Robot coworkers: How AI impacts the future of work


November 8, 2019

What happens when technology advancements threaten to automate people’s jobs?

That question is on the minds of many as research and development in artificial intelligence and machine learning rapidly advances. man working with a robot in a lab Pulkit Verma, a graduate student member of Siddharth Srivastava’s research team, helps with efforts to reprogram autonomous robots using artificial intelligence.

A new project led by Siddharth Srivastava, an assistant professor in the School of Computing, Informatics, and Decision Systems Engineering at Arizona State University, aims to help alleviate this concern.

Srivastava and his multidisciplinary team are creating autonomous systems that are not only more adaptable and efficient in manufacturing environments, but also have built-in intelligent tutoring systems that will cooperate with factory workers and retrain them to use AI technology so they are not displaced from their jobs.

Funded by a $1 million grant from the National Science Foundation as one of its Convergence Accelerator awards, the project is highly focused on using AI to augment the workplace rather than replace workers.

“Suppose you have this new robot, it’s very efficient, but you need to hire five computer science graduates to operate and maintain it instead of five current factory workers,” Srivastava said. “That’s not feasible, first of all because we don’t have that many computer science graduates in society. Our idea is that instead of getting people to enroll in a new college program again, what we can do instead is design our AI systems, our robots, in a way that will help people to come on board.”

Srivastava is collaborating with ASU faculty members in the Ira A. Fulton Schools of Engineering and the School for the Future of Innovation in Society to bring the project to life.

“We have 10 team members, including experts in robot control, tutoring systems and human systems engineering — a field that involves thinking about how the robot and the human would interact and how you would build a situation where the human trusts the robot,” Srivastava said. “We also have experts in law to help solve the sociotechnical aspects of the problem.”

How artificial intelligence can preserve jobs

Traditionally, AI has mostly been developed with a mind to automate human-performed tasks — that is, to perform tasks in place of a human. For example, machines play chess better than humans do and are also faster at distinguishing patterns and performing calculations. One example of AI working to augment human-performed tasks rather than replace them can be found in intelligent tutoring systems.

The ASU team is focusing on this interaction, particularly in implementing the intelligent training systems for factory workers. This eliminates the concern about driving up the demand for highly educated workers to unsustainable levels and also empowers human workers to incorporate AI into their work.

According to Subbarao Kambhampati, a professor of computer science, this education-based relationship is the key to successful collaboration between AI and humans. In particular, the AI systems need to learn to model the mental states of the humans they collaborate with, and use those models to guide their interactions with the humans.

“We are now considering scenarios in which the AI system teaches humans on the job,” Kambhampati said. “If you are using one machine, and there is a big technological advancement, then the question is what is the best way to get people to come up to speed in using these new machines?”

This retraining process is essential to helping factory workers in the evolving manufacturing industry keep their jobs. It’s a necessary transition into a future when machines can augment human activities without replacing the people who have traditionally performed them.

In that scenario, workers would be able to assign robots a wider variety of tasks while the robots teach workers how to use the robots and why robots are making the decisions they do.

“(Robots) are more adaptable in that their behavior adapts to the changes in their environment, they adapt to the tasks that you give them and at the same time they can answer your questions,” Srivastava said. “A worker who doesn’t know the internals of the robot can ask it, ‘Why did you go along this path when I think you should have just gone straight?’ And the robot can answer, ‘If I go this way then my hand might collide with that table.’ So, in that process, the worker learns about the robot’s constraints and how to operate it.”

Moving toward a more robotic future

Could machines ever replace humans? Is it cheaper to have an all-robotic workforce?

The answer is complicated, said Katina Michael, a professor jointly appointed in the School for the Future of Innovation in Society and the School of Computing, Informatics and Decision Systems Engineering, one of the six Fulton Schools.

“At face value, initially it seems that robots would do better than the operational expenditure of the human labor force,” she said, “but when you look at this quite clinically, you’re almost shifting costs from the human labor force to the robotic labor force. It’s quite debatable as to whether costs will be reduced.”

While robots can operate 24/7, people need breaks, time off, insurance coverage and compensation. However, robots must be updated and maintained, and they also need power to operate — human workers are still extremely necessary in the workplace.

Although the research project is focused on AI development, it is ultimately centered around training human workers and ensuring job security. The team wants to enhance communication between both humans and robots to obtain the best of both worlds in the manufacturing industry.

“Sadly, training diminishes with the increased cost of the capital investment,” Michael said. “Many corporations are trying to save money somewhere, but training is where we need to invest more money in order to have a successful integration of workers and autonomous systems so we can minimize safety risks. If we don’t have adequate training, we don’t have adequate responses to reducing the incidence of on-the-job disasters.”

An interdisciplinary interaction

In highly multidisciplinary projects involving diverse skill sets and expertise in multiple areas, there are many factors to consider when humans team up with robots.

“We’re interested primarily in how humans and robots work together,” Michael said. “With the humans doing their bit and the robots doing their bit, we want to see if there is any incongruousness or congruousness that can be observed. I’m also looking not only at the economic impact but also the societal impact, seeing if the workers who are interacting with these robots are receiving adequate training.”

Erin Chiou, an assistant professor of human systems engineering at The Polytechnic School, one of the six Fulton Schools, is studying the interactions of humans and machines for data to guide the design of systems that prioritize the collaboration of humans and robots.

“Ultimately, it’s getting that multidisciplinary conversation going between people who actually build the machines and people who think very critically about job design and human workers,” Chiou said. “It is relatively easy to optimize technology when you aren't thinking too deeply about how to involve people, because once you involve people, you introduce variation into the system. This makes the problem much more difficult. At the same time, this variation — or the ability for a system to adapt to different situations — is crucial for technology acceptance and for overall system performance.”

The ASU team also has experts looking at the legal, social and economic implications of implementing such technology in the workplace, all of which will be considered when designing the new systems.

“It’s not about changing the hardware, it’s about how to change the software,” Srivastava said. “We’re thinking about how it should act and what it should do. We are rethinking how a robot’s ‘mind’ should work in order to make it more amenable to providing on-the-job training and collaborating with humans.”

Sun Devil Alka Rocketeers to compete in 2019 Bayer Alka-Rocket Challenge


November 8, 2019

Practically everyone knows that Alka Seltzer tablets mixed with water are a go-to effervescent remedy for indigestion.

But did you know that a mixture of Alka Seltzer tablets and water in an enclosed cylinder can produce enough pressure to launch a rocket?

Several Arizona State University students, calling themselves the Sun Devil Alka Rocketeers, know it and are using their skills in engineering and design — and yes, their knowledge of the benefits and power of Alka Seltzer — to compete in the national 2019 Bayer Alka-Rocket Challenge. The competition pits teams from four-year accredited universities throughout the country against each other to see who can design, build and launch a rocket powered by Alka Seltzer tablets and water the highest.

Joshua Pardhe, a Barrett, The Honors College sophomore and president of the Alka Rocketeers, founded the organization last year with three members (all engineering majors) and pushed for official student organization designation and funding through the Ira A. Fulton Schools of Engineering at ASU. The Alka Rocketeers is now an official student organization within the Fulton Schools and has 18 members with a mix of majors, including engineering, business and liberal arts. Most members are Barrett, The Honors College students.

Last year, the Alka Rocketeers was the first-ever team from ASU to compete in the Bayer Alka-Rocket Challenge. Their rocket was made out of PVC piping, a pressure chamber, a removable launch tube and a 3D printed rocket with an altimeter inside.

This year, the group has perfected its design and built a launcher out of pressure-rated PVC piping and brass valves and a rocket that was custom-designed out of ABS plastic and 3D printed at the Fulton Computing, Informatics, and Decision Systems Engineering Print Lab. They hope to launch their rocket at least 200 feet for the Alka-Rocket Challenge. In testing, the rocket reached 154 feet.

Participants in the Alka-Rocket Challenge go through two rounds of competition that run concurrently. One round requires participants to submit a video and a document explaining how they built their Alka-Rocket, any challenges they faced and how they responded, and showing their rocket in action. A professional panel of judges chooses four finalists, each one representing a census region of the United States.

WATCH: View the Sun Devil Alka Rocketeers’ video on YouTube.

The other round of competition involves a public voting period where a photo of each participating team is posted on Facebook and each “like” on the photo counts as a vote for that team. The team with the most “likes” will become the fifth finalist.

VOTE: Vote for the team photo. The public voting period ends Nov. 15.

The five finalist teams, which will be announced Nov. 18, will win a trip for four team members to the Kennedy Space Center in Florida to compete with other teams to see whose rocket can fly highest.

The official competition launch will take place Dec. 12. The team that breaks the existing highest-flying Alka-Rocket record wins a Guinness World Record title and $5,000. The team that launches its rocket the highest and recovers it wins $25,000. The team that achieves both feats wins $30,000.

The Alka Rocketeers are hosting several events to promote their project and ask for votes:

• Rocketpalooza, ASU’s first-ever rocketry expo with music, food, and games, will be held 6 to 8 p.m., Nov. 8, at the Sun Devil Fitness Center on the ASU Tempe campus.

Rocketpalooza will feature volleyball and dodgeball tournaments, with the winning teams entered into a raffle for an Airpod giveaway. Students interested in participating can register at http://bit.ly/Rocketpalooza2019Volleyball or check in at the event and be assigned to a team. The Alka Rocketeers’ rocket will be on display and launched several times throughout the event. Alka Rocketeers will be available to share information about their organization and how others can join the group.

• Puppies and Propulsion, an event where students can pet puppies and learn about the Alka Rocketeers and its rocket, will be held 2 to 4 p.m., Nov. 12 in Palm Court, located at the main entrance of Barrett, The Honors College’s Tempe complex.
