Supple robot time?
After millions of years of development, the human body is unquestionably the most advanced biomechanical mode to date, but it still holds many secrets. Now a ground-breaking structural approach proposed by Nicolas de Lussy sheds new light on the subject.
This approach, based on a lattice of hexagonal tube of variable resistance, calls into question the sliding filament theory described by Hanson and Huxley in 1955.
Contrary to the conventional view of two-dimensional muscle function, it is clear that when a muscle is contracted, it expands; the phenomenon is therefore three-dimensional.
This observation underlies Nicolas de Lussy’s theory, established following extensive study and research: the organised expansion of three motor unit types is converted into tractive force. But how? – By the spreading of the structural collagen fibres connecting the relevant structure.
The results of numerous simulations conducted by Nicolas de Lussy, based on networks of assemblies with different mechanical properties have been corroborated by state-of-the-art knowledge in the field of biomechanics. The mathematics of the simulation models have also been validated by an eminent engineering school and approved by leaders of several major companies in the robotics and construction sectors. All these endorsements confirm the potential of the initial hypothesis.
This new approach opens up a whole new field of research and development that is unprecedented in the field of supple humanoid robots. It provides the opportunity to create extremely light, yet resistant structures that can generate very high effective power outputs from a very low energy source.
