foundation of today's modern world, but what drives the technology of the future on top of that concrete are lithium-ion batteries. Battery technology is the lifeblood of most rechargeable electric devices, from the phone that fits in the palm of your hand to the electric car your family sits in. However, lithium-ion batteries are like concrete - they are the wild offspring of nature shaped by human hands, filled with unsolvable problems. Lithium-ion battery technology is based on toxic and flammable materials, so with just a little damage, any electrical device, no matter how small, will turn into a bomb with quite a bit of destructive power. However, we believe that science just hasn't found a safe solution yet. This type of battery remains safe even if it is cut or bent. This type of battery remains safe even if it is cut or bent.

 The US makes military uniforms capable of destroying nerve agents in a few minutes Scientists are working with the US military to develop clothing that can quickly destroy toxic substances, a measure intended to protect soldiers from . Inside the laboratory of chemist Omar Farha at Northwestern University, he and his colleagues are working on a special project, with the support of the US Army. They mix a powder and liquid into a paste with paint-like properties, dip cotton cloths in it, and then dry it. Through this process, the cloth can quickly neutralize the toxins of many dangerous chemicals, which can affect the human nervous system. This fabric is the latest success in the 10-year history of developing uniforms that can protect the wearer against chemical weapons, with destructive and somanic capabilities, also known as GD - a form of "grandmother". child" but more dangerous. These compounds have the ability to destroy the human central nervous system, blocking th...

 Scientists have just created a half-robot jellyfish Jellyfish usually swim about 1.2 m/min, but in experiments, cyborg jellyfish increased their speed almost three times. The electrical pulses make the jellyfish's body pulse faster, thereby increasing swimming speed. Scientists in California have created what seems to only exist in Hollywood movies: cyborg jellyfish. The strange, half-jellyfish, half-robot creature can swim nearly three times faster than ordinary jellyfish. Engineers at Stanford University and Caltech say this jellyfish helps people expand their understanding of the deep seas. But these biorobots also raise many ethical questions alongside their potential. “We try to make the most of natural biology and incorporate the best we can,” said John Dabiri, a longtime Professor of Aeronautics and Mechanical Engineering at Caltech University. know. Jellyfish are primitive invertebrates that have barely changed in the last 500 million years. (Image: Getty). "Jellyfish...

Programmer From A To Z Happy New Year of the Ox, at the beginning of the new year, I would like to share some fun concepts with you about programming. These concepts are drawn from my more than a decade of working as a programmer. Hope the article can bring you some joy in the early spring days. The keywords are arranged in order A-Z according to personal opinion, the information is for sharing experience and is for reference information with fellow programmers. A. Automation - Automate work. My idol in the IT world is Bill Gate, and my favorite quote from him is: "I choose a lazy person to do a hard job. Because a lazy person will find an easy way to do it. " What does the above quote and "automation" have to do with each other? Lazy people will always find clever ways to "automate" what happens every day. For example, programmers when performing command line programming to interact with data tables, we will repeat CRUD statements with each data table. If...

 4 Reasons Why Coder Needs to Compete in Programming? Have you ever thought that you should join any contest/challenge? Why should someone who has studied IT or even became a programmer still participate in contests/challenges regularly? Then here is the answer for you. 1. Help practice coding skills Unlike other professions, developers often practice more than theory. Code practice is very important so a developer should participate in regular contests/challenges by: Get to code new codes that I may never have met   Know how far your coding ability is   Learn more coding skills from others in the competition   Increase your own coding ability 2. Increase your ability to think creatively and manage time When developers participate in contests/challenges regularly, their thinking ability to solve problems will be faster than those who don't code less because: The cards in the competitions usually do not limit the creativity of the players. Each test will have many dif...

 6 Signs That You Code Bad! It may hurt to read this article, but don't worry too much. Everyone will experience some of these signs, but the important thing is that we are constantly working to improve it. If you don't know where you went wrong, how can you find a way to fix them right? Sometimes what we need is someone to point out our mistakes so that we can know how to fix them. We often know what we need to do to improve, but often refuse to do it. Always "for later", but "for later" sometimes means "Never". This is a typical sign of a lazy LTV and also a stepping stone to a bad LTV. Yesterday, I read a very long and valuable post by Daryll Santos on Github and will summarize some key and important information below, about 6 signs of a bad LTV. 1. Don't understand the purpose of the code Before writing code, you need to know what your code is for, what specific purpose it is. This is like running the previous code in your head. Signal: Kee...
