Scientists have developed a type of robotic exoskeleton integrated with artificial intelligence (AI) that enables users to perform a variety of tasks with less effort and energy.
Researchers at North Carolina State University in the United States have created a robotic exoskeleton that helps users save energy while walking, running, and climbing stairs. This robotic exoskeleton is equipped with AI to recognize the user’s movement patterns, thereby optimizing its movements to better assist the wearer.

Dr. Hao Su, an associate professor of Mechanical and Aerospace Engineering at North Carolina State University and the research team leader, stated that the robotic exoskeleton is still in the development phase and requires training to operate more efficiently. However, the integration of AI algorithms has accelerated the training process.
To shorten the training time for the robotic exoskeleton, the research team used videos of walkers in various postures and styles as a training database for the AI system on the device.
“We don’t need to train the robotic exoskeleton using actual humans; we can use simulated environments to train the AI system on the device,” Dr. Hao Su explained.
The advantage of this robotic exoskeleton is its compact size, with a processor mounted at the back of a belt and motors attached to the wearer’s legs to assist their movements.
During testing, the robotic exoskeleton enabled users to save significantly more energy while performing activities, meaning they would have more energy and increased endurance for longer activities.
For instance, during walking, users of the robotic exoskeleton consumed 24.3% less energy, saved 13.1% energy while running, and saved 15.4% energy while climbing stairs compared to when they were active without the support of the robotic exoskeleton.

Dr. Hao Su noted that the AI-integrated robotic exoskeleton is still in its early stages of development but holds great potential. Beyond assisting people in saving energy and exerting less effort during activities, this robotic exoskeleton could also be used for individuals with mobility limitations or disabilities, helping them move more easily.
The research team also plans to integrate the robotic exoskeleton into prosthetic limbs, allowing amputees to walk with the aid of the robotic exoskeleton instead of relying on wheelchairs.
Additionally, this robotic exoskeleton could be applied in military and industrial settings, enhancing the strength of the wearer to enable them to cover longer distances, move faster, or carry heavier objects.
“Currently, the robotic exoskeleton is still under development, but it has significant potential for real-world applications. In about a year, I believe this robotic exoskeleton will become more flexible and intelligent, supporting all activities for both healthy individuals and those facing mobility challenges,” Dr. Hao Su shared.
