Robotics breakthrough: Scientists make artificial skin

by Richard Ingham Richard Ingham 2 hrs 36 mins ago

PARIS (AFP) Biotech wizards have engineered electronic skin that can sense touch, in a major step towards next-generation robotics and prosthetic limbs.

The lab-tested material responds to almost the same pressures as human skin and with the same speed, they reported in the British journal Nature Materials.

Important hurdles remain but the exploit is an advance towards replacing today's clumsy robots and artificial arms with smarter, touch-sensitive upgrades, they believe.

"Humans generally know how to hold a fragile egg without breaking it," said Ali Javey, an associate professor of computer sciences at the University of California at Berkeley, who led one of the research teams.

"If we ever wanted a robot that could unload the dishes, for instance, we'd want to make sure it doesn't break the wine glasses in the process. But we'd also want the robot to grip the stock pot without dropping it."

The "e-skin" made by Javey's team comprises a matrix of nanowires made of germanium and silicon rolled onto a sticky polyimide film.

The team then laid nano-scale transistors on top, followed by a flexible, pressure-sensitive rubber. The prototype, measuring 49 square centimetres (7.6 square inches), can detect pressure ranging from 0 to 15 kilopascals, comparable to the force used for such daily activities as typing on a keyboard or holding an object.

A different approach was taken by a team led by Zhenan Bao, a Chinese-born associate professor at Stanford University in California who has gained a reputation as one of the top women chemists in the United States.

Their approach was to use a rubber film that changes thickness due to pressure, and employs capacitors, integrated into the material, to measure the difference. It cannot be stretched, though.

"Our response time is comparable with human skin, it's very, very fast, within milliseconds, or thousandths of a second," Bao told AFP. "That means in real terms that we can feel the pressure instantaneously."

The achievements are "important milestones" in artificial intelligence, commented John Boland, a nanoscientist at Trinity College Dublin, Ireland, who hailed in particular the use of low-cost processing components.

At First Denied Visas, Afghan Girls' Robotics Team Arrives in US
Sunday 16th July, 2017 - Afghanistan's all-girl robotics team has arrived in the U.S. for a competition after President Donald Trump personally intervened to allow them into the country.
The U.S. embassy in Kabul had denied visas for the girls earlier this month for unknown reasons. However, VOA's White House bureau chief, Steve Herman, reported Wednesday that Trump granted the girls what is known as a parole - reversing the earlier decision to bar them from the U.S. - that will allow them to come to Washington for 20 days. A student team from Gambia also was granted visas last week after initially being rejected.

The president of FIRST Global, which organized the robotics competition, is former Democratic congressman and retired U.S. Navy Admiral Joe Sestak. He thanked the White House and the State Department for clearing obstacles to the Afghan and Gambian students' travel to the United States. Teams from all 157 countries that have entered the competition now will be taking part, he added.

The three-day robotics competition begins Sunday in Washington. FIRST Global Challenge holds the yearly contest to build up interest in science, technology, engineering and math across the world. The group says the focus of the competition is finding solutions to problems in such fields as water, energy, medicine and food production.

Afghan girls will be allowed into US for robotics contest
July 12, 2017 | WASHINGTON (AP) — U.S. officials will allow a group of Afghan girls into the country to participate in an international robotics competition after President Donald Trump intervened, White House spokeswoman Sarah Huckabee Sanders confirmed Wednesday, ending a saga that had sparked international backlash.
Homeland Security Department spokesman David Lapan said the U.S. Citizenship and Immigration Services approved a State Department request for six girls from the war-torn country to be allowed in, along with their chaperone, so they can participate in the competition. The girls' applications for U.S. visas had been denied twice. The non-profit organizing the competition celebrated the reversal in a jubilant statement Wednesday. "I truly believe our greatest power is the power to convene nations, to bring people together in the pursuit of a common goal and prove that our similarities greatly outweigh our differences," said Joe Sestak, the president of First Global. He credited "the professional leadership of the U.S. State Department" for ensuring that all 163 teams from 157 countries, including a team of Syrian refugees, would be able to participate.

The U.S. State Department had declined to comment on why the Afghan team's visa applications were denied, saying that "all visa applications are adjudicated on a case-by-case basis in accordance with U.S. law." A senior administration official said that Trump raised the issue with his national security adviser, H.R. General McMaster, during his trip to Germany last week for the Group of 20 summit, and had asked for additional options. The State Department and Department of Homeland Security came up with several — with the idea of "paroling" the girls through the Department of Homeland Security ultimately chosen by the National Security Council. The person spoke on condition of anonymity to discuss the private deliberations.

Teenagers from the Afghanistan Robotic House, a private training institute, practice at the Better Idea Organization center, in Herat, Afghanistan. U.S. President Donald Trump intervened to allow the group of Afghan girls into the country to participate in a robotics competition. White House spokeswoman Sarah Huckabee Sanders confirmed the president’s intervention Wednesday, July 12, 2017. The six female students from Afghanistan had hoped to participate in an international robotics competition this month, but their visa applications to enter the U.S. were denied twice.

Parole is a temporary status in which a person who is otherwise ineligible to enter the country is allowed in temporarily because of an emergency or humanitarian purpose, or because it's deemed to be in the public good. Without the reversal, which was first reported by Politico, the girls would have had to watch via video link from their hometown in western Afghanistan. The girls wanted to show the world that Afghans could also construct a hand-made robot and they had been deeply disappointed by the initial rejections. "When we heard that we were rejected we lost hope," said 14-year-old Sumaya Farooqi. "We applied again for the U.S. visa and we were rejected again."

Farooqi and her teammates faced seemingly insurmountable obstacles to even get to a point where they could seek permission to attend. It took them six months to prepare, often working seven days a week, as they constructed a robot that sorts balls, has the ability to recognize orange and blue colors, and can move objects to put them in their correct places. The girls traveled from their homes in Herat after convincing family members to let them go — no small feat in a country where young girls are often discouraged from pursuing academic study, especially in hard sciences such as math.


U.S. To Allow Entry For Afghanistan’s All-Girl Robotics Team After First Denying Request
7/12/2017 - “We could not be prouder of this delegation of young women who are also scientists,” a U.S. official said.
After a group of six teenage girls in Afghanistan were denied entry into the U.S. for a robotics competition, Department of Homeland Security officials have changed course and are allowing them to compete. The girls will not be granted visas, but instead “parole,” allowing them to stay in the U.S. for 10 days ― a reversal that occurred after President Donald Trump intervened in the matter, Politico reported. The teens will be able to take their robot to the FIRST Global Challenge, an international robotics competition in Washington this month.

I look forward to welcoming this brilliant team of Afghan girls, and their competitors, to Washington DC next week! #WomenInSTEM https://t.co/01qDduyglS

The Citizenship and Immigration Services office, which is part of DHS, approved the request from the Department of State to authorize the girls’ team and their chaperon, department spokeswoman Joanne Talbot confirmed to HuffPost. After creating their robot and entering it in the competition, the girls made a . 500-mile trip ― twice ― from their home in Herat to the U.S. embassy in Kabul hoping to obtain the temporary visas needed to compete. When they got news their visas would be denied, the girls were “crying all the day,” Roya Mahboob, the first female CEO of a tech company in Afghanistan and the organizer of the girls’ project, told Forbes at the time.

Now they’ll have their chance. “The State Department worked incredibly well with the Department of Homeland Security to ensure that this case was reviewed and handled appropriately,” Dina Powell, White House deputy national security adviser for strategy, told Politico in a statement. “We could not be prouder of this delegation of young women who are also scientists ― they represent the best of the Afghan people and embody the promise that their aspirations can be fulfilled. They are future leaders of Afghanistan and strong ambassadors for their country.” The competition will take place this coming Sunday through Tuesday.
