Actuation mechanisms

Definition

Actuation mechanisms are systems or components that convert energy into motion to perform a specific action or task, often mimicking biological movements. These mechanisms play a crucial role in neuromorphic engineering, as they enable the physical responses of artificial systems based on sensory inputs, closely resembling natural processes. They are vital for creating responsive and adaptive devices that can interact with their environment in real-time.
