> ABSTRACT:
> This talk presents two recent efforts where machine learning addresses
> fundamental challenges in wearable robot modeling and control. The first
> contribution addresses the robot side: a hybrid Neural ODE framework for
> modeling artificial muscle dynamics that embeds physical structure into a
> learned model, enabling reliable stiffness control over a 126–176 N/mm
> range. The second addresses the human side: a transformer-based neural
> decoder that estimates joint impedance directly from EMG, learning
> time-varying stiffness and equilibrium position under a least-action prior
> — the assumption that voluntary movement is energetically efficient. These
> two contributions reflect a common principle: that both sides of the
> human-robot interface — the robot's dynamics and the user's intent — must
> be learned rather than prescribed. The talk closes with an emerging
> direction: Hebbian self-organization of spinal-like reflex networks, which
> may ultimately replace both learned models with a single continuously
> adapting system, removing the need for supervised training altogether.
