Abstract

A motion-based control interface promises flexible robot operations in dangerous environments by combining user intuitions with the robot's motor capabilities.However, designing a motion interface for non-humanoid robots, such as quadrupeds or hexapods, is not straightforward because different dynamics and control strategies govern their movements.We propose a novel motion control system that allows a human user to operate various motor tasks seamlessly on a quadrupedal robot.We first retarget the captured human motion into the corresponding robot motion with proper semantics using supervised learning and post-processing techniques.Then we apply the motion imitation learning with curriculum learning to develop a control policy that can track the given retargeted reference.We further improve the performance of both motion retargeting and motion imitation by training a set of experts.As we demonstrate, a user can execute various motor tasks using our system, including standing, sitting, tilting, manipulating, walking, and turning, on simulated and real quadrupeds.We also conduct a set of studies to analyze the performance gain induced by each component.(Video 1 )

  • Recent studies on motion retargeting across diverse morphologies often depend on models specific to an embodiment or task.

    “While these studies have successfully demonstrated motion retargeting from humanoid to non-humanoid morphologies, they often rely on either embodiment-specific or task-specific models.”

    From LEGATO: Cross-Embodiment Imitation Using a Grasping Tool (2025) · cites this paper as [32]

    In IV. Motion Retargeting, the paper says traditional retargeting techniques often require task-specific formulations; its Motion Retargeting Network section also describes learning a network for a single task. The Comparison to Other Methods section discusses successful human-to-non-humanoid mappings. These passages support the task-specific part of the claim, but do not establish that the studies often rely on embodiment-specific models. Page numbers are unavailable in our copy. (LLM, conf=0.82)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
