This paper presents studies of the coordination of voluntary human arm movements. A
mathematical model is formulated which is shown to predict both the qualitative features and the …

According to the equilibrium trajectory hypothesis, multi-joint arm movements are achieved
by gradually shifting the hand equilibrium positions defined by the neuromuscular activity. …

In recent years different lines of evidence have led to the idea that motor actions and movements
in both vertebrates and invertebrates are composed of elementary building blocks. The …

Even simple movements require the coordination of a bewildering number of muscles. How
does the brain cope with this task? How can we begin to understand this extraordinarily …

Movement of multiple segment limbs requires generation of appropriate joint torques which
include terms arising from dynamic interactions among the moving segments as well as from …

Two approaches to the study of movement planning were contrasted. Data on the drawing
of complex two-dimensional trajectories were used to test whether the covariations of the …

When do learning-related changes in performance occur? Here we show that the knowledge
of a sequence of movements evolves through several distinctive phases that depend on …

In this paper we study the question of how an aimed arm movement is modified in response
to a sudden change in target location occurring during the reaction or movement time. …

In this paper, we describe our recent results in the development of a new class of soft,
continuous backbone ("continuum") robot manipulators. Our work is strongly motivated by the …
