Real-World Helper Exoskeletons Just Got Closer to Reality

Matthew Gombolay and Aaron Young pose in the lab while Ph.D. researchers work on a leg exoskeleton device.

Researchers Matthew Gombolay, left, and Aaron Young used the lower-limb exoskeleton demonstrated in the background to test their new approach to creating exoskeleton controllers. They use huge amounts of existing data on how people move to create functional controllers able to provide meaningful assistance. And unlike earlier controllers, they do not require hours and hours of additional training and data collection with each specific exoskeleton device.

To make useful wearable robotic devices that can help stroke patients or people with amputated limbs, the computer brains driving the systems must be trained. That takes time and money — lots of time and money. And researchers need specially equipped labs to collect mountains of human data for training.

Even when engineers have a working device and brain, called a controller, changes and improvements to the exoskeleton system typically mean data collection and training start all over again. The process is expensive and makes bringing fully functional exoskeletons or robotic limbs into the real world largely impractical.

Not anymore, thanks to Georgia Tech engineers and computer scientists.

They’ve created an artificial intelligence tool that can turn huge amounts of existing data on how people move into functional exoskeleton controllers. No data collection, retraining, and hours upon hours of additional lab time required for each specific device.

Their approach has produced an exoskeleton brain capable of offering meaningful assistance across a huge range of hip and knee movements that works as well as the best controllers currently available. Their worked was published Nov. 19 in Science Robotics.

Professor Earns Test-of-Time Award at AI and Computer Gaming Conference

Mark Riedl

One of the top conferences for AI and computer games is recognizing a School of Interactive Computing professor with its first-ever test-of-time award.

At its event this week in Alberta, Canada, the AAAI Conference on Artificial Intelligence and Interactive Digital Entertainment (AIIDE) is honoring Professor Mark Riedl. The award also honors University of Utah Professor and Division of Games Chair Michael Young, Riedl’s Ph.D. advisor.

Riedl studied under Young at North Carolina State University.

Their 2005 paper, From Linear Story Generation to Branching Story Graphs, highlighted the challenges of using AI to create interactive gaming narratives in which user actions influence the story’s progression. 

In 2005, computer game systems that supported linear, non-branching games were widely used. Riedl introduced an innovative mathematical formula for interactive stories ranging from choose-your-own-adventure novels to modern computer games.

“We didn’t use the term ‘generative AI’ back then, but I was working on AI for the generation of creative artifacts,” Riedl said. “This was before we had practical deep learning or large language models.

“One of the reasons this paper is still relevant 20 years later is that it didn’t just present a technology, it attempted to provide a framework for solving a grand challenge in AI.”

That challenge is still ongoing, Riedl said. Game designers continue to struggle with balancing story coherence against the amount of narrative control afforded to users.

“When users exercise a high degree of control within the environment, it is likely that their actions will change the state of the world in ways that may interfere with the causal dependencies between actions as intended within a storyline,” Riedl and Young wrote in the paper.

“Narrative mediation makes linear narratives interactive. The question is: Is the expressive power of narrative mediation at least as powerful as the story graph representation?”

AIIDE is being held this week at the University of Alberta in Edmonton, Alberta. Riedl will receive the award on Wednesday.
