Nonlinear behavior

Definition

Nonlinear behavior refers to the response of a system where changes in input do not produce proportional changes in output. This means that small adjustments in control variables can lead to unexpectedly large or complex movements and actions. In the context of soft continuum manipulators, this characteristic allows for greater flexibility and adaptability, which is crucial for interacting with various environments and tasks.
