New shape memory polymer

The University of Rochester researchers have succeeded in creating a completely new polymer that can play an important role in the future in the field of medical applications. The new material has the ability to preserve its shape, but it can also return to its original shape, and the process is activated only by body temperature.

Memory-form materials are not uncommon today, are used in various industries and can be found in sleeping mattresses or headphones. Such material has been developed by scientists from the University of Rochester, but their invention is somewhat more advanced.

The new polymer created by the researchers has quite unusual properties. It can be tampered with, giving a new shape that will be preserved by him. Just touch it to the body, and then the heat will make the material return to its original shape. This is not important, but the fact that it returns huge amounts of stored energy when it returns to its original shape.

There are really many and experiments have shown that at this time the polymer can lift a mass 1000 times its own weight. During one of the tests, a shoelace sized piece was able to carry a liter bottle of water.…

ESA tests the printed antenna to the satellite

3D printing technology makes it possible to produce items that are much more accurate than traditional methods of making them. In addition, the production of more complex objects is much easier, not to mention the lower cost of their production. That is why 3D printers are increasingly being used in the space industry.

The European Space Agency plans to use it to produce components that will significantly improve the process of building satellites in the future and will reduce their costs. Currently in the Dutch Compact Antenna Test Facility in Noordwijk, testing of the first component from a 3D printer is under way, with a new radio antenna, providing satellite communication with the command center.

The antenna, despite its complex geometry, can be printed out in its entirety, eliminating the need for subsequent assembly. Moreover, this also eliminates the potential risk of later problems that may be related to inaccurate assembly of all components.…

Ford cars tested by robots

In 2013, the American company Ford announced the creation of a robot that was designed to test new vehicles and test their behavior in all driving conditions. After two years of construction, it is getting closer to completion, and Autonomous Solutions, Inc. is helping to create it.

Every new model car must go through exhaustive, multi-month tests before it goes into production, in which the vehicle is tested under various road conditions, in burning heat and high temperatures, on slippery and dry surfaces, In other words, you need to make sure that all of its components work properly, will not break down when you leave the living room, and will also manage the slippery road, that is simply eliminating all the weak points.

Nowadays this task is handled by factory drivers, but maybe in a few years, they will replace their robots. Ford engineers, along with Autonomous Solutions, Inc., are designing such a test-driven vehicle to simulate years of use in the real world.

The machine that replaces a human will be able to perform tests without interruption and to do so much more accurately, which during long-term tests of new models will certainly be a much cheaper solution than test drivers.

The test performed by the machine will simulate normal use of the car, and as the Ford engineers say, a few months’ test will be a simulation of a 10-year vehicle operation under standard conditions. This will allow you to assess the life of components and make the necessary adjustments to your car’s design.

The developed robot controls the car in the same way as a man does, ie, turns the steering wheel, uses accelerator pedal, brake and clutch pedal as well as gear lever. With special software, the machine will be able to perform specific tasks by repeating the desired number of steps.…
