Challenges and New Approaches to Proving the Existence of Muscle Synergies of Neural Origin
This work uses cadaveric experiments and computational models to perform a crucial thought experiment and develop an alternative explanation of how muscle synergies could be observed without the nervous system having controlled muscles in groups. Expand

This stochastic analysis of anatomical variability redefines the debate on whether a single generic biomechanical model can represent the entire population, or if subject-specific models are necessary, and suggests a practical third alternative: that anatomical and functional variability can be captured by a finite set of model-types.

Design and control of tensegrity robots for locomotion
The results demonstrate that tensegrity structures can provide the basis for lightweight, strong, and fault-tolerant robots with a potential for a variety of locomotor gaits. Expand
The Tendon Network of the Fingers Performs Anatomical Computation at a Macroscopic Scale
The cadaveric experiments and computer simulations show that the tendon network of the fingers performs logic computation to preferentially change torque production capabilities, and the structural complexity of this tendon network may in fact be critical to understanding brain-body coevolution and neuromuscular control.

Evolutionary form-finding of tensegrity structures
It is shown that an evolutionary algorithm can be used to explore the space of arbitrary tensegrity structures which are difficult to design using other methods, and determine new, non-regular forms. Expand
Estimating Effective Degrees of Freedom in Motor Systems
Given the complex nature of experimental and biological data, it is necessary and feasible to complement PCA with methods that take into consideration the nonlinear properties of biological systems for a more robust estimation of their DOFs. Expand
Beta Band Corticomuscular Drive Reflects Muscle Coordination Strategies
Findings are interpreted to show that beta-band coherence is reflective of a synergistic control strategy in which the cortex binds task-related motor neurons into functional units. Expand
Muscle Synergies Heavily Influence the Neural Control of Arm Endpoint Stiffness and Energy Consumption
Results provide further evidence that the benefits and disadvantages of muscle synergies go hand-in-hand with the structure of feasible muscle activation patterns afforded by the mechanics of the limb and task constraints. Expand
Gait production in a tensegrity based robot
The design of legged robots for movement has usually been based on a series of rigid links connected by actuated or passively compliant joints. However, the potential utility of tensegrity, in whichExpand
