MassRobotics hosted ‘Form & Function Robotics Challenge’ received positive feedback for presenting transforming 3D printing robot technology.
Seoul National University College of Engineering (Dean Hong Yoo-seok) announced that Professor Kyu-Jin Cho's team from the Department of Mechanical Engineering won first place in the ‘2024 Form & Function Robotics Challenge’ held at the Boston Convention Center in the United States.
The challenge, hosted by MassRobotics, was held over two days from May 1st to 2nd. Professor Cho's team presented a transforming 3D printing robot technology for construction automation in space, surpassing prestigious Boston universities such as MIT, Harvard, and Tufts, as well as Cornell and Stanford, to secure first place.
Professor Cho's team developed a structure that can be stored using a Fold-and-Roll double compression method, where a structure folded in a zigzag pattern like a folding fan is wound like a tape measure. This structure can be stored in a small volume with a high compression ratio through the double compression method during storage. When unfolded, it utilizes the principle of origami to unfold into a zigzag-shaped pleated structure, transforming into a rigid form.
This structure can be deployed and stored using only one motor.
Professor Cho's team constructed a transforming frame using structures that can be stored using the Fold-and-Roll method. They integrated this frame with a conventional 3D printing device to create a transforming 3D printing device. The manufactured transforming 3D printing device can unfold from a triangular prism shape with a base of 0.8m and a height of 0.75m during storage to a maximum triangular pyramid shape with a base of 3.4m and a height of 3.6m.
This device is equipped with a 1.2mm nozzle and uses PLA, a common 3D printing material, to output structures larger than humans. In the competition, they demonstrated printing a 1.2m structure composed of 2000 layers on the concrete floor of the competition venue.
If this 3D printing device is combined with a mobile robot, the robot can autonomously move to a designated location, deploy a large frame, print the target structure, fold the frame, and move to the next task, showcasing its potential as an automated construction robot. This technology can be effectively utilized for future construction tasks on lunar bases where human access is challenging.
Furthermore, this technology can enhance the portability of large structures that require sufficient rigidity and strength, and it is expected to be applicable in various fields beyond space environments, including construction sites and disaster sites where large structures are needed.
Meanwhile, the Human-Centered Soft Robotics Research Center (Director: Professor Kyu-Jin Cho), which jointly conducted this research, has been developing various wearable soft robots for enhancing human motor skills since 2016 through interdisciplinary research encompassing mechanical engineering, computer science, medicine, clothing, and sports science.
