KiVi: Kinesthetic-Visuospatial Integration for Dynamic and Safe Egocentric Legged Locomotion
Peizhuo Li, Hongyi Li, Yuxuan Ma +8
Vision-based locomotion has shown great promise in enabling legged robots to perceive and adapt to complex environments. However, visual information is inherently fragile, being vu…
HeLoM: Hierarchical Learning for Whole-Body Loco-Manipulation by a Hexapod Robot
Xinrong Yang, Peizhuo Li, Hongyi Li +8
In nature, animals often need to move/manipulate objects comparable in weight/size to their own bodies. Compared to grasping and carrying, pushing provides a more straightforward a…
From Impact to Insight: Dynamics-Aware Proprioceptive Terrain Sensing on Granular Media
Yifeng Zhang, Yue Wu, Jake Futterman +5
Robots that traverse natural terrain must interpret contact forces generated under highly dynamic conditions. However, most terrain characterization approaches rely on quasi-static…
Legged Autonomous Surface Science In Analogue Environments (LASSIE): Making Every Robotic Step Count in Planetary Exploration
Cristina G. Wilson, Marion Nachon, Shipeng Liu +20
The ability to efficiently and effectively explore planetary surfaces is currently limited by the capability of wheeled rovers to traverse challenging terrains, and by pre-programm…
Inverse Resistive Force Theory (I-RFT): Learning granular properties through robot-terrain physical interactions
Shipeng Liu, Feng Xue, Yifeng Zhang +2
For robots to navigate safely and efficiently on soft, granular terrains, it is crucial to gather information about the terrain's mechanical properties, which directly affect locom…
Scout-Rover cooperation: online terrain strength mapping and traversal risk estimation for planetary-analog explorations
Shipeng Liu, J. Diego Caporale, Yifeng Zhang +17
Robot-aided exploration of planetary surfaces is essential for understanding geologic processes, yet many scientifically valuable regions, such as Martian dunes and lunar craters,…
