At Washington University, they have created a small flying robot which is reminiscent of a fly. Its dimensions are no bigger than 1-2 cm. The peculiarity of the device is that it does not need wires or batteries. The wireless power source is a laser that is directed to the photocell built into the robot's circuits and converts light radiation into 240 volts, which is more than enough for it to operate. The robot has two wings that rotate at a speed approximately equal to the speed of a fly's wings. Because of this, the robot can be entrusted with serious tasks: observation of animals and insects in the air, exploration of hard-to-reach places, and even rescue operations after landslides and floods. In the future, scientists plan to improve the operation of the laser to make the robot fly more agile and be more maneuverable.
Starting in 2019, the Bank of Tokyo-Mitsubishi UFJ plans to conduct tests of its cryptocurrency. About 100,000 respondents expressed an interest in the cryptocurrency of the Mitsubishi UFJ Financial Group (MUFG). At the moment, the bank's clients have already been given the opportunity to sign a document to convert part of their assets to the Mitsubishi UFJ Financial Group coin. The cost of this new coin is currently 1 coin equal to 1 Yen. Project participants will pay with these coins in various shops, restaurants, and pay for air tickets at a discount. They can also transfer their coins to other users. MUFG has already conducted preliminary tests over the past year with the participation of bank employees. In the future, MUFG plans to introduce ATM's that will allow bank customers to easily exchange their currency into the coin and back.
In China, individual provinces will be able to allow tests of autonomous vehicles on their territory. Earlier, the Chinese company Baidu received approval from the authorities in Beijing. Now, the company can obtain permmision locally after having already conducted testing under limited conditions. In addition, unmanned vehicles will be allowed to operate in the city on the condition that an experienced driver, with at least three years of experience, will be driving. The whole process of testing on city roads must be recorded and stored. All of this was done for the safety of urban residents in light of the frequent unmanned vehicle crashes involving people.
