When Boston Dynamics releases a new video of one or more of their robots doing something flashy, it’s usually hard to miss.But if you have been in trouble in the last few days, you might want to take a look Atlas Parkour Video. The last time we saw a pair of Atlas robots perform some dance moves with some other Boston dynamic robots, although this is an incredible display of the level of control they designed, they are actually just playing back a series of pre-programmed Actions. However, the obstacle course presentation seems to be different. There is a good overview of the presentation in IEEE Spectrum, and they pointed out that this is the first time we have seen Atlas demonstrate the use of all four limbs for coordinated movement at the same time-the sweet vault that spans the fence. Really, it’s hard not to see this kind of human-like action, and don’t think it’s just a person in a robot suit. Even tripping people feels very human.However, what’s more interesting is Behind the scenes of Atlas. Especially for facial plants and failures.
August 19th is the 100th anniversary of the birth of Gene Roddenberry. Star TrekIn trying to build a fictional universe to tell some interesting stories and make a little money, he not only succeeded in spawning an enduring science fiction franchise, but also inspired generations of future scientists and engineers.Number of things Star Trek It is surprising that the writers invented to advance their stories and later appeared as actual products. It is as strange as the strange coincidence that the fictional planet Vulcan is placed in orbit around the star 40 Eridani, only to find that there is actually a potential suitable Exoplanets surround the star. Tribute to Roddenberry, Send a message to 40 Eridani using the Deep Space Network last weekA big dish at the Goldstone DSN site in California launched a 20-kilowatt signal on Thursday, starting its 16.5-year stellar journey. We looked up the details of what was sent, but the only description is that it contains a 1976 recording of the Milky Way Bird himself. Whatever it is, it will take at least 33 years to see if we get a response. Mark your calendar.
I have been doing a lot of work on cars lately, and since the newest vehicle in the family fleet is from 2004, this task has become more approachable. I find it very satisfying to work in a car, and I am afraid that one day we will be forced to replace one of our predecessors with something more modern and less suitable for lane maintenance. In other words, there are many things to like about new cars, especially electric cars. There is a way to keep you away from the ICE vehicle while still being able to work on your ride.but if Ford’s tease on EV crate motors this week Happened, it may be the best of both worlds. The motor, with the unfortunate nickname “Eluminator”-just can’t resist putting the “E” there, right? -Should be a direct substitute for internal combustion engines, suitable for “restomod” projects. These car manufactures were designed to make the car look as retro as possible, but fundamentally changed the guts to add functionality-think of the Raspberry Pi running the Spotify client, which is stuffed into the old Atwater Kent cathedral radio. We like the idea of powering old cars, but in our opinion, the crate motor is only part of the answer. Are there such things as crate batteries?
Finally, there is an interesting article detailing a new method Use 3D printing to repair a cracked eardrumThe tympanic membrane is a thin and delicate tissue that can be easily punctured, whether it is blunt trauma, infection, or even loud sounds such as gunshots or explosions. When the tympanic membrane is damaged, hearing will be affected. This hole can be used as a pathway for pathogenic microorganisms to enter the inner ear. Repairing the hole usually requires a graft from the patient’s own tissue, usually from a small dongle covering the ear canal. But this tissue is not as thin as a natural eardrum. Although it can restore hearing, it is usually muddy and deep. The new technology is to use special polymers and printers to 3D print customized implants for patients. The artificial membrane mimics the structure of the natural tympanic membrane and immediately restores more natural hearing. It can also be used as a scaffold for the body to fill natural cells, hoping to restore natural functions after the 3D printed parts are absorbed. This is an interesting job, and the video in the linked article is also very attractive.
