SEATTLE (Diya TV) — A team of computer scientists from the University of Washington have built a robot hand that can not only perform dexterous manipulation, but also has the ability to learn from its experiences without the assistance of human direction.

The latest results from the trials have been detailed in a paper, which will be presented during this month’s International Conference on Robotics and Automation.

“Hand manipulation is one of the hardest problems that roboticists have to solve,” said Vikash Kumar, a UW doctoral student in computer science and engineering and lead author of the paper. “A lot of robots today have pretty capable arms but the hand is as simple as a suction cup or maybe a claw or a gripper.”

The research team spent years custom-building what has become one of the world’s most highly capable five-fingered robot hands, which possesses a model that enables a computer to analyze movements in real time. In the latest demonstration, the group of researchers applied the model to real-world tasks like rotating an elongated object.

With each attempt, the robot hand becomes more and more adept at spinning the tube, thanks to algorithms that help it model basic physics involved in the action, and the plan required to achieve desired results. See the robot hand in action in the below video.

The movement was developed at the university’s Movement Control Laboratory, and completely contrasts with robotics demonstrations that require people to program a robot’s individual movements in order to complete a task.

“Usually people look at a motion and try to determine what exactly needs to happen — the pinky needs to move that way, so we’ll put some rules in and try it and if something doesn’t work, oh the middle finger moved too much and the pen tilted, so we’ll try another rule,” said senior author and lab director Emo Todorov.

“It’s almost like making an animated film — it looks real but there was an army of animators tweaking it,” Todorov said. “What we are using is a universal approach that enables the robot to learn from its own movements and requires no tweaking from us.”

This research, development and production of the robot hand of course came at a price — $300,000 is what the university has spent thus far on the dexterous robot hand. It uses a shadow hand skeleton actuated with a custom pneumatic system and can move faster than a human hand. The overall result is far too expensive for commercial or industrial use, but has allowed researchers to push core technologies and test innovative strategies.

“There are a lot of chaotic things going on and collisions happening when you touch an object with different fingers, which is difficult for control algorithms to deal with,” said co-author Sergey Levine, who worked on the project as a postdoctoral fellow at University of California, Berkeley.  “The approach we took was quite different from a traditional controls approach.”

Biden & Trump hold separate town halls on debate night | Diya TV News

WASHINGTON (Diya TV)  — It was supposed to be debate night, a second battle between former Vice President Biden and President Trump. But after the President’s COViD-19 diagnosis, an in person battle wasn’t in the cards. The President did not want to do a virtual debate, so both men held separate town halls at the exact same time to try and win over voters with less than three weeks before the election and millions of people already casting their ballots early.

Many of the biggest Desi names in entertainment got together for a virtual ‘South Asian Block Party’ to support the Biden-Harris campaign. In just a couple hours, $250,000 was raised, with a number of the prominent figures sharing their personal stories on why they are supporting the Biden ticket.

Pakistan’s government has banned TikTok, citing complaints alleging the popular video app carried immoral and indecent content.

Simran Sethi, ABC TV’s Executive Vice President of Development and Content Strategy, is putting in place a new set of inclusion standards to ensure the television network accurately reflects society.

Members of the Senate Judiciary Committee began a week of confirmation hearings for US Supreme Court nominee Amy Coney Barrett. Judge Barrett praised the legacies of Justices Ruth Bader Ginsburg and Antonin Scalia. Judiciary Chair Lindsey Graham set the agenda and defended his decision to move Barrett’s nomination forward. Barrett could become the first justice placed on the court right before a Presidential election.

Actress Mindy Kaling took the occasion of being on the “Late Show with Stephen Colbert” to announce she just gave birth to a baby boy named Spencer in September. It’s the second child for Kaling, who told Colbert her daughter Katherine reconnected her to Hinduism after her birth.

President Trump & First Lady contract COVID-19 | Diya TV News

WASHINGTON (Diya TV)  — The world’s attention is focused on the health of President Trump and the first lady after they disclosed they both have the coronavirus. The President is 74 years old and is considered in a high risk category. White House spokespeople say the President was flown to Walter Reed Medical Center for observation and will be there for a few days out of “an abundance of caution.” Sources close to the situation say the President is experiencing a low-grade fever and that he took an experimental drug cocktail to boost his immune system. The First Lady, Melania Trump, remains at the White House. Trump confidants Hope Hicks, Kellyanne Conway and Bill Stepien also contracted the virus.

Well wishes for the President are coming in from around the globe, with one of the first messages of support coming from Indian Prime Minister Modi.

There are tributes around the U.S. to mark Mahatma Gandhi’s 151st birth anniversary. Political leaders sent their well wishes and there was a ceremony at the Indian Embassy in Washington to commemorate the occasion.
