Force Transmission

Definition

Force transmission refers to the process by which forces are transferred and distributed through a structure or system, allowing for movement or deformation. This concept is crucial in understanding how soft robots interact with their environments and how soft orthoses support human movement, ensuring that the forces generated by actuators or external loads are effectively transmitted to achieve desired outcomes.
