In 2012, Saudi Aramco hired seven KAUST master's degree graduates holding passports from nine different countries to form the company's Intelligent Systems team. The team's mission: to rapidly prototype intelligent systems—like robots—to solve Aramco's different oil and gas operations challenges.
Originally based at the company's headquarters in Dhahran, the new hires—who were all under the age of 25—began working on their first project, a magnetic robotic inspection crawler.
With their wide-ranging backgrounds in mechanical engineering, electronics engineering and computer science, the team members developed their first robot SAIR, or Saudi Aramco Inspection Robot, taking it from pencil drawings to a fully functional prototype in just 18 months.

SAIR is unique because it can conduct both visual and ultrasonic inspection of Aramco's steel operational assets—like tanks, vessels and pipes—and sense flammable and hazardous gases. It is operated wirelessly; is compact and self-contained; can move on curved surfaces; and detects steel thinning caused by corrosion in difficult-to-access locations. But the project came with a huge number of challenges for the young team.

"Our robots are of an industrial grade, and they have to go through field testing and deployment, which is far from what we were used to in developing academic project robots," explained Hassane Trigui (M.S. '11, electrical engineering), a founding member of the team. "Creating a proof of concept for SAIR at the beginning was very similar to our academic experience, but we found a challenging transition when going into field testing and fulfilling the requirements of our proponents and end users."

"Because we focus on rapid technology development, our design was iterated quickly and all our team members were involved—we went through a learning curve together to adapt," he continued. "No one person can build a robot alone—it's an interdisciplinary field, and teamwork was very important."
"All of our original team members were recruited from KAUST because they were top in their academic fields," noted founding team member Brian Parrott (M.S. '11, chemical and biological engineering). "We formed a 'dream team' to get this done. Even though we were fresh out of school and working in the relatively new field of mobile robotics, we said, 'We can do this,' and we pushed ourselves to make sure we delivered what we promised."

"We were very proud of our accomplishments," said Fadl Abdellatif (M.S. '11, mechanical engineering), another founding member of the team. "This was the first robotics project Aramco came out with, and it was conceived in-house. Few people believed something like this could be done in Saudi Arabia, but we proved we could build an internationally recognized robot here."
The team received a total of 10 patents for SAIR's technology.

"With SAIR, none of this has to be done—inspections and measurements of the pipe wall thickness to prevent potential leaks can all be completed by the robot."

Another important aspect of SAIR's success was the team's partnership with KAUST on campus.

As the team wound up work on SAIR, they began concentrating on their next project—a robot called SWIM-R, or Shallow Water Inspection and Monitoring Robot, which inspects underwater pipelines. This project was even more challenging than the last.

"The objective with SWIM-R was to reduce the use of divers for inspecting underwater pipelines. As with pipes above ground, we have to inspect underwater pipelines periodically to make sure they are in good condition, but diving is dangerous, expensive—especially when sending out a large diving support ship with a diving crew—and not something to be taken lightly. Moreover, large ships cannot access shallow water regions," Abdellatif explained.

The team spent many "long hours under the sun testing prototypes and fixing issues," as Trigui noted. "We had assistance at KAUST from the marine facilities in the Core Labs, where we tested our robot's prototypes in their tanks, and they trained us in designing water-proof enclosures."

The team so far tackled two other key projects: constructing a robotic dust mitigation system for solar panels and producing a technology for measuring Aramco's storage tank volumes.
"We looked around the Kingdom and we saw that even though we have some of the best solar resources in the world, dust is a huge problem for solar power here—it makes it much more expensive to capture solar power," explained Parrott.
The team went through three product iterations to produce a simple, cheap system reducing the impact of dust on solar panels. Unlike with SWIM-R, their first versions had more features than the last.
The Intelligent Systems team’s work on robotic dust mitigation produced a prototype that resulted in three patents and two published journal papers. Image courtesy of Saudi Aramco.
Their final product resulted in three patents and two journal paper publications "because we found really clever ways of solving problems," he continued. "It was fun for us to look at a problem, find a solution that's totally different from what is out there on the market and make it simpler."
The team's technology has now been licensed to on campus-based startup NOMADD, with tests ongoing at the campus's New Energy Oasis.
In the space of one year, the team produced its technology—called Custody Tank Transfer Calibration, or CTTC—to better and more frequently measure the volume of Aramco's custody and royalty tanks. These function as transfer tanks for crude oil and other refined products being transported to customers.

To keep an accurate estimation of volume, a manual process involving multiple workers measuring the tanks by hand must be done, which is costly and slow.
"We set out to keep our technology as simple as possible: there is a robot that travels along the tank and a station that shoots a laser beam which is stuck in the bottom of the tank. The robot crawls up the tank and—through the use of the laser beam—can detect if the tank is bulging outward or inward, building a complete profile of the tank's volume," Abdellatif explained. "Our automated process is much faster and more attractive for the end users."

"There are few teams working in robotics in Saudi Arabia," noted team member Mohammad Ababtain, who joined Intelligent Systems in late 2015. "We're one of the 'beginners' in that area, but we're working hard to make sure the Kingdom will lead in robotics in the future."
"We feel our work gives Saudi Arabia more of a 'technology-creator' status than just a 'technology-user' status," Patel said. "We also want to contribute to Saudi Arabia's focus on future smart cities—these cannot be created without robots and intelligent systems."

"We're proud of saying our technologies are 'made in Saudi Arabia,'" said Abdellatif. "We want to continue improving the Kingdom's knowledge-based economy by gathering knowledge and building skills—through addressing the challenges Aramco faces every day."
