SPRINT: Efficient Spectral Priors for Humanoid Athletic Sprints

arXiv:2605.28549v1 Announce Type: cross Abstract: The pursuit of humanoid athletic sprints is hindered by a scarcity of humanoid-viable kinematic reference data and the inability of existing frameworks to maintain stability during sprints. To overcome these limitations, we introduce SPRINT, a novel framework driven by efficient, frequency-adaptive spectral priors. By characterizing the fundamental periodicity of human locomotion in the frequency domain using a reference library of five discrete motion sequences, these priors generate kinematically feasible joint trajectories across a broad vel

Why this matters
Why now

The continuous advancements in AI and robotics are enabling more sophisticated control frameworks for complex tasks like bipedal locomotion, bringing humanoid robots closer to real-world deployment.

Why it’s important

This research directly addresses a critical barrier in humanoid robotics—maintaining stability and achieving athletic performance—which is essential for their widespread commercial and industrial application.

What changes

The ability to generate kinematically feasible and stable trajectories for high-speed locomotion significantly expands the potential utility and functional range of humanoid robots beyond current limitations.
