Robots taking over the world? It's a good thing, researchers say

January 26, 2018

Presentations at ASU-hosted Southwest Robotics Symposium explore the ways AI and control systems will make our lives better

Pope Francis, Elon Musk and Hollywood science fiction writers regularly envision smart robots taking over jobs and invading our privacy. Presentations at a symposium at Arizona State University this week, however, established that the next generation of robots will be assisting humanity rather than contributing to its doom.

“We are not all going to die because of robots,” said Aaron D. Ames, from the California Institute of Technology and plenary speaker at the Southwest Robotics Symposium. “Let’s keep these comments in context. They need to learn more about AI and robotics.” 

According to Ames, the humanoid robots we see going viral in social media, like Google-owned Boston Dynamics’ Atlas walking through snow and doing backflips, are all control driven. “There’s zero AI on those robots,” Ames said.

“But, there’s tremendous potential to bring AI and control together on robotic systems in ways that will make our lives better, such as improve mobility for the impaired, aid in disaster response and enable space exploration,” he said.

The symposium, in addition to serving as a platform for researchers to learn about developing technologies and establish collaborative relationships, is also providing a framework to present robotics in terms that aren’t threatening. 

“We are developing ways to talk about our research in the context of helping humans,” said Panagiotis Artemiadis, symposium committee chair and an associate professor in ASU’s Ira A. Fulton Schools of Engineering. “The majority of the work we do is about enriching lives.”

Bio-inspired robotics

Bio-inspired robotics takes concepts in nature and applies them to engineering design. Examples at ASU include studying basilisks and octopuses to develop robots that can work in complex terrains for purposes like search and rescue, execute tasks on asteroids or other planets, and employ suction technologies for gripping and climbing.

“A collaborative team at ASU also is creating bio-inspired systems, using ferrofluids, or magnetic fluids, that can subdivide and regenerate,” said Hamid Marvi, an assistant professor in the ASU’s School for Engineering of Matter, Transport and Energy. “These bio-inspired breakthroughs will be valuable in a wide range of medical applications, such as targeted drug delivery, microsurgery and tissue biopsy.”

Assistive devices

According to Thomas Sugar, an engineering professor at ASU’s Polytechnic School, assistive devices are moving into the mainstream.

“Sitting is the new smoking,” he said. “It increases the chances of heart disease, which is now killing more people than communicable diseases.”

In answer, assistive devices offer a boost to humans: Wearable exoskeletons support hips and knees to enable standing at a workstation, and locomotion systems are designed to assist warehouse workers to travel from one end of the facility to another.

Mechatronic technologies are being combined with soft robotics to create delicate, user-friendly devices for people with muscle-impairment diseases like muscular dystrophy, giving them the ability to grip and move items they otherwise could not manipulate.

Also in the assistive-device category is an anklebot (a robotic device that provides stability for patients whose gait has been impaired by stroke or diseases like Parkinson’s), rehabilitation treadmills that use a functioning limb to mirror muscle control in the impaired limb to restore normal mobility, and a variety of sensor-monitoring technologies that use treadmills or other therapeutic devices.

Human partners and autonomous robotic systems

Robot learning, whether to enable a robot to serve as a “third arm” to a human technician, execute safety protocols in autonomous vehicles or recognize and adapt to changing terrain in a search-and-rescue mission, is a growing component of robotics research.

As robotics becomes more sophisticated, so do the algorithms that enable them to learn and interact with humans.

In the arena of computer vision, or the ability of a system to recognize and react to visual cues, computer science Assistant Professor Yezhou Yang cites the description of a panda in mainland China as a cat-like bear, where in Taiwan it’s identified as a bear-like cat.  In addition, a young panda more closely resembles a cat, while a mature panda looks more like a bear. It’s more important to identify the concept about the visual image than to simply assign it to a semantic category.

Artificial intelligence: Bridge between humans, autonomous systems

Rather than seeing artificial intelligence as the nemesis of humankind, Heni Ben Amor, an ASU assistant professor in Computer Information and Decisions Systems, describes AI as the mechanism that helps robots support human partners.

“AI is a set of mathematical tools that allows systems to adapt to the world we’ve created for human beings,” Ben Amor said. “It helps us live a comfortable, meaningful life, providing the systems to accommodate unmet needs in rehabilitative medicine, in our homes and in our places of work.”
