Locomotion on flowing granular ground is unlike locomotion on hard ground because feet and/or wheels experience both solid- and fluid-like forces during surface penetration. This is the essence of why navigating over granular material is a challenging undertaking for most all manmade vehicles. Places such as sandy beaches or snow covered mountain tops typically present very hard, if not unmanageable, obstacles to vehicles of all types. Yet, these same challenging environments are places teeming with animals that have developed effective navigation techniques. Studying such biological models and conducting systematic experiments with robotic models on controlled granular media our group aims to 1) build a concrete understanding of the dynamics of granular material; and 2) design a legged robotic system that can demonstrate high locomotion performance on granular media.

GRASP Lab Profile: Feifei Qian -- How a robotics researcher transforms obstacles into opportunities

Feb 11, 2020


GRASP lab fosters the development of inspiring leaders in cutting-edge robotics research. Feifei Qian was a postdoctoral researcher with Kod*lab, a research group within the GRASP Lab at Penn Engineering from 2015 to 2019. During this time, Feifei developed a framework that allows robots to view obstacles or disturbances as opportunities, and use their legs as “disturbance selectors” to choose which disturbance to keep and which to skip. She worked with geomorphologists and aeolian scientists to better understand desertification and used robots to sense and learn about the environment. In Summer 2017, Feifei participated as a mentor in the GRASP Lab’s Research Experience for Middle School Teachers. She gained a sense of responsibility to inform people’s perception of robotics and the future of robotics. Feifei strongly believes anyone can do research if they have curiosity and perseverance. In Spring 2020, Feifei started as Assistant Professor at the University of Southern California.
