It flies like Superman, crawls through small spaces like a cockroach, delivers packages like your favorite pizza-shop messenger and drives like a Formula One World Champion. The world’s first experimental robot drone that soars into the sky like a typical quadcopter, drives on tough terrain and squeezes into tight niches using the same motors, has been developed by imaginative and skilled researchers at Ben-Gurion University of the Negev (BGU) in Beersheba.

The hybrid FSTAR (flying sprawl-tuned autonomous robot) is due to be introduced at the International Conference on Robotics and Automation 2019 in Montreal, Canada on May 20. It was developed in BGU’s Bio-Inspired and Medical Robotics Lab by Prof. David Zarrouk, a senior lecturer in BGU’s department of mechanical engineering and head of the Bio-Inspired and Medical Robotics Lab, together with his graduate student, Nir Meiri.
The department was among the first established in the nearly 50-year-old university. The first class graduated in 1970, and many of them remained in the Negev to work.
Its research focuses on modeling, designing and manufacturing of unique robots, including miniature crawling robots and serial crawling robots for search & rescue applications, space, maintenance, agricultural and medical purposes. They specialize in designing minimally actuated robots that are easy to control and operate, as well as on modeling the interaction between robots and slippery and compliant environments. Our manufacturing techniques include machining, laser cutting, and 3D printing.
FSTAR can fly over obstacles or run underneath them. The sprawl, which adjusts from a flat configuration to 55 degrees, makes it possible for the bug-like robot to transform its movement from a flying quadcopter to a car-like robot. It also adjusts its width to crawl or run on flat surfaces, climb over large obstacles and up closely-spaced walls, or squeeze through a tunnel, pipe or narrow gaps.
It can run on the ground at a speed of up to eight feet per second (2.6 meters per second). That – combined with low energy consumption using the same motors – makes FSTAR ideal for a broad range of applications that may need a longer work time.
Possible commercial uses are package deliveries, since it can quickly fly to a target zone and then drive using its wheels safely and quietly to reach the recipient’s doorstep. FSTAR can also be used for search and rescue applications as it can fly over various obstacles and crawl between or underneath cracks where a regular drone cannot fly. The robot can also be used for agriculture, maintenance, cleaning, filming, entertainment, law enforcement and anti-terrorist applications.
“We plan to develop larger and smaller versions to expand this family of sprawling robots for different applications, as well as algorithms that will help exploit speed and cost of transport for these flying/driving robots.”. Zarrouk noted.
Zarouk earned his master’s degree in stochastic mechanics and doctoral degree in medical robotics at the Technion-Israel Institute of Technology in Haifa. Between Aug. 2011 and Oct. 2013, he did a postdoctoral fellowship at the biomimetics and millisystems lab at the University of California at Berkeley, working on miniature crawling robots. He received many prizes for excellence in research and teaching, including a Fulbright fellowship, Fulbright-Ilan Ramon postdoctoral Fellowship, Hershel Rich Innovation award and an Alfred and Yehuda Weisman prize for consistent excellence in teaching.
His research was supported in part by the Helmsley Charitable Trust through the Agricultural, Biological and Cognitive Robotics Initiative (ABC Robotics) and by the BGU Marcus Endowment Fund. The Marcus legacy gift, of over $480 million, was donated in 2016 to American Associates, Ben-Gurion University of the Negev by Dr. Howard and Lottie Marcus. The donation is the largest gift given to any Israeli university and is believed to be the largest gift to any Israeli institution.
The ICRA conference is bringing together the world’s top researchers and most important companies to share ideas and advances in the field. Many of the most important developments in robotics and automation have historically been first exposed at ICRA, and 2019 will take this trend one step further. As the practical and socio-economic impact of our field continues to expand, the role of industry-centered activities has grown and will be a critical aspect of the meeting.

The acting chief of the UN nuclear watchdog policing Iran‘s nuclear deal with major powers, Cornel Feruta, will meet senior Iranian officials in Tehran on Sunday, a spokesman for the International Atomic Energy Agency said on Friday.
“The visit is part of ongoing interactions between the IAEA and Iran,” the spokesman said

The World Zionist Organization (WZO) on Friday opened a three-day conference in Santiago, the capital of Chile, on the topic of confronting antisemitism in Latin America.
Convened by WZO vice-chair Yaakov Hagoel, the conference will involve 150 Jewish professionals from around the region who will receive briefings from “high-level experts in the field to deal with the growing phenomenon,” the Spanish-language Jewish news outlet Diario Judio reported.

JNS.org – For most olim, moving to Israel is the realization of a dream. After years of hoping and planning, making aliyah and taking root in the Jewish state is a joyous and exultant experience. Still, the big move is not without its challenges, and many new immigrants become frustrated while attempting to navigate Israeli bureaucracy, secure a job, and find the right neighborhood to call home.

JNS.org – “It’s so much more.” That’s the mantra of the 54 Jewish young adults from across North America who just wrapped up 10 weeks in Israel.
Sure, they had applied to the Birthright Israel Excel program for a once-in-a-lifetime opportunity to intern at Israeli offices of such top global companies as Facebook, Visa, Microsoft, Ernst & Young (EY), and Barclay’s.
Last week, U.S. Secretary of State Mike Pompeo’s announced that the State Department will consider allowing U.S. citizens born in Jerusalem to list “Jerusalem, Israel” on their U.S. passports.
“We’re constantly evaluating the way we handle what can be listed on passports,” he told JNS in a wide-ranging interview. “It’s something that’s actively being looked at.”
The Palestinian Authority Foreign Ministry responded to this in a statement published in Wafa News saying the move was “an emphasis by the administration of President Donald Trump to antagonize the Palestinian people and undermine any chance for peace on the basis of a two-state solution.”
If you’re Jewish, how afraid should you be of being a victim of a violent anti-Semitic hate crime? In the wake of the Pittsburgh and Poway synagogue shootings in the last year, many American Jews remain afraid. The specter of white-supremacist hate that fueled those and other mass shootings has become the primary focus of those tasked with fighting and monitoring anti-Semitism.
If the use of Nazi symbolism in fashion was manifested in isolated cases, there would be only slight cause for concern. But when this trend is backed or glossed over by giants such as Amazon, the biggest online sales platform in the world, we cannot remain indifferent. From home decor to clothing and accessories, the popular website is infested with products depicting Holocaust victims heading to the gas chambers and images glorifying the Third Reich.
When the Second Intifada broke out in 2000, Hamas founder Sheikh Ahmed Yassin boasted that the desire of his people for death in the service of Hamas was greater than the Israelis’ desire to live. Yassin, of course, was not referring to himself; happy to send his people off to die, he himself clung to life and even believed that his advanced age and status would protect him. But nothing lasts forever, and in March 2004, he was killed in an Israeli airstrike.
Egypt’s leading authorities have reinstated a notoriously “radical” cleric and hate preacher to the pulpit (minbar), despite strong opposition.
According to Arab Weekly, “The Egyptian Ministry of Religious Endowments, which controls the mosques, gave Yasser Burhami, the deputy head of the Salafist Call, the umbrella organisation of Salafi movements, approval to deliver sermons before Friday prayers at the Wise Caliphs Mosque in Alexandria.”
This week’s Torah reading Shoftim, maps out for us, the ideal national structure, of the Jewish people in their homeland, the Land of Israel. It describes the policies that Jews should be striving to implement today: Malchut/Kingdom, Sanhedrin/Torah, Nevuah/Prophecy, and Kehunah/Temple.
