Abstract

We describe a controller with a fully integrated musculoskeletal model actuated by more than a hundred muscles. Inspired by a QP-based control algorithm, we improved the algorithm to control the volumetric muscles directly. Furthermore, the highly-detailed musculoskeleton was modeled using a non-manifold method and a computation time was effectively reduced through implicit jacobian computation. Our entire system can simulate the musculoskeleton model with detailed volumetric muscles in a feasible computation time.

Locomotion control for many-muscle humanoids

We present a biped locomotion controller for humanoid models actuated by more than a hundred Hill-type muscles. The key component of the controller is our novel algorithm that can cope with step-based biped locomotion balancing and the coordination of ...
Joint moments and muscle forces in walking with different heel heights
BioMed'06: Proceedings of the 24th IASTED international conference on Biomedical engineering

In this study, we determined joint moments and muscle forces in the lower extremity during walking with different heel-height shoes using the 3D motion analysis and the corresponding musculoskeletal modeling. Totally fifteen healthy women participated ...
Alteration of muscle synergy structure while walking under increased postural constraints

It is hypothesised that specific groups of muscles aka muscle synergies (MSs) are combined by the central nervous system to control a wide repertoire of movements and also simplify motor control. Therefore, studying MSs during human locomotion is of ...
