This research presented the design and development of 3D-printed origami actuators for a soft robot with amphibious locomotion and tongue hunting capabilities. Two different types of programmable origami actuators were designed and manufactured, namely Z-shaped and twist tower actuators. In addition, two actuator variations were developed based on the Z-shaped actuator, including the pelvic fin and the coiling\/uncoiling types. The Z-shaped actuators were used for the rear legs to facilitate the locomotion of the water-like frogs. Meanwhile, the twisted tower actuators were used for the rotation joints in the forelegs and for locomotion on land. The pelvic fin actuator was developed to imitate the land locomotion of the mudskipper, and the coiling\/uncoiling actuator was designed for tongue hunting motion. The origami actuators and soft robot prototype were tested through a series of experiments, which showed that the robot was capable of efficiently moving in water and on land and performing tongue hunting motions. Our results demonstrate the effectiveness of these actuators in producing the desired motions and provide insights into the potential of applying 3D-printed origami actuators in the development of soft robots with bioinspired features.<\/jats:p>","DOI":"10.1089\/soro.2023.0079","type":"journal-article","created":{"date-parts":[[2024,2,8]],"date-time":"2024-02-08T17:16:33Z","timestamp":1707412593000},"page":"650-669","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":27,"title":["3D-Printed Origami Actuators for a Multianimal-Inspired Soft Robot with Amphibious Locomotion and Tongue Hunting"],"prefix":"10.1177","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6216-7437","authenticated-orcid":false,"given":"Yang","family":"Yang","sequence":"first","affiliation":[{"name":"School of Automation, Nanjing University of Information Science and Technology, Nanjing, China."},{"name":"Jiangsu Province Engineering Research Center of Intelligent Meteorological Exploration Robot, Nanjing University of Information Science and Technology, Nanjing, China."},{"name":"Jiangsu Collaborative Innovation Center of Atmospheric Environment and Equipment Technology (CICAEET), Nanjing University of Information Science and Technology, Nanjing, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuan","family":"Xie","sequence":"additional","affiliation":[{"name":"School of Automation, Nanjing University of Information Science and Technology, Nanjing, China."},{"name":"Jiangsu Province Engineering Research Center of Intelligent Meteorological Exploration Robot, Nanjing University of Information Science and Technology, Nanjing, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Automation, Nanjing University of Information Science and Technology, Nanjing, China."},{"name":"Jiangsu Province Engineering Research Center of Intelligent Meteorological Exploration Robot, Nanjing University of Information Science and Technology, Nanjing, China."},{"name":"Tianchang Research Institute of NUIST, Tianchang, Anhui, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunquan","family":"Li","sequence":"additional","affiliation":[{"name":"Shien-Ming Wu School of Intelligent Engineering, South China University of Technology, Guangzhou, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feifei","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mechanical System and Vibration, Shanghai Jiao Tong University and Robotics Institute, School of Mechanical Engineering, Shanghai Jiao Tong University, Shanghai, China."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,8,21]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.oceaneng.2021.108862"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1088\/1361-665X\/ab7738"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-020-03153-z"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1089\/soro.2019.0094"},{"issue":"17","key":"e_1_3_4_6_2","first-page":"2104482","article-title":"Glowing Sucker Octopus (Stauroteuthis syrtensis)\u2014Inspired soft robotic gripper for underwater self-adaptive grasping and sensing","volume":"9","author":"Wu M","year":"2022","unstructured":"Wu M, , Zheng X, , Liu R, et al.
