Dynamic jumping on high platforms and over gaps differentiates legged robots from wheeled counterparts.
Compared to walking on rough terrains, dynamic locomotion on abrupt surfaces requires fusing
proprioceptive and exteroceptive perception for explosive movements.
In this paper, we propose SF-TIM (Simple Framework combining Terrain Imagination and Measurement), a
single-policy method that enhances quadrupedal robot jumping agility, while preserving their fundamental
blind walking capabilities.
In addition, we introduce a terrain-guided reward design specifically to assist quadrupedal robots in high
jumping, improving their performance in this task. To narrow the simulation-to-reality gap in quadrupedal
robot learning, we introduce a stable and high-speed elevation map generation framework, enabling
zero-shot simulation-to-reality transfer of locomotion ability. Our algorithm has been deployed and
validated on both the small-/large-size quadrupedal robots, demonstrating its effectiveness in real-world
applications: the robot has successfully traversed various high platform and gaps, showing the robustness
of our proposed approach. The demo video is available here https://flysoaryun.github.io/SF-TIM.
