There is a new kind of speed bump that barely exists if your vehicle respects the speed limit, but hardens if you don’t. An entrepreneur from Málaga has developed this bump alongside the Badennova company. Inside there is a non-Newtonian liquid that, at slow speeds behaves like a liquid, but at high speeds hardens on impact to create a bump. It is being implemented in Spanish territory and every day there are more requests for it from countries such as the United States or Argentina.

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.
Elon Musk on Cameras vs LiDAR for Self Driving and Autonomous Cars
Опубликовано: 27 апр. 2019 г.Tesla and Elon Musk outline why they believe cameras (vs lidar) are all that is needed for Full Self Driving during the Tesla Autonomy Day for Investors on April 22, 2019. Elon also touches on why they don't consider HD Maps and precision lane markings to be
Elon Musk says lidar «is a fool’s errand» and that anyone using lidar is «doomed.» He goes on to say that they are «expensive sensors that are unnecessary. It’s like having a whole bunch of expensive appendices. Like, one appendix is bad, well now you have a whole bunch of them, it’s ridiculous, you’ll see.»
There quite a bit of debate in the self-driving world whether lidar is truly required for Full Self-Driving capabilities on autonomous vehicles. Lidar provides very a very accurate, high precision depth map of the world around the car, but is currently still fairly expensive and also has challenges seeing through occlusions, like rain, snow and fog. Tesla's argument is that roads were built for human drivers with vision and that vision systems, such as cameras will do a better job traversing that environment than other sensors, reading all the vision queues meant for drivers, like road signs, etc. In addition, Tesla believes their vision system (plus radar) accurately handles depth sensing problems and that lidar is not needed for that function.

Если имя Сатоши Накамото — создателя битка также как и его детище — на слуху, то о Виталике Бутерине, создателе нашумевшей платформы эфириум и криптовалюты эфир практически ничего не известно. Так кто же он, этот загадочный молодой человек, создавший в 19 лет платформу, сделавшую революцию в криптомире?
