There is a need for effective design solutions to exploit the properties of origami structure with simplified assembly and improved robotic mobility. In this study, inspired by human long-standing jumps, we present a soft electrostatically driven legged accordion fold actuator made by turning a flat paper into hollow polyhedron structure with a spring like rear and capable of electrostatic pad-assisted steering and carrying loads. Without the need for integration of external actuators, the actuator is composed of the electrostatic origami actuator itself supported by a single-fold leg with fast response, easy fabrication process, and low cost. Initiated by periodic deformation around the folding hinges caused by alternating current voltage and ground reaction forces, the actuators exhibit a unique jump-slide movement outperforming other existing soft electrostatic actuators/robots in terms of relative speed. We examined the effect of different geometric and external factors on the relative speed and highlighted the significance of body scale and short-edge panels as the elastic elements, as well as operating at resonance frequency in producing effective performances. Theoretical locomotion models and finite element analysis were carried out to interpret the working principle and validate experimental results.}, journal={SOFT ROBOTICS}, author={Yang, Yiduo and Li, Mengjiao and Chen, Erdong and Mu, Weilei and Yin, Rong}, year={2024}, month={Jan} } @article{yang_liu_yin_2023, title={Fiber-Shaped Fluidic Pumps for Wearable Applications}, volume={7}, ISSN={["2524-793X"]}, url={https://doi.org/10.1007/s42765-023-00319-y}, DOI={10.1007/s42765-023-00319-y}, journal={ADVANCED FIBER MATERIALS}, author={Yang, Yiduo and Liu, Yang and Yin, Rong}, year={2023}, month={Jul} } @article{mu_li_chen_yang_yin_tao_liu_yin_2023, title={Spiral-Shape Fast-Moving Soft Robots}, volume={5}, ISSN={["1616-3028"]}, url={https://doi.org/10.1002/adfm.202300516}, DOI={10.1002/adfm.202300516}, abstractNote={AbstractSoft robots typically exhibit limited agility due to inherent properties of soft materials. The structural design of soft robots is one of the key elements to improve their mobility. Inspired by the Archimedean spiral geometry in nature, here, a fast‐moving spiral‐shaped soft robot made of a piezoelectric composite with an amorphous piezoelectric vinylidene fluoride film and a layer of copper tape is presented. The soft robot demonstrates a forward locomotion speed of 76 body length per second under the first‐order resonance frequency and a backward locomotion speed of 11.26 body length per second at the third‐order resonance frequency. Moreover, the multitasking capabilities of the soft robot in slope climbing, step jumping, load carrying, and steering are demonstrated. The soft robot can escape from a relatively confined space without external control and human intervention. An untethered robot with a battery and a flexible circuit (a payload of 1.665 g and a total weight of 1.815 g) can move at an absolute speed of 20 mm s−1 (1 body length per second). This study opens a new generic design paradigm for next‐generation fast‐moving soft robots that are applicable for multifunctionality at small scales.}, journal={ADVANCED FUNCTIONAL MATERIALS}, author={Mu, Weilei and Li, Mengjiao and Chen, Erdong and Yang, Yiduo and Yin, Jie and Tao, Xiaoming and Liu, Guijie and Yin, Rong}, year={2023}, month={May} }
