Researchers testing next-generation ankle braces for stroke survivors

Researchers testing next-generation ankle braces for stroke survivors Alexander Jame鈥� Tue, 07/15/2025 - 12:30

Nearly 80% of all stroke survivors experience walking issues, according to a study in the American Heart Association journal.

For some of them, the solution is simple: ankle-foot orthoses (AFOs), otherwise known as ankle braces. These wearable, assistive devices are designed to enhance mobility and make walking easier post-stroke.

But the functionality of these braces is still very limited. In fact, a report in the National Library of Medicine said that only a third of stroke patients see walking improvements when paired with an AFO.

That鈥檚 why Cara Welker, an assistant professor in the Paul M. Rady Department of Mechanical Engineering, is leading a new, collaborative research project that aims to redefine this relationship. Her team is developing a next-generation AFO that doesn鈥檛 just support movement鈥攊t enhances it.

A quick look at the next-generation AFO prototype, designed by Associate Professor Elisa Arch at the University of Delaware.

鈥淪troke survivors or others using these assistive devices walk slower, and it takes more effort for them to move,鈥� said Welker, who is also affiliated with the Biomedical Engineering Program, the Robotics Program and the BioFrontiers Institute. 鈥淢ovement is important, not just for getting around, but for our quality of life and physical health. If we can help someone walk faster or get closer to how a healthy person walks, then we see that as a success.鈥�

Funded by the National Science Foundation (NSF), the three-year, $600,000 project is a collaboration with Associate Professor Elisa Arch at the University of Delaware. It begins with a unique AFO prototype that the two believe has the potential to transform the way assistive devices are designed.

Current ankle brace technology offers only a single stiffness profile that operates like a simple spring. They can be effective for some, but Welker says the human ankle is much more complex than that.

鈥淭he single stiffness profile doesn鈥檛 mimic normal ankle function when walking,鈥� Welker said. 鈥淚t can鈥檛 adapt to the stiffness or the biological angle of a human ankle, which means many brace users still have trouble walking.鈥�

To address this, Arch developed a new AFO that can transition between two different stiffness profiles instead of one. Think of it as a more personalized brace that is tailored to the complexity of the ankle鈥攁s a person walks and their ankle angle changes, the brace can change how it behaves to provide better support.

But the challenge of the research project isn鈥檛 necessarily in the design. Welker says brace customization is currently largely based on trial and error. The lack of precise modeling makes it difficult to pair different stiffness profiles and properties with the needs of the user.

鈥淭he device we have is very promising, but we don鈥檛 know how to prescribe these different stiffnesses based on someone鈥檚 specific set of weaknesses,鈥� said Welker. 鈥淚t might likely be different from one person to another since stroke manifests itself in many ways.鈥�

A series of tests, using the powered exoskeleton, motion capture cameras and integrated treadmills, being performed inside of the Welker Lab space.

Using her cutting-edge Welker Lab space鈥攅quipped with a powered exoskeleton, motion capture cameras, ground-integrated treadmills and force plates鈥擶elker鈥檚 role is to test the device. The goal is to see the AFO in action, model how changing these device parameters affect walking, and optimize along the way wherever possible.

鈥淭here鈥檚 this technique called human-in-the-loop optimization. It involves changing behavior of an assistive device and measuring how these changes affect certain user metrics that are deemed important,鈥� Welker said. 鈥淲e want to use this technique to measure things like walking speed or energy expenditure. By doing this, we can select the parameters that best optimize for outcome metrics we care about for a specific person.鈥�

Welker has aspirations beyond the NSF-funded project, as well. She believes their research can be manufactured at scale and prescribed in clinics, helping stroke survivors and brace users around the world achieve normal ankle function.

She also believes the work done during this project can positively impact her other projects. Whether it鈥檚 in the realm of AFOs or other assistive devices like prosthetics, Welker鈥檚 research is well-rounded and diverse. But she says her unique lab space with different assistive devices and the ability to quantify how people interact with them ties it all together.

鈥淲e work on many different projects, but it鈥檚 great because we can integrate them under the same human motion analysis system,鈥� said Welker. 鈥淚鈥檓 excited to work on these types of studies, not just for people post-stroke, but also amputees. I believe the work we do will help improve the quality of life for many people.鈥�

Nearly 80% of all stroke survivors experience walking issues and turn to ankle braces for increased support, but ankle braces are still very limited and many stroke survivors report no improvements when using them. Assistant Professor Cara Welker is leading a new, collaborative research project that aims to transform the way these assistive devices are designed.

Robots and chemistry isn鈥檛 just a fun combo. Bruns says it鈥檚 the future

Robots and chemistry isn鈥檛 just a fun combo. Bruns says it鈥檚 the future Alexander Jame鈥� Fri, 06/06/2025 - 16:02

Carson Bruns is working to lend chemists a hand鈥攍iterally鈥攂y bringing collaborative robots into chemical wet labs.

Bruns, an assistant professor in the Paul M. Rady Department of Mechanical Engineering at 色戒成人直播, is leading the charge on a project that he and his team like to call 鈥渞obochemistry.鈥� Their goal is to create robotic sidekicks that can assist chemists with burdensome or unsafe tasks that they may encounter in a wet lab on a daily basis.

According to the U.S. Bureau of Labor Statistics, chemists and materials scientists held nearly 100,000 jobs in 2023 and overall employment is expected to grow eight percent over the next 10 years.

But unlike other large and growing industries, Bruns says chemical research and development has remained devoid of robots, often leading to injuries and considerable risks in the workplace.

鈥淭here are a lot of potential benefits for introducing robots into a chemical lab that haven鈥檛 been explored yet,鈥� said Bruns, who is also affiliated with the ATLAS Institute, Biomedical Engineering Program and Materials Science and Engineering Program. 鈥淥ur angle involves trying to reduce work burdens and safety risks, develop robots that collaborate with humans instead of replacing them, and increase accessibility so that even people with disabilities can perform chemistry.鈥�

Middle school students exploring the intersections of robotics and chemistry during one of the "robochemistry" interactive workshops led by Bruns and his team.

The project, funded by the National Science Foundation, is in collaboration with researchers from the University of North Carolina at Chapel Hill and 色戒成人直播鈥檚 Department of Computer Science. It started with an extensive observation-based task analysis that allowed Bruns and his team in the Emergent Nanomaterials Lab to develop a strong understanding of the various tasks that chemists were performing regularly in a wet lab.

After observing, interviewing and surveying their chemist test subjects, Bruns and his group were able to identify an array of different tasks that can potentially benefit from human and robot collaboration.

鈥淲e learned right away that chemists don鈥檛 really like doing a purification task called dialysis that is very common in a wet lab. It鈥檚 repetitive, it takes a lot of time and sometimes chemists have to come back to the lab in the middle of the night to change dialysis bags, which they don鈥檛 want to do.鈥� Bruns said. 鈥淚t seemed like a great case for a robot, so we built a robotic system automating the dialysis process.鈥�

Bruns says his team of researchers has a list of other potential benefit areas, as well, including simple tasks like stabilizing a flask or offering a third hand to hold something for chemists when they need it. They are even trying to find solutions for more complex safety issues so that chemists can stay far away from violent and dangerous reactions.

But that鈥檚 not where the project ends. There is also an outreach portion aimed at improving science education and enhancing youth interest in science.

Led by PhD student Diane Jung, Bruns and his team ran a four-day interactive workshop series at a local middle school in 色戒成人直播. These workshops invited middle school students to build robots with Legos and use them to perform various chemistry experiments鈥攕omething that鈥檚 already happening in Bruns鈥� lab.

鈥淲e鈥檝e been building ordinary automation tools out of Lego because it鈥檚 cheaper and reconfigurable. When you don鈥檛 need it anymore, you just disassemble it and build it into something else,鈥� said Bruns. 鈥淪o we thought we could use this Lego thing we had going on in our lab already to appeal to a younger audience and show kids the fun and evolving intersection between chemistry and robotics in real time.鈥�

During the workshop series, Bruns noticed various groups of students approaching experiments with unique perspectives and ideas. He said it was inspiring to see young kids actively engage with the science in front of them.

But most importantly, he saw the kids have fun.

鈥淭hinking back to young Carson when he was a kid鈥攊t always just seemed very fun to me,鈥� Bruns said. 鈥淚 had positive role models in my life who also believed science was fun, so that was our goal with this part of the project. To help kids have a more positive association with the idea of science and engineering.鈥�

Assistant Professor Carson Bruns is leading the charge on an NSF-funded project that he and his team like to call "robochemistry." Their goal is to create robotic sidekicks that can assist chemists with burdensome or unsafe tasks that they may routinely encounter in a wet lab. But that's not all: this unique blend of bots and beakers can also inspire youth interest in science.

Tiny robot team could be a gamechanger for safety inspections

Tiny robot team could be a gamechanger for safety inspections Alexander Jame鈥� Wed, 05/21/2025 - 09:29

One slithers. One crawls. Neither looks like much on their own. But together, they form a super team鈥攐ne that might just change how we inspect the most complicated machines in the world.

Kaushik Jayaram, an assistant professor in the Paul M. Rady Department of Mechanical Engineering at 色戒成人直播, is working to build the next generation of robot inspection tools by studying some of nature鈥檚 simplest creatures.

This robotic duo is about as odd as it is ingenious: tiny, insect-inspired robots paired with inflatable vine-like robots that grow like plants and curl like snakes. These high-tech helpers can navigate a complex maze of machinery and squeeze through the tightest of spaces鈥攍ike the guts of a jet engine鈥攖o potentially perform non-destructive evaluation faster, cheaper and better than ever before.

The tiny mCLARI robot, developed by Assistant Professor Kaushik Jayaram and his team in the Animal Inspired Movement and Robotics Laboratory.

鈥淚f you look at the infrastructure around us, there are a lot of buildings, bridges, dams and machines that have all of these little nooks and crannies,鈥� said Jayaram, who is also affiliated with the BioFrontiers Institute, the Biomedical Engineering Program, the Robotics Program and the Materials Science and Engineering Program. 鈥淭hey need very careful, regular inspection and maintenance, but there鈥檚 just no easy, cost-effective way to get in.鈥�

Jayaram said there is also an element of public safety involved. According to the Federal Aviation Administration, nearly 15% of aviation accidents are caused by mechanical malfunction.

In just this year alone, the National Transportation Safety Board has reported 94 aviation accidents, 13 of which have been identified as fatal incidents.

鈥淲hen it comes to tasks such as flying, where human safety is paramount, we need aircraft technology and machinery to work 100% of the time,鈥� Jayaram said. 鈥淥ur research is one of the efforts to address these concerns using the advantages of robotics.鈥�

The work, in collaboration with Laura Blumenschein at Purdue University, has drawn interest from the U.S. Air Force Research Laboratory. They鈥檝e awarded the two researchers a three-year, $1.4 million grant to prove these small robots can work together to produce big results.

But as unlikely as this robotic team might seem, Jayaram believes they have the perfect blend of 鈥渙ffense鈥� and 鈥渄efense鈥� to get these dirty and delicate jobs done.

First on the roster is Jayaram鈥檚 mCLARI microrobot. This tiny machine鈥攚eighing in at less than a gram鈥攃an climb, squeeze through cracks the size of a penny and move with a millimeter precision.

However, due to its small stature, it struggles to carry any extra weight. Large batteries and electronics are incompatible with the little robot, and without them it cannot travel long distances or maneuver tight spaces effectively.

The inflatable vine-like robot, developed by Laura Blumenschein, an assistant professor at Purdue University.

That鈥檚 where its vine-like teammate comes in. This robot can inflate like a party favor, allowing it to carry more weight and conform to the environment. In Jayaram鈥檚 vision, the inflatable snake can act as mCLARI鈥檚 personal Uber driver, negotiating constraints of tight spaces and dropping the tiny robot directly at the site of inspection.

Once in location, Jayaram said the mCLARI robot, fitted with cameras and miniature evaluation sensors, can gather and transmit real-time data for offline analysis. When it鈥檚 done, it can hop right back on the snake-like robot and the team can make the winding journey back home, saving hours of evaluation time and thousands of dollars in service costs in the process.

鈥淓ach of the robotic systems have their own pros and cons,鈥� said Jayaram. 鈥淏y combining the strengths of these two robots, we鈥檙e overcoming the disadvantages to create a single collaborative system that can give us quick insight into these compact and confined spaces.鈥�

But this tiny squad of robots is capable of much more than just inspection. In fact, Jayaram dreams of a day where his insect and vine-inspired robotic friends can be deployed in a variety of scenarios where being small, agile and adaptive are a premium.

Maybe one day this robotic team can play a vital role in environmental monitoring to detect high-risk wildfire zones and prevent ecological damage. Or maybe they can be used in disaster response situations鈥攍ike a collapsed building鈥攖o help save human lives.

Jayaram said the possibilities are truly endless.

鈥淭hese small, confined crevices and spaces are actually way more ubiquitous than we originally thought. Even in the medical arena鈥攊f we shrink these robots even further, make them shapeshift, and use biocompatible materials, maybe our technology can one day be crawling inside our bodies, detecting and releasing blood clots or taking measurements just like a pill,鈥� Jayaram said. 鈥淲e get very excited when we think about the future. If we can build systems that can effectively navigate the world and combine them with sensors, we can do a lot.鈥�

Assistant Professor Kaushik Jayaram, in collaboration with Laura Blumenschein, has received a $1.4 million grant from the U.S. Air Force Research Laboratory to develop a tiny robot super team capable of navigating a complex maze of machinery and squeeze through the tightest of spaces鈥攍ike the guts of a jet engine鈥攖o potentially perform non-destructive evaluation faster, cheaper and better than ever before.
