Undulatory Swimming in Sand: Subsurface Locomotion of the Sandfish Lizard
Ryan D. Maladen, Yang Ding, Chen Li +1
The desert-dwelling sandfish (Scincus scincus) moves within dry sand, a material that displays solid and fluidlike behavior. High-speed x-ray imaging shows that below the surface,…
The need for and feasibility of alternative ground robots to traverse sandy and rocky extraterrestrial terrain
Chen Li, Kevin Lewis
Robotic spacecraft have helped expand our reach for many planetary exploration missions. Most ground mobile planetary exploration robots use wheeled or modified wheeled platforms.…
Robust Keyframe-based Dense SLAM with an RGB-D Camera
Haomin Liu, Chen Li, Guojun Chen +3
In this paper, we present RKD-SLAM, a robust keyframe-based dense SLAM approach for an RGB-D camera that can robustly handle fast motion and dense loop closure, and run without tim…
Sensitive dependence of the motion of a legged robot on granular media
Chen Li, Paul B. Umbanhowar, Haldun Komsuoglu +2
Legged locomotion on flowing ground ({\em e.g.} granular media) is unlike locomotion on hard ground because feet experience both solid- and fluid-like forces during surface penetra…
