UAV / UCAV / LAR (robotit) Uutiset ja jutut


Ships at sea are literally islands unto themselves. If what you need isn’t on board, good luck getting it in the middle of the Pacific. As such, most ships are really well equipped with spare parts and even with raw materials and the tools needed to fabricate most of what they can’t store, and mariners are famed for their ability to make do with what they’ve got.

But as self-sufficient as a ship at sea might be, the unexpected can always happen. A vital system could fail for lack of a simple spare part, at best resulting in a delay for the shipping company and at worst putting the crew in mortal danger. Another vessel can be dispatched to assist, or if the ship is close enough ashore a helicopter rendezvous might be arranged. Expensive options both, which is why some shipping companies are experimenting with drone deliveries to and from ships at sea.

Jos droneilla riittäisi potkua kuljettaa a-tarvikkeita niin tämä voisi olla hyvä lisä laivan pitämiseksi vesillä sataman sijasta.
 
Google parent firm Alphabet has trimmed down a bit, and offloaded two robotics companies to the Japanese money machine called Softbank.

Boston Dynamics is going for an undisclosed sum, and Google will no longer be associated with robots that terrify people when they are not being shoved around by technicians. Softbank, which must have more money than sense, is also taking Schaft with it, but again we do not know how much money is changing hands.

Boston Dynamics is probably a good buy for it. It gets decent press, at least according to the News section of its website, and certainly grabs all the attention whenever one of its robots gets wheeled out or unleashed into the wilderness.

It is unclear if the company will pack up its bi-pedal frightbots and move to Japan, but in the meantime, everyone seems happy enough.

"We at Boston Dynamics are excited to be part of SoftBank's bold vision and its position creating the next technology revolution, and we share SoftBank's belief that advances in technology should be for the benefit of humanity," said Marc Raibert, CEO and founder of Boston Dynamics.

"We look forward to working with SoftBank in our mission to push the boundaries of what advanced robots can do and to create useful applications in a smarter and more connected world."

Over at Softbank and people are equally effusive. "Today, there are many issues we still cannot solve by ourselves with human capabilities. Smart robotics are going to be a key driver of the next stage of the Information Revolution, and the team at Boston Dynamics are the clear technology leaders in advanced dynamic robots," said Masayoshi Son, chairman & CEO of SoftBank Group.

"I am thrilled to welcome them to the SoftBank family and look forward to supporting them as they continue to advance the field of robotics and explore applications that can help make life easier, safer and more fulfilling."

According to the Softbank statement, Schaft is going along as part of the transaction, no such glorious statements are laid out for it. We might say that it has been Schafted.

A traditional quadcopter is designed to achieve 6 degrees of freedom — three translational and three rotational — and piloting these manually can prove to be a challenge for beginners. Hexacopters offer better stability and flight speed at a higher price but the flight controller gets a bit more complex.

Taking this to a whole new level, the teams at the Swiss Federal Institute of Technology (ETH Zürich) and Zurich University of the Arts (ZHDK) have come together to present a hexacopter with 6 individually tiltable axes. The 360-degree tilt in rotors allows for a whopping 12-degrees of freedom in flight and allows the UAV to fly in essentially any direction including parallel to walls.

In addition to the acrobatic capabilities of the design, the team has done some testing with autonomous control using external cameras. Their blog contains videos of their testing at various stages and it interesting to see the project evolve over a short span of nine months. Check out the video below of the prototype in action.

Video Drones can perform three-dimensional imaging of objects through walls using Wi-Fi, a team of researchers demonstrated for the first time.

Chitra Karanam, a PhD student, and Yasamin Mostofi, a professor at the department of electrical and computer engineering at the University of California, Santa Barbara, presented their results [PDF] at the Association for Computing Machinery/Institute of Electrical and Electronics Engineers International Conference on Information Processing in Sensor Networks.

“Our proposed approach has enabled unmanned aerial vehicles to image details through walls in 3D with only Wi-Fi signals. This approach utilizes only Wi-Fi RSSI measurements, does not require any prior measurements in the area of interest and does not need objects to move to be imaged,” Mostofi said on Monday.

RSSI stands for received signal strength indicator. A drone beams radio waves at 2.4GHz, and another drone on the other side of the wall measures the power of the signals.

The researchers used two 3D Robotics RTF X8+ drones, measuring 40 x 40cm (15.7 x 15.7in) and weighing 3.5kg (7.7lb) each.

The strength of the received signal drops by a certain level depending on the presence of objects through the wall, Mostofi explained to The Register.

Linkin alla autonomista navigointia.

Rats are nimble navigators, able to find their way around, under, and over obstacles, and through the tightest spaces. Roboticists have long dreamed of giving their creations similar navigation skills. To be useful in the real world, robots must be able to find their way around on their own. Some are already learning to do that in homes, offices, warehouses, hospitals, and hotels—and in the case of self-driving cars, entire cities. Despite that progress, robots still struggle to perform the tasks for which they’re designed even under mildly challenging conditions.

At the Queensland University of Technology, in Brisbane, Australia, Michael Milford and his collaborators have spent the past 14 years honing a robot navigation system modeled on the brains of rats. This biologically-inspired approach, they hope, could help robots navigate dynamic environments without requiring advanced, costly sensors and computationally-intensive algorithms.

Mielestäni jääkärikomppanioihin olisi syytä saada lennokkipartio. Joku yksinkertainen semikaupallinen lennokki ja tusinan verran vieläpä olisi nannaa.

Kyllä ja pienemmät jopa joukkueille asti haipeissa.

Olisi mielenkiontoista kehitellä lennokkien avulla aktivoitavia ottawa-henkisiä miinoitteita.

Myös lennokkien torjunta kaipaa jotain. Elsohommiahan nämä ovat.

Joukkuetasosta en ole ihan niinkään innoissani, en sinne lisäisi lennokkeja.

Arvaan, että haluaisit pitää päätöksen noiden käytöstä komppanian päälliköllä? Siis että JJ ei päätä laittaa lennokkia ilmaan ja paljasta sillä olemassaoloaan?

1. Turhia päällekkäisiä toimintoja. Komppania toimii sen verran pienellä alueella, että yksi lennokkipartio kykenee tuottamaan tarvittavan tilannetiedon sekä maalinosoituksen koko komppanian tarpeisiin. Toki pataljoonan tiedustelujoukkue kykenee kattamaan suurimman osan vastuualueesta, mutta tiedustelutiedoissa ei kyetä kertomaan kuitenkaan ihan ajantasaisinta tilannekuvaa. Esim komentajan hyökkäyskäsky saattaa käyttää kolme tuntia vanhaa lennokin tilannetietoa. Tällöin komppanialla on mahdollisuus ulottaa nopeasti raakatiedustelu tavoitteeseen saakka lennokilla sekä sen perusteella tarkentaa tilannekuvaa tossutiedustelulla.
2. Komppanian "ilmatilan" hallinta, lennokeja voi olla mahdoton tunnistaa omaksi tai vihollisen
3. Tilannetiedon jakaminen ja ylläpito tapahtuu komppanian komentopaikalle. Sen yhteydessä toimiva lennokkipartio kykenee nopeiten toimittamaan tiedon tarvitsijoille sekä mahdollistaa TJPÄÄL:lle nopean tulenkäytön, koska yhdessä päällikön kanssa voivat muokata vastuualueita ja käskeä joukkoja tarvittaessa väistämään epiksen tieltä.

Nämä nyt tulee ekana mieleen.
 
Minusta joukkuetason pienlennokit/kopterit voisivat olla perusteltuja haippien kohdalla. Joukkue tai joukkueparin iskuosastot ovat niissä tyypillistä toimintaa. Niille reaaliaikainen lähialueen tieto olisi omiaan irtautumisen varmistamisessa ym.

Komppania/pataljoonatasolla olisi sitten ne kyvykkäämmät lennokit, joiden tuottamalla tiedolla voidaan laatia suunnitelmia ym.
