Balancing on a tightrope or a slackline is an example of a neuromechanical task where the
whole body both drives and responds to the dynamics of the external environment, often on …

Response lags are generic to almost any physical system and often play a crucial role in the
feedback loops present in artificial nanodevices and biological molecular machines. In this …

The causes of falling in the elderly are multi-factorial. Three factors that influence balance
stability are the time delay, a sensory dead zone and the maximum ankle torque that can be …

Embodiment is a crucial concept for the autonomy and adaptivity of systems working in the
physical world with high degrees of uncertainty and complexity. The physical bodies of …

The output of an accelerometer often has coupled components of displacement and
acceleration, and is rarely used individually for balancing tasks. In order to balance a …

This paper introduces control concepts that are important for ensuring stability. To clarify
these concepts, a series of experiments using a simple task of stick balancing will be …

A nonlinear model for human balancing subjected to a saturated delayed proportional–
derivative–acceleration (PDA) feedback is analysed. Compared to the proportional …

During quiet standing, humans tend to sway with a distinctive pattern that has been difficult
to capture with simple engineering models. We have developed a nonlinear optimal control …

During standing balance, kinematics of postural behaviors have been previously observed
to change across visual conditions, perturbation amplitudes, or perturbation frequencies …

Models for the stabilization of an inverted pendulum figure prominently in studies of human
balance control. Surprisingly, fluctuations in measures related to the vertical displacement …
