A recent study conducted by researchers at Northwestern University and published in the journal Advanced Intelligent Systems has presented a flexible actuator that promises to contribute significantly to the field of soft robotics and could be used in the future in a variety of industries and even for medical care.
About the new soft robotic actuator
The research team, led by Taekyoung Kim, Pranav Kaarthik, and Ryan L. Truby, has developed a new type of architectural soft actuator designed to perform motorized extension movements. This actuator, composed of a polyurethane polyurethane material thermoplastic material and a rubber bellows shaft, exhibits a unique ability to extend linearly while maintaining full flexibility.
Meticulous tests have been carried out to mechanically characterize this actuator. The results have been promising, demonstrating its ability to withstand and adapt to diverse conditions without losing efficacy. Demonstrated applications include a crawling robot that can maneuver through tight and complex spaces, ideal for industrial inspections or rescues in harsh environments.

Tests, results and future applications
Detailed tests carried out by the researchers have demonstrated the actuator’s remarkable ability to generate a maximum thrust force of approximately 8 N and a maximum elongation of 45% of its initial length, which is significant for use in practical applications. This superior performance underscores its potential not only for maneuvering through tight spaces, but also for performing tasks that require considerable force without losing precision or flexibility.
These results promise to revolutionize the operational capabilities of robots in both industrial and medical environments, providing more efficient and adaptable solutions than current systems.
Finally, the researchers envision a wide range of applications for their innovation, from improving industrial equipment to improvement of industrial equipment to the creation of more efficient and adaptable prostheses for patients requiring motor assistance. This study, in addition to opening new doors in the field of soft robotics, sets a precedent for the development of more responsive and adaptive technologies.
