    A Breakthrough in Robotics: Insect-Scale Robots Show Remarkable Long-Jumping Ability

    A team of engineers from the University of Illinois has achieved a groundbreaking milestone in robotics with their study on the long-jumping motion of 3-D-printed insect-scale robots. Led by Professor Sameh Tawfick, the team’s study, published in the journal Smart Materials and Structures, showcases the first-ever demonstration of long jumping in insect-scale robots.

    Previous limitations to jump performance in insect-scale robots were primarily due to the challenges associated with small-scale manufacturing processes and the limited availability of materials and miniature actuators. However, Tawfick’s team overcame these obstacles by utilizing coiled artificial muscle actuators and projection additive manufacturing, resulting in a monolithic elastomeric robot design inspired by the jumping mechanism of a locust.

    The insect-scale prototype features a lightweight elastomer body and an artificial muscle made from coiled nylon fishing line. The research team developed machines capable of producing these miniature coils. Through additive manufacturing, they designed and tested 108 robot iterations, with the smallest robot weighing only 0.216 grams but capable of jumping an impressive 60 times its body size horizontally.

    The development of a long-jumping insect-scale robot holds significant implications for various fields, including agriculture and maintenance. Future iterations of these robots could be equipped with sensors to collect data by contacting crops or exploring machinery, offering non-destructive evaluation capabilities. Additionally, the robots’ low production cost makes them highly practical for fleet sensing applications.

    Moving forward, the team plans to focus on advancing motion planning algorithms to optimize the robots’ jump efficiency and maximize battery life. They also aim to investigate uncertainty factors introduced by the jumping motion. Ultimately, their goal is to deploy these insect-scale robots on small missions that involve multiple jumps to reach designated targets, gather images, and return to their starting point.

    The team’s pioneering work not only sets a new standard in the field of robotics but also provides a theoretical model for other researchers to build upon. The prospects of long-jumping robots hold vast potential for various industries, and the researchers are excited to see their methods and findings embraced by the wider scientific community.
