Опубликовано: 26 мая 2020 г.Всего несколько веков назад Испания занимала огромную площадь и была одной из наиболее влиятельных стран в масштабах всей планеты. Расширив свои владения до самой Азии, она распоряжалась большими колониями, которые охранялись сильнейшей армией и флотом. И все это время под боком этой империи ютилась небольшая Португалия. Почему же эту страну так и не удалось захватить?

7 Rubik's Cube World Record Robots — Fastest & New Inventions
Опубликовано: 24 окт. 2019 г.On this list, we are going to see Rubik's Cube Robts which broke world records: fastest and the unique new inventions. We will explain how a self-solving Rubik's cube works and will also talk about the Open AI's robot hand that can solve the Rubik's cube and also will talk about the Gan Robot which is made for consumers and is powered by a smartphone.
1. Cubestomer 3 (made from LEGO)
Powered by Samsung Galaxy S4, CubeStormer 3 robot broke the Guinness World Record for solving a Rubik's cube in 3.253 seconds in 2014. The robot was built by Mike Dobson and David Gilday, creators of CubeStormer 1, Android Speedcuber and CubeStormer 2.
2. Paul Rose and Jay Flatland Rubik's Cube Robot
This Rubik’s cube solving robot was developed by two software developers Paul Rose and Jay Flatland. On February 5th, 2016, the machine broke the 2.39 seconds world record held by Zackary Gromko’s robot, by solving the cube in 0.9 seconds using. Four USB webcams are used to feed data into software running on a Linux PC that determines the cube-state and this, in turn, is relayed to the Kociemba Rubik's Cube solving algorithm. The algorithm then determines a set of moves to solve the Rubik's Cube and the instructions are sent to the stepper motors.
3. Sub1 Reloaded
Built by Infineon's engineer Albert Beer from Germany, The Sub1 Reloaded smashed the Guinness World Record by becoming the fastest robot to solve a Rubik's with just 0.637 seconds in November 2016. This breaks the previous record of 0.887 seconds achieved by an earlier version of the same machine using a different processor. While every Rubik's Cube can be solved with just 20 movements, Albert did not design the computer to use the fewest moves. Instead, he programmed it to achieve the best time, allowing the Sub1 Reloaded to take extra moves to reach its goal.
4. Rubik's Contraption
Currently, Rubik's Contraption is the fastest robot to solve Rubik’s cube. Developed by M.I.T’s graduate Ben Katz and Jared DiCarlo, the robot solved the Rubik’s cube in just 0.38 seconds in 2018. The robot is built from custom parts that are easily acquirable. It uses six Kollmorgen's ServoDisc U9-series motors, which can be obtained relatively cheaply on eBay, as well as optical encoders on the back, also from eBay. To detect the current state of the cube, a pair of Playstation 3 Eye webcams were positioned at opposite corners of the cube, allowing each camera to observe three faces. A special software was developed to identify all the colors, build a description of the cube and pass it to the min2phase solver which implements Kociemba's two-phase algorithm.
5. Dactyl — Robot Hand
Unlike other Rubik cube solving robots, this is a humanoid robotic hand is not designed specifically for solving Rubik’s cube. It is designed for general purpose, self-learning robots. It is called Dactyl. Developed by Artificial intelligence research organization OpenAI, Dactyl has learned to solve a Rubik’s cube one-handed. It is not as fast as those purpose-built Rubik’s solvers, because the robotics team at OpenAI has very different ambitions. They are trying to build something that is much more general in its scope, similar to how humans and how human hands can do a lot of things, not just a specific task.
6. A Self-Solving Rubik’s Cube
You might think that there are some camera tricks or visual effects in this video, well… you are not alone. Many people thought so too when the Japanese inventor, Human Controller posted this video on his youtube channel. This is a real Rubik’s Cube that can completely solve itself while floating in mid-air.
How does a self-solving Rubik's cube work?
With the help of the “first two layers” or the F2L algorithm, the Arduino board at the heart of the cube controls the 3D printed custom cores full of servo motors that spin any of its multi-colored sides. The levitation was made possible by installing powerful magnets in both the cube and the table under it.
7. GAN Robot
The GAN Robot can both scrambles and solves a 3x3 Rubik’s cube using a smartphone app. For now, it can only solve the GAN 356i cube. It can solve the cube in less than 15 seconds after calculating the best solving path in 0.01s. The robot is perfect for teaching people to solve the cube step by step, scrambling cubes uniformly in competitions for fair and accurate results.

Samsung Galaxy Fold Teardown! — How does it even work?
Опубликовано: 10 окт. 2019 г.The new Samsung Galaxy fold is pretty much the coolest phone on the market right now. Yeah, folding smartphones are new, and the folding technology is new, BUT the innovation possibilities with folding phones is fascinating. The Galaxy Fold had a rough start with phones breaking left and right. But Samsung seems to have gotten their act together this time around, and is offering replacement screens for 149 dollars if it happens to break within the first year. ($599 dollars if the Galaxy Fold breaks more than once, or happens after the first year.) Super awesome of Samsung to take care of their customers like that.
