Unless you’ve been living under a rock for the past few years, you’ve likely seen at least one video of the Boston Dynamics Robo-Dog Spot now owned by Hyundai Corporation. If you are also a devoted geek reader You saw one of these in action right here in Israel, with Israeli technology.. Now Facebook robotics and artificial intelligence researchers are taking and updating the concept with their very own robotic dog that knows how to deal with real-world conditions and is armed with some particularly advanced models.

The AI ​​that will improve robots?

A team of researchers from Facebook’s AI division and the American universities of Berkeley and Carnegie Mellon have introduced a new artificial intelligence model called Rapid Motor Adaption (or RMA for short) designed to improve the mobility of robots. The model allows robots to make corrections to their movement in real time, under different conditions and under different circumstances.

The model created by the research teams for the robots is based on the use of two very familiar techniques from the world of AI and machine learning: the first is reinforcement learning (or RL) and the second is supervised learning. Using these techniques, the researchers created a situation in which the robot becomes accustomed to changes in real time, such as the surfaces on which it walks or carries weight without warning, without the help of visual feedback. In other words, while Spot the Dog scans its surroundings with computer vision, Facebook’s bot is ready for failure and quickly adapts to the UAV.

The researchers behind the new model point out that today robots are either manually programmed according to the environment in which they are designed to operate, or they are partially programmed manually, using learning techniques to learn to navigate the environment. On the contrary, RMA, according to the researchers, is the first model based solely on learning techniques that allows robots to adapt to different environments from scratch by moving in space and interacting with the environment.

According to the researchers, the robots they ran the RMA on were able to achieve more successful results than competing systems when it comes to walking on different surfaces, including different gradients and obstacles, and carrying different weights on them as they walk. “It is even more difficult than sophisticated manual programming, because it is difficult or impossible to pre-program a robot to get used to the full range of environments in the world,” the researchers wrote.

Prepare the robot for real life

Investigators who signed Article On the subject of the model developed together with Facebook, they state that no matter how good the teams that develop robots are, their full or partial programming will always be successful under laboratory conditions, but will not hold up in real life testing. According to them, only the use of a model like RMA could give robots the ability to move in space while loading different weights, without the need to repair their software each time; Or the ability to keep walking properly even if they have suffered some damage to one of their “feet” and the ability to adapt to countless changes that can occur in real time.

To address the various challenges of space movement and real-time repairs, RMA relies on two subsystems. The first is a basic policy created by RL-based learning simulations: the researchers stored a lot of information about the different environments (such as the amount of friction in each environment or the different weights thrown at the robot) and from this information they learned to anticipate which settings must do.

However, in real time it is impossible to know exactly which surfaces the robot will encounter, and this is where the second subsystem comes into play: the adaptation module. The basic policy is the one that drives the robot in real time and is designed to operate quickly, otherwise it will freeze in place or crash. Next to it, the adaptation module runs in the background, which takes the information collected from the robot’s sensors and makes the necessary corrections according to this information. The two subsystems operate asynchronously, which also allows for a smaller computational module needed to run RMA, so that in practice there is less weight on the robot.

Using all of these abilities, crews were able to march their RMA-based robot into environments such as sand, mud, walking paths, high meadows, and even a pile of dirt when only one of the experiments failed the mission. Among other things, the robot managed 70% of attempts to go down high stairs, which were found to walk where it walked, and 80% of attempts to walk on piles of gravel and concrete. The robot was also able to walk at 12 kilograms, the same weight as its entire body weight. Additionally, the Robo-Dog was able to steadily walk on an oiled surface which caused the dog without the model to instantly slip.

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

 on

 

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.

This report by The Canadian Press was first published Sept. 9, 2024.
