The King Abdullah University of Science and Technology (KAUST) has been developing a new robotic system designed to automate date palm harvesting, SPA reported.
According to a KAUST press release, the system aims to revolutionize the agriculture industry and establish Saudi Arabia as a leader in agriculture innovation. The research, led by KAUST Assistant Professor Shinkyu Park, focuses on automating key processes in date farming, such as harvesting, pollination, and tree maintenance through AI-powered robotics, and promises to yield larger quantities of more nutritious dates.
Park's "robotic farmers" solution combines robotics for reliable farming and AI for greater efficiency. The robotic arms of the system will be able to move as quickly as a human farmer while precisely picking each date without damage to itself or the fruit. Equipped with high-precision visual sensors, the robotic farmers can identify individual dates, flowers, and tree structures to perform tasks such as harvesting, spraying, and pruning, ensuring tree health, productivity, and longevity while reducing the risk of pest infestations and diseases.
Field trials are scheduled to begin during the 2025 harvest season, with full operational capability expected within three years. Park suggested that a Robots-as-a-Service (RaaS) model could allow smaller farmers to access the technology without the burden of purchasing the robots outright.
The project is one of many at KAUST that will benefit date farming and food security. Such projects provide Saudi Arabia an advantage not only in agricultural technology but also in agricultural expertise, as leaders in farming and robotics are drawn to the region, while laborers will be the first to engage with the new technologies developed by Park and his team, according to the release.
"I am excited that this initiative extends beyond engineering solutions and cultivates research and development opportunities for local talent, contributing to the long-term sustainable educational and economic growth of the Kingdom," he said.

President Donald Trump wants to turn Alcatraz, a popular US tourist destination, into a federal prison again, more than 60 years after the California island fortress was shut down as too costly.

Trump says Alcatraz, now part of the National Park Service, suddenly is needed to house America’s “most ruthless and violent” criminals. It's where the government sent notorious gangsters Al Capone and George “Machine Gun” Kelly as well as lesser-known men who were considered too dangerous to lock up elsewhere.

“When we were a more serious Nation, in times past, we did not hesitate to lock up the most dangerous criminals, and keep them far away from anyone they could harm. That’s the way it’s supposed to be,” Trump said Sunday on his Truth Social site.

What is Alcatraz? Alcatraz is in San Francisco Bay off the coast of San Francisco and visible from the Golden Gate Bridge. It is best known for its years as a federal prison, from 1934-63, but its history is much longer.

President Millard Fillmore in 1850 declared the island for public purposes, according to the park service, and it soon became a military site. Confederates were housed there during the Civil War.

By the 1930s, the government decided that it needed a place to hold the worst criminals, and Alcatraz became the choice for a prison.

“A remote site was sought, one that would prohibit constant communication with the outside world by those confined within its walls,” the park service said. “Although land in Alaska was being considered, the availability of Alcatraz Island conveniently coincided with the government’s perceived need for a high security prison.”

Why did it close? The remoteness eventually made it impractical. Everything from food to fuel had to arrive by boat.

“The island had no source of fresh water,” according to the US Bureau of Prisons, “so nearly one million gallons of water had to be barged to the island each week.”

The cost to house someone there in 1959 was $10.10 a day compared with $3 at a federal prison in Atlanta, the government said. It was cheaper to build a new prison from scratch.

Why is Alcatraz notorious? Despite the location, many prisoners tried to get out: 36 men attempted 14 separate escapes into the bay, according to the FBI. Nearly all were caught or didn’t survive the cold water and swift current.

“Escape from Alcatraz,” a 1979 movie starring Clint Eastwood, told the story of John Anglin, his brother Clarence and Frank Morris, who all escaped in 1962, leaving behind handmade plaster heads with real hair in their beds to fool guards.

“For the 17 years we worked on the case, no credible evidence emerged to suggest the men were still alive, either in the US or overseas,” the FBI said.

A national park Alcatraz became part of the Golden Gate National Recreation Area and was opened to the public in 1973, a decade after it was closed as a prison.

The park service says the island gets more than 1 million visitors a year who arrive by ferry. A ticket for an adult costs $47.95. Visitors can see the cells where prisoners were held.
